Reset ML-1640 and ML-2240 for Refill Toner
As I’ve shared on my previous post about how I tried to look for soft-solution for resetting a Samsung ML-2240 so it can use refill toner, in this post I will give the download link and the howto. Instead of giving you the whole package, I provide them in 2 packages for each printer model, the raw package and the simple package.
The Raw Package contains the original firmware upgrader from Samsung with the patcher and firmware downloader. With this package you’ll need to run the complete steps I did.
The Simple package contains only the patched version of firmware so you only need to do the final step I did.
Feel free to use whichever package you prefer. But before we begin, please read carefully these facts:
- The patcher are NOT made by me, all credit goes to the original creator which I unfortunately don’t know
- The firmware upgrader included in the raw package are official version downloaded from Samsung website
- The firmware file included in the simple package are the patched version
- I provide the links and the manual but please use it at your own risk
- I’ve run the patched for a Samsung ML-2240 and it worked, but I never test the fix for ML-1640, however I also supply the file because it’s provided by the same patcher
- My operating system is Windows XP SP2
Raw Package for ML-1640

[...] of the global world « “Weird Al” Yankovic:You Don’t Love Me Anymore Reset ML-1640 and ML-2240 for Refill Toner [...]
November 30th, 2009 at 6:17 pm
that’s awesome. But will this permanently fix the problem or do you have to keep running this fix every time the toner runs low?
November 30th, 2009 at 9:55 pm
Hi smith, I can’t really give a straight answer right now, but we have actually refilled the toner twice by now and I’ve only done this reset once. I didn’t even know about the 2nd refill since the printer user doesn’t inform me about it.
The printer still print perfectly with no more annoying exhausted toner alert. Just to be sure, I’ve asked them to inform me first before doing the next refill. Sorry, but I have to wait for their next call for better answer
December 2nd, 2009 at 11:39 pm
hi i reset a ML-2240 printer with simple package, and i send to print 200 page then verify the selftest and said “Toner page Count” 6 pages maybe this help you
December 9th, 2009 at 11:06 pm
Hi Marco, many thanx for the info. That’s really smart. But I’m currently very busy in the office, I don’t have the chance to check the counter as you did. Perhaps, I will later. But just fyi, we have changed the toner for more than 3 times without doing anymore reset, so I think, yes, you only need to do it once
December 10th, 2009 at 9:39 pm
Great!
It’s worked for my Samsung ML-1640, I try simple packege & my SAMSUNG ML-1640 working well.
December 11th, 2009 at 9:47 pm
Hi Prinse, that’s great news
thank you for confirming back to us
December 15th, 2009 at 10:55 pm
kalo buat samsung ML-2570 ada ga ya ? udah googling kok ga nemu2..
December 17th, 2009 at 11:10 pm
wah, sori mas samsung
gw cuma dapet solusi buat 2 jenis printer di atas itu, ML-1640 dan ML-2240 
December 19th, 2009 at 11:17 pm
I also use the simple crack for the 1640. And it works fine. It was done for about 5 sekonds.
Dose anybody check this for a tuner without chip?
December 20th, 2009 at 10:47 pm
mas nanti reset lagi ga? atau itu sudah ga akan pernah reset lagi.
December 22nd, 2009 at 10:44 am
@callito: good to hear from you, but sorry i dont really understand what you mean with toner without chip
@idham: halo mas idham, sampai sekarang gw sendiri hanya melakukan sekali dan toner sudah diganti berkali-kali tanpa masalah
December 23rd, 2009 at 12:32 am
thx its really works
December 25th, 2009 at 6:14 am
@callito: I guess that you mean “starter” toner which dint have chip?
well i used the simple method on 1640 with starter toner which firstly had capacity of 700 pages but after patching has capacity of 1500 pages. total page count stayed the same -170 pages but the toner status is 100%! thanx kocu. very simple, very useful
December 28th, 2009 at 9:00 pm
hi bane, thanx for helping with answer for callito
I’m glad I could help a bit by providing the info and files
December 29th, 2009 at 2:34 am
After doing this on my ml1640 when i want to turn it on after downloading and pressing key and turning of the printer it won’t start anymore. When I switch to on, red light and amber light will go on for a second and afterwards off. so the printer is not detected by the computer and i can’t do anything anymore….
Anyone else experienced this?
December 29th, 2009 at 5:11 am
That RUINED my printer! Every time i want to start it it displays green light for a second,then red light and an “invalid black toner cartridge”message appears.PLEASE HELP ME!
December 29th, 2009 at 2:40 pm
Nice:)
How old does your printer? Maybe new stock firmwares don”t allowe upgrade:( What does it if you push the printer button for five sec?
If you find a solution, please write it! I hope you can solve it!
December 29th, 2009 at 6:21 pm
My printer is relatively brand new,only one month or so.when i press the reset button it printes a page with the printer specifivations,NOTHING MORE!
December 29th, 2009 at 7:44 pm
I am sad, because i have a new ml-1640 too, and i also would like to reset the counter with this method.
Try these methods:

December 29th, 2009 at 10:34 pm
My Printer is ML-2240.Thank you for your interset but try to find a solution to the ML-2240 if you please.
December 30th, 2009 at 12:41 am
@rafa, well: Hi, I’m sorry to hear that it somehow doesn’t work for both of you
I’m not 100% sure why, but things like this happens mostly because printer is disconnected during process or is turned off too early that firmware download was interupted during process.
Honestly, right now I don’t have any info/knowledge of solving this problem, but I’ll look around and inform back here if I can find something.
December 30th, 2009 at 2:32 pm
if you failed to flash go to samsung and flash with the official firmware ( samsung download center ) to fix you printer again
happened to me BUT it didn’t reset the count to 0
any help ??
December 30th, 2009 at 3:51 pm
@stranger: Try this firmware: http://www.webaruhaz.hu/download/doksi/ML1640upgrade.zip
Run Setup.exe and click start button.
The red led will be orange and when it finish it will be green. Then you turn off and on you printer and it would be OK.
This is a patched firmware too, but it’s from a webshop site, so maybe it could work.
p.s.: You should be patient with upgrading, so wait and don’t turn off your printer before time:)
December 30th, 2009 at 4:51 pm
And the firmware for ML-2240:
http://www.webaruhaz.hu/download/doksi/ML2240upgrade.zip
Run setup.exe and click start button, then wait (red,orange,green led!).

SUPPORT IS ON ENGLISH OR SPANISH AND I HAVE THE FIX FOR OLDER FIRMWARE VERSIONS TOO.
December 31st, 2009 at 6:37 pm
Hi again!
@well: So as a realized now your problem is caused by the new stock firmware of your printer.
The older patched firmwares don’t work with new printers.
But now there is a new version (93).
You can download it from:
http://www.startcopy.ru/repair/files/sams48xx.htm
(Use google translate if it needed
)
Or wait for new patched firmware, but don’t forget you need a patched version of ML1640_V1010093.fls or ML2240_V1010093.fls according to your printer.
I hope somebody write a good tutorial for the new versions!:)
ps: Don’t pay for patched firmwares, because you will get it for free!
January 2nd, 2010 at 1:59 am
Still not working.i sent it to the dealer and even him couldn’t solve the problem!
January 4th, 2010 at 6:21 pm
Great! Thanks for sharing! Its work for ML-2240. TQ
January 5th, 2010 at 7:55 pm
my printer ML1640, it stop working after updating
it has no power(led lites one time and off)
January 5th, 2010 at 8:34 pm
Thank you very much brother, it is working successfully on my ML-1640. I am now using the initial catridge now, after patching the initial catridge capacity changes to 1.5K, and the toner remaining status is always in 100% now, the the good thing is the toner page count always remains to zero.
My question is as my printer now recognizes the initial catridge as a full catridge of 1.5K capacity, can I now refill my initial catridge, if yes how? Is the size of the toner compartment small in the initial catridge than that of a full replaced catridge? Please reply. Thankyou
January 5th, 2010 at 10:14 pm
@Ritesh
1. Trun off your printer.
2. Start your computer.
3. Push the orange button, and keep pushing.
4. Then turn on your printer (with the button on the back of the printer). BUT YOU HAVE TO KEEP PUSHING THE ORANGE BUTTON!
5. Then the LEDs start blinking (5-15 sec later), you can release the orange button.
6. You can repeat the firmware installing procedure.
BUT IF YOU DO THE UPDATE AGAIN THE WRONG WAY THEN IT WON’T WORK! PLEASE READ EVERYTHING CAREFULLY!
If you can’t reupgrade the firmware repeate the 6 steps procedure until it won’t work!
January 5th, 2010 at 10:54 pm
Any fix for 1640 firmware version 1.01.00.93? tried all the steps as mentioned above but none work. Did the steps for my other 1640 with firmware of 1.01.00.83 which worked but not for the .93 version
January 6th, 2010 at 2:36 am
Here is the patch. Use google translate if it is need.
http://www.startcopy.ru/repair/files/sams48xx.htm
Please write your results! Thanks!
January 6th, 2010 at 1:11 pm
I have sorted the pins, i get always 0 page count
even after i removed the cable reports 0 count. Now i cannot print at all , red light is on no matter what. I.ve tried http://www.startcopy.ru/repair/files/sams48xx.htm and to downgrade with version 66 . I also flashed with the official 93 version from samsung and still cant get this printer to work
January 6th, 2010 at 7:49 pm
Hi ooppoo!
I can’t upgrade (or downgrade) my new 1640.
After 2100 page printer is stop.
I ned some help for my ML1640 (FW, and reset)
If you can help me, i’ll write my email!
January 6th, 2010 at 9:31 pm
First of all, why can’t you upgrade the firmware? What happen, and which method do you use?
What is the version of the firmware which you use now? Turn on your printer and press the orange button until it start blinking. Then you release the button, it will print a page which contains the firmware version.
But I think, the latest patched version should work if you do everything good!:)
So do the next steps:
1. Download this:
http://www.startcopy.ru/repair/files/ml1640.zip
2. And download this one too:
http://www.startcopy.ru/repair/files/fw_93_84.rar
3. Then unzip ml1640.zip to a folder, than unrar ML1640_V1010093.fls from fw_93_84.rar to the same folder.
4. run fix1640_93.bat. It will make a FIX_ML1640_V1010093.fls file, and give some advice:)!
5. run downl1640_93.bat
6. Please be patiant!
If something goes wrong, please repeat the method which I write down 5 post above!
Any other advice:
You have to remove the chip from the cartridge if it has one before you start downloading the firmware.
January 7th, 2010 at 3:07 am
Is itpossible tot downgrade with the firmware you gave @ooppoo??
I have now firmware 1.29.00.84 so i can dowgrade to firmware V1010093 with the 2 rar and zip file you provided.
Maybe somebody can know this..
January 7th, 2010 at 3:08 am

January 8th, 2010 at 3:47 pm
@somelier: I’m happy to hear your success!:)
@Apoe: Yes you can use the latest firmware too! It’s newer than yours, but you just do an update like you update OS on your PC:) (You can also download new versions from samsung download center…) So you CAN USE this rar and zip!!! PLEASE WRITE YOUR RESULTS BECAUSE IT HELP OTHERS!
January 8th, 2010 at 11:02 pm
Ooppoo, many thanks!! I performed your trick with my ML-1640 v1.29.00.93. Now “toner remaining” is from 100% back to 0%. The total page count remains the same. Cartridge capacity from 0.7K to 1.5K and dot/opc count back to zero (don’t know what that is). I have the starter cartridge in the printer. Is is now just buying some toner and fill this cartridge up? Or?
January 8th, 2010 at 11:19 pm
@jeeest: I not really understand what you wrote.:S You did this hack because you want to refill your toner didn’t you? So why do you want to buy a new one?
January 9th, 2010 at 1:27 am
@Ooppoo
oops
“toner remaining” obviously went up from 1% or so to 100%.

But your printer work, isn’t it?
If not please follow these steps:
1. Trun off your printer.
2. Start your computer.
3. Push the orange button, and keep pushing.
4. Then turn on your printer (with the button on the back of the printer). BUT YOU HAVE TO KEEP PUSHING THE ORANGE BUTTON!
5. Then the LEDs start blinking (5-15 sec later), you can release the orange button.
6. You can repeat the firmware installing procedure.
Now you use the 93 version! If your printer work use the 93 version too.
1. Download this:
http://www.startcopy.ru/repair/files/ml1640.zip
2. And download this one too:
http://www.startcopy.ru/repair/files/fw_93_84.rar
3. Then unzip ml1640.zip to a folder, than unrar ML1640_V1010093.fls from fw_93_84.rar to the same folder.

5. run downl1640_93.bat
January 13th, 2010 at 11:35 pm
@sajid: Try the 93 version!
Look for this post: (ooppoo Says: January 6th, 2010 at 9:31 pm)
January 14th, 2010 at 12:36 am
Hello everybody! I bought a ML-1640 a couple of hours ago after reading here that it is possible to hack it. Thanks guys! OS version: 1.29.00.78 (09.30.2008). Does anyone know wether shorting the pins will work with this firmware or not? It’s new and I don’t want to ruin it on day 0
. Thank you.
January 14th, 2010 at 4:47 am
@pyngi
You don’t need shorting the pins and any kind of hardware hacking. Just install the patched firmware and it is always resetting toner stats every turn on of the printer. Please read this thread and every post in this forum. The best if you use the .93 version…
January 14th, 2010 at 6:20 pm
Hi guys. I see you wrote some useful stuff in here.
I do have a problem tho, I have ML – 1640 printer (brand new), with 1.01.00.91 firmware (havent seen .91 firmware till now)
Anybody knows how to downgrade it to .83 or lower? preferablly to .66.
Version .93 is the last version Samsung put out, its also a version you cannot downgrade as far as I know. Is it the same with .91?
I’ve tried to flash it with my .66 firmware
and tried the simple pack with .83 version. none work.
any ideas?
January 14th, 2010 at 8:12 pm
@palin: Why do you want to downgrade, hm?
You just use the patched .93 version which I linked above, and please follow my instructions. With this patched .93 version firmware you can refill your toner. More over you can use bigger toners. i.e.: 1610 (3000 pages).
We downgraded the firmware, because newer versions don’t let you short pins. So we needed to downgrade to older versions which let you short the pins. Then Samsung made a newer firmwares which don’t let you short pins and unfortunately we couldn’t downgrade because new firmwares deny downgrade. So now we can upgrade. And clever hackers make a patched firmware from the .93 version. And it’s the newest one, so everybody can upgrade to it. It is patched which means it isn’t the stock firmware because, it always reset toners counter without you needed to short the pins.
So please use the version 93 patch from the russian site.

cyellenhans: Hai, salam kenal juga, justru saya awalnya mencari cara ini karena kami terlanjur membeli toner refill tapi tidak membawa printernya ke supplier, sehingga saya harus cari cara agar toner itu bisa dipakai tanpa harus membawa kembali printer ke supplier. Jadi jawabannya tidak perlu di bawa lagi printernya
January 15th, 2010 at 12:46 pm
thanks ooppoo..you solved my 1640 printer issue.. u guys doing good job..now my printer working with refilld cartridge,paper count starts frome zero..thank you so much..
January 15th, 2010 at 1:43 pm
ooppoo thank you, i will try that now.
The point is i’ve fucked the printer of one of my customers – he wanted to use recycled cartridges and i put .93 samsung firmware on it and nothing helped after that.
going to try the russian firmware.
January 15th, 2010 at 11:29 pm
Thanks kocu! I hope it makes easier to find the important information among many replies!:)
January 17th, 2010 at 12:42 am
@ooppoo: You are the king! I did everything as you said and it worked. Here are the changes:
Before hacking / after hacking:
Ram Size: 8 Mbytes / 8Mbytes
Total page count: 9 / 11
OS version: 1.29.00.78 / 1.29.00.93

Toner status: Normal / Normal
Initial Toner Page Count: 10 / 0
Cartridge capacity: 0.7 K / 1.5 K

Catrtidge S/N: CRUM-INIT_TONER / Not Support
Supplier: / SAMSUNG (INI)
Manufacturing Date:200801 / Not Support
I have 1 observation though: It’s not very clear from your instructions that you have to turn on your printer from the button from the back while pressing the orange button until the LED starts blinking. First I turned it on then pressed the orange button, got the test page started flashing but the orange LED kept blinking and nothing happened. THANK YOU anyway great job!
P.S: Why are manufacturers allowed to do this kind of things in the first place? It is not very eco-friendly to throw away cartridges that can be recycled couple of times.
January 17th, 2010 at 1:09 am
“More over you can use bigger toners. i.e.: 1610 (3000 pages). “@ ooppoo: Is 1610 toner compatible with this printer? Does it fit? Is it recognized? Thanks. I still can’t believe I’ve done it
January 17th, 2010 at 2:58 pm
@pyngi
The orange button:
If your printer turned on and you push the orange button until LED start blinking –> you print a test page.
If your printer turned off and you push the orange button and while keep pushing it and turn on your printer with the button on the back of the printer, than you release the orange button when the LED start blinking –> hard reset, the printer ask the firmware. You should use it when you fail with uploading the firmware, or your printer doesn’t work.
I never use 1610 toner with ML-1640, but as I know you can use it, you just have to remove or use cellotape to stick the chip on the toner.
(Sorry for my bad English:))
January 17th, 2010 at 6:20 pm
Thank you for your answer. As far as I know 1610 toner doesn’t have any chip. I’ll try to do a research on it. Anyway I have the time because the printer is new only 13 pages total. Great work anyway and thanks again.

most of them have recycling programs, its just that people mostly dont care bout it.
January 20th, 2010 at 11:03 pm
I have an ML-1640.
I tried OOppoo’s first (Jan 6, 2010; 9:31 p.m. post) because it’s newer. Step 3 said running fix1640_93.bat “will make a FIX_ML1640_V1010093.fls file”. It created two files instead = fixml40.exe and ML2240_V1010093.fls. The content of fix1640_93.bat does say “fixml40.exe ML1640_V1010093.fls; pause 0 .”Then, on the CMD window, it said “Error reading input file!”
There were two fix1640_93.bat files though, one in the main folder and other in “ignordev” subfolder (I unzipped with “use folder names” checked). I used the one in the main folder. Should I have used the one in the ignodev subfolder?
I then tried the Simple Package in Kocu’s blog. It worked for me. Here’s my test page (before –> after):
Total page count: 28 –> 29
OS version: 1.01.00.84 05-13-2009 –> 1.01.00.83f 04-08-2009
Enginer version: 1.00.50 –> same
SPL version: 5.07 06-27-2006 –> same
Service date: 2010-1-13 –> same
Toner page count: 29 –> 0
Toner remaining: 92% –> 100%
Toner status: normal –> same
Initial toner page count: 29 –> 0
Cartridge capacity: 0.7K –> 1.5K
Dot/OPC count: 90275280/352 –> 00/0
Cartridge S/N: not support –> same
Supplier: Samsung(INI) –> same
Manufacturing date: not support –> same
Thanks to everyone for all the information you’re shared!
I have a question though. What’s the difference between firmware 1.01.00.83 and 1.01.00.93? Is there an advantage to using the later firmware/patched firmware? I’m asking because I’m wondering if I should still spend time trying to install a patched version of 1.01.00.93.

Hi,
I’ve seen now may tonners came with a chip themselves. I’m wondering about how the firmware patch will behave with such a tonner. Does anyone have an experience to share?
Regards.
January 23rd, 2010 at 6:07 am
Thanks for posting this
ML2240 now working perfectly again, without toner carts that cost as much as the printer!!
Cheers
January 24th, 2010 at 4:15 pm
thanx 2 all of you. today i fixed my office’s 1640 with the initial cartridge. but i had already bought a replacement cartridge, regarding which i have some confusion that, will i be able to use that replacement cartridge, after i have done this f/w upgrading thing, just putting it in the printer normally if necessity rises to use this one. though my initial one is working after the reset.
please suggest, if anyone have any experience regarding this type circumstance.
January 24th, 2010 at 5:08 pm
Try using scotch tape or insulating tape to stick the chip on the toner. As result it will be the same as the initial toner.
January 26th, 2010 at 10:47 am
thank u. i’ll let u know of my exp regarding this matter.
i never despair, coz still this earth contains some such or other unidentified good souls who can think beyond business or personal profit.
January 27th, 2010 at 9:11 am
Hi Kocu!

January 27th, 2010 at 3:43 pm
Hello.
I just bought new toner (the one with chip) and I have firmware for my ML 1640 updated to .93. (Before that I had .60 version so I could have printed more pages with the initial toner, but I updated it now with the firmware from Russian site with hope it will solve my problem.) I’ve tried insulating the chip but I still get the message “Invalid Black Toner Cartridge” and “Supplier: Invalid Toner”. What should I do – can anyone please help me?
January 27th, 2010 at 9:12 pm
Hey!
There is a nice tutorial from the original russian page of the patched firmware
(please use google translate):

January 27th, 2010 at 9:48 pm
rusian link works, shifty samsung thawthed
January 27th, 2010 at 11:48 pm
it’s work boss!
thanks a lot!
January 28th, 2010 at 4:11 am
As it seemed I had to do the following:
- Install cracked firmware .93f
- I have a new toner with a chip so I had to stick some tape over the chip.
Thanks again folks!
January 28th, 2010 at 11:01 pm
I am glad that it worked for all you. Unfortunatelly after some FW upgrade I have the printer led always blinking (red/green/red/green/…).
What can I do to make my printer come to live again?
First I made the Simple version and after that I can’t print a seft test page. Then I decided to try the RAW version and the blinking led problem happened
Thanks a lot.
January 28th, 2010 at 11:17 pm
Solved!
I did what ooppoo said in
«ooppoo Says:
January 5th, 2010 at 10:14 pm»
The FW can be updated even having the led blinking!
Thanks all!
January 29th, 2010 at 5:39 am
thanks !
not so easy to upgrade but it worked.
you should mention that it works with cartridge without chip or with scotch on it.
otherwise the counter remains the same .
thanks again.
January 29th, 2010 at 5:45 am
gracias por este metodo me funciono a la perfeccion el ml-2240 solo que no me quedo a la primera pero la segunda vez todo bien.
January 30th, 2010 at 8:46 am
I tried this:
i have an initial toner that reads 1.5k max (because of the simple patch above) and i tried using ML1610 toner. basically it won’t work. but the design is just identical. What I did is, i removed the cover of both toners (initial ml1640 and ML1610 toners) and inter-change them. I plugged in the ML1610 with ML1640 cover and presto, it worked!
i don’t know if it will work on every ML1640 toner coz i only 1 have piece of it. but you could try and post the result here. goodluck.
January 31st, 2010 at 12:31 am
Hi There!
Just to let you know that I did exactly as ooppoo said in his commnet highlithed in red and worked perfectly.
Firmware update took about 5 secons, and 5 seconds later the printer seemed to reset itself (red light turned to blinking red for a while and made some paper tray sound, just like when you turn it on). Then back to green light and was ready to go.
FYI. My original firmware was 1.01.00.91 and patched version shows 1.01.0093f
“Intitial tonner page count” resets to zero every time I power off the printer and “cartridge capacity” has been upgraded fromm 0,7K to 1.5K.
Needless to say Sahat and Ooppoo are the greatests !!!!!!!!!!
February 1st, 2010 at 2:41 am
I’ve tried with a ml-2240 but by mistake i used fix2240_93 altought the original firmware was 1.01.00.84 … the download was fine but the printer says the toner is empty… Reading the russian page says that i must use fix2240_83 but a i can´t go back… i’ve tried to install the original firmware but the printer stays with the 93f again… any idea?
February 1st, 2010 at 8:11 am
I did it!!…. Because i have an original toner only, i put a tape on the chip but the other thing i was missing was the fuse… i put a fuse then aplied de 93f and it erased the counters… its working fine thanks to all… hope this helps.
February 3rd, 2010 at 1:56 am
Hello , this is zohaib , and i wanted to buy a laser printer , and i have been reading this blog and

February 6th, 2010 at 2:08 pm
hi sir, ihave samsung ml 1640 os version 1.01.00.84 iwas tried above software but the printer does not reset the page count & red light blinking now. please help me!
February 7th, 2010 at 1:50 am
HELP!!!!
When you get to step 4 (from the red highlighted instructions) it says the following:
4. run fix1640_93.bat. It will make a FIX_ML1640_V1010093.fls file, and give some advice:)!
I did this and a black DOS looking window pops up on my screen with the following instructions:
1. Remove chip from cartridge.
2. Download file “FIX_ML2240_V10100093.fls to printer by usbprns2.exe or usblist2.exe.
3. If “?Device Emplty” jumper closed all counters except “total Page Count” will reset after each powere on. If “DEVE” jumper open all counters behavior equal to original firmware. Cartridge capacity increased from 700 to 1500 pages.
OK….. so… I have the initial cartridge that came with my new printer. I don’t have a chip in the cartridge. Is this going to work? Also, when I downloaded file “FIX_ML2240_V10100093.fls” …what does it mean by dowloading it by usbprns2.exe or usblist2.exe??? I clicked to download it and I didn’t know what do do next b/c my computer didn’t have anything to download it with and windows did a search and couldn’t find anything.
February 7th, 2010 at 2:24 pm
Hello
for ML2240 I use simple pakage it finished in a moment BUT now windows can not recognize catch my printer e.g. it’s no responding to plug play, the Toner led is ON my os is XP SP3

February 7th, 2010 at 8:33 pm
Hi,
I used Simple Package for ML-2240 to overcome Toner Exhausted problem, It finished in a moment. I turned OFF printer and then ON. now only Toner led (RED) is ON, power led blinks in a few second interval. I tried Trund ON power while OK button is pressed and Pressing OK button for a while result the Power button to Blinks Yellow-Green-Yellow it does not stop till Power OFF.
BIG problem is this printer is not being recognized by XP, new harware wizard failed to detect the printer! any suggestion will be highly appreciated..Thanks
February 8th, 2010 at 10:22 pm
Dear All, I’m really really sorry for not being able to answer each of your question personally. But please notice that this fix should work.
If you need a newer firmware version please look at a comment posted by ooppoo which I’ve marked in red.
If your printer go bad and somehow become unusable, please look at a comment posted by ooppoo which I’ve marked in bright red.
Cheers
February 9th, 2010 at 2:43 am
Hi!
One thing which could cause problems to anybody:
When you start download bat, it’s open a cmd window. Then it puts some dot to the window, then it says downloading finished. And you have to press a button, then the window’ll close! BUT THE FIRMWARE UPLOADING START AFTER YOU CLOSE THIS WINDOW!!! SO YOU SHOULD WAIT!!! I AM SORRY BUT THE “FINISHED” MESSAGE IS WRONG AND THE DOTS DON’T SHOW THE REAL PROGRESS OF THE FIRMWARE UPLOADING.
February 10th, 2010 at 9:39 am
thanks atas info2 di website ini, kemarin saya sempat update firmware ml 2240 dengan ML1640_V1010066.fls dari 1640, mengakibatkan printer saya nyala warna merah, dan tidak bisa digunakan untuk print meskipun di status printer windows adalah ready. untuk print informasi printer langsung dari printer nya saja tidak bisa. lalu saya coba jalankan program firmware downloader (downlXX40.bat). akhirnya printer normal lagi..
os berubah dari 1.01.00.77 07-30-2008 menjadi
1.01.0083f 04-08-2009
initial toner pagecount nya menjadi 0 lagi..
thanks all
February 11th, 2010 at 3:06 pm
Hi guys!
I had the same problem with the Samsung ML 1640 printer. First I tried to follow the steps written by ooppoo with red color, but it didn’t work for my printer. Then I just used the Simple Package for ML 1640, and my problem was immediately resolved! Now my printer is working propperly again (with the original cartridge).
I really appreciate and thank your help!!
February 12th, 2010 at 10:35 pm
bang sahat, saya baru beli samsung ml-2240 dua hari yang lalu dan baru coba print beberapa lembar. haruskah saya mengupgrade firmware nya sebelum habis toner asli apa harus menunggu sampai ada notofikasi isi toner habis?? btw, kalo mo lihat versi firmware dari mana yah? trims infonya…ditunggu yah ngak pake lama.
February 12th, 2010 at 11:08 pm
alow mas dayan, sebaiknya tidak perlu diutak atik dulu printer barunya, nikmati saja dulu
kalau nanti habis dan mau refill lebih baik tanyakan apakah supplier toner refill nya bisa membantu, karena biasanya mereka berani memberikan garansi. Kalau memang tidak ada baru saya sarankan jalankan update firmwarenya 
untuk lihat versi firmware caranya tekan tombol printer sampai berkedip lalu lepaskan
February 13th, 2010 at 12:53 am
weleh2 trims yo, saya udah nanya waktu beli kmaren, bisa refill ngak? katanya bisa, bawa aja ke toko (130rb). sippp… saya nikmatin dulu aja toner aslinya, sampe keluar tulisan” ganti toner” hehe. nanti kalo saya kesulitan boleh lah tanya2 lagi. trims lagi yo… sudah banyak membantu orang lain. semoga banyak berkatnya.
February 13th, 2010 at 4:37 am
Please help! I bought ML1640 printer and it has 1.29.00.93 firmware. But I can’t find there to download this original firmware in order to patch it. Samsung site doesn’t have downloads for firmware. What can I do? Thanks!
February 13th, 2010 at 3:24 pm

February 13th, 2010 at 10:33 pm
Tick: Hi Tick, you don’t have to download it again, just download between the simple or raw package and run the steps, or you can also try the download link suggested by ooppoo which I’ve marked in red
Vivek: Hi vivek, did you download the raw package and tried to run the original firmware updater from samsung? Please follow the full instruction or just try the simple package instead
February 13th, 2010 at 11:27 pm
kocu, thank you for answering and supporting this thread!
Thanks!
Till now I thought I need to patch exactly the same firmware version I have in my printer, but now I see how it works
And one more question, Will I have the same version as before patching or I will downgrade it to V1.01.00.93?
February 14th, 2010 at 1:37 am
Hi everyone,
I have used ooppoo’s method (comment from January 6th). It has worked perfectly on my ML-1640 with OS version 1.29.00.93 11-23-2009. I am now printing with a refilled toner cartridge.
Thank you all so much for your help!
February 15th, 2010 at 10:23 pm
Hi Grits. I’m replying to your post of Feb.7 regarding the instructions that appear int the DOS box when you run run fix1640_93.bat.
Disregard that information and go ahead with the patch.
Take care.
February 16th, 2010 at 6:04 am
Hello,
I have just bought the mL-160 series today with the firmware OS version of 1.29.00.93 . It has the original starter toner. which steps shopuld i follow? the one at top of page or OOPPOO’s method? Pleas4e help
Thanks
February 17th, 2010 at 2:28 am

Hi guys..,
Saya baru beli ML1640 dgn OS version 1.01.00.78. Saya sudah terlanjur menghacking hardwarenya (pasang chip/cara tertentu) supaya toner page count ke 0. Bisakah saya lepas kembali alat tsb kemudian saya upoading firmwarenya (93). tengkyu
February 17th, 2010 at 11:13 pm
Tick: Hi again Tick, sorry for late reply. If you use my version then you’ll be using older firmware version, if you use firmware from ooppoo link then you’re using same firmware version
suzy lcd: Hello, if you’ve just bought your printer, there’s no need to do any firmware upgrade
enjoy it first. Come back when you want to refill the toner and you don’t get any support from ur supplier 
Allvhan: Hi jg, kalo udah terlanjur di hack secara hardware dan bisa berjalan dengan baik saran saya sih lebih baik biarkan saja
February 22nd, 2010 at 7:58 am

I have one small question
Initial toner page count reset to zero but total page count is still showing 303.
Is there any problem with Total page count?
February 23rd, 2010 at 6:40 pm
No the total page count won’t be zero. But it’s not a problem.
“Toner Page Count” and “Initial Toner Page Count” should be zero on every turn on. And “Dot/OPC count” also should be zero.
February 24th, 2010 at 2:03 pm

Any help for Linux users?

@Guiseppe: There is no linux version of the firmware uploader software. So you should get a windows. I don’t dare to try the program with wine!
@Tom: I don’t know. But you can try it!
Nothing wrong can happen. You just upload the firmware without the FIX.

My printer ML1640, it stop working after updating
it has no power(led lites one time and off)
And I’ve tried the all the step that oopooo said above :
1. Trun off your printer.
2. Start your computer.
3. Push the orange button, and keep pushing.
4. Then turn on your printer (with the button on the back of the printer). BUT YOU HAVE TO KEEP PUSHING THE ORANGE BUTTON!
5. Then the LEDs start blinking (5-15 sec later), you can release the orange button.
6. You can repeat the firmware installing procedure.
But, when I try until the step 4 above, there’s nothing happen with the printer, it doesn’t blink at all (I’ve already hold the orange until 1 minutes). And until now, the printer still off.
Does anyone could help me?

perfect.
I used the simple package for my ML-2240 that stopped to print during my job. It was very easy and quick. I waited 30 second before closing the windows, at least after a sound from the printer. I waited other 30 second before turning on the printer.
Now it says:
OS version: 1.29.00.84 05-13-2009 > 1.29.00.83 04-08-2009
toner page count//: 2090/0(%) replace toner > 1/100(%) /normal
A question: which is the main difference with the OS version 1.01.00.93 ? the simple package is so easy to instal….
A lot of thanks to Koku and Oopooo

Works great.
os version is now 1.01.0093f
just follow ooppoo’s post. make sure you WAIT before you close the download screen. after 5-10 sec your printer should make some noise and light will turn amber then green then you can close it.
