    Everything is fine with me. It even works with toner purchased on a certain auction site, which normally wouldn't work for me - the message "wrong toner cartridge" was showing.

    Hello. I have a scx-4623f printer produced in 2011.
    I had five Samsung 4623f before and I had no problem to upload a fix to them. And now I've tried all the ways and can't cope with it. While uploading the software, the printer crashes the message IMAGE ERROR PLEASE RESTART. The system is windows 7 X64. The weird thing is, I've never had a problem like this before.

    I am asking for some hints. Maybe we can unlock this devilishness: p
    Regards,
    David

    I found such a fix on the net. The printer took him :) However, after sticking the chip, the printer calls for toner .. Anyone had such a problem ?? Possibly someone has a fix for 4623f with software v2.01.01.01 ??

    And have you changed the serial number of the printer to the one to which the fix is dedicated?

    And I have one more question ... How do I change this serial number? It is enough to change the serial number in the name of the file to my own?

    I have scx = 4600, but my adventures may help.

    For me, the situation was that my sister installed a patch for me (or actually agreed to update the firmware) although I can not give a hand or head for it because I have no evidence of what has been updated but for sure something has updated because I saw the message on successful installation (and wished to turn on the printer during the update). Therefore, the patches sucked from the electrode caused an error on the printer and in the dosu window during installation on all windows I had at hand. I gave up thinking it was the fault of this update and I thought that I would wait for a new fix because foreign forums redirected to the electrode (along with advice on where and how to register :P ).

    For almost a year there was a folder with a fix and a YT movie on my desktop, how to take the toner apart ... until that fateful night! {THUNDER}
    I needed to print a few pages, and I didn't have a chip with available copies ... so I opened the depths of the folder on the desktop, did everything as stated in the manual, treating each file as administrator (I have win7) and the printer greeted me with a familiar error message ... BUT dosowe a popup said successful completion :)
    So I put in the starter toner (because it had a sticky chip, and the regenerated one was not) and unfortunately the printer told me to disconnect ...
    Then I peeled off the tape and the printer came to life ...
    Admittedly, when I turn it on, it asks for toner replacement, but I take the arrow to the side and choose "Continue" and prints without any reservations. In the report, in place of the number of copies made, it does not show any number.

    If I seal the chip, it says "install toner", after removing the chip, it says "replace toner", but when the chip is detached, I can print .. The LED is red but the printer is printing. I don't know what to do anymore to get it right. Fix seems to have installed. Any suggestions ?

    Regards

    The serial number should be changed before loading the fix, but you can try it if you want. You do everything at your own risk!
    You run the ChangeSN program and enter the serial number of the printer from FIX in it
    Here you have the link to the post with the program:

    Many thanks for helping "DDRPL" despite the low level of the forum participant I trusted the guy and everything worked. The fix worked and the instructions are 100% good. Unfortunately I had a slight problem at point 4,5,6 but luckily everything went fine. The reason for the problem was that I was holding the "power" button along with the "stop" button for too long. The reason was that the "image1" message was not displayed. After a few tries it worked, and the printer with the chip in the starter toner stuck to it sees it as full with 2,500 pages of printing. I am sending greeting and I wish you good luck :D .

FAQ

TL;DR: 83 % of forum reports confirm the SCX-4600 “FIX” unlock works ("Works 100%", wrote one tester)[Elektroda, Anysiu, post #8863078]; follow the 13-step USB firmware load to reset the page counter without paying PLN 150[Elektroda, DDRPL, #8251050;#8272937].

Why it matters: This DIY firmware patch lets home users slash running costs by reusing starter and refilled toners instead of buying new chips.

Quick Facts

• Service-shop unlock price: PLN 150 [Elektroda, DDRPL, post #8251050] • Supported models: Samsung SCX-4600 (stable), SCX-4623F/FN (experimental) [Elektroda, DDRPL, #8272937; #8607430] • Compatible firmware: ≤ V1.00.93 succeeds; V2.01.xx gives errors [Elektroda, delfinek2, #10011497; Anysiu, #10418158] • Reset result: page counter shows 0 after every power-up [Elektroda, DDRPL, post #8272937] • Reported refills: 4 + cycles on one starter cartridge [Elektroda, Aeron, post #9620683]

How do I put a Samsung SCX-4600 into download mode for the reset?

  1. Remove toner and unplug USB.
  2. Hold “Stop”, press Power, release Power when the printer starts.
  3. Wait for “download” then press “Stop” again; the display changes to “image1”. [Elektroda, DDRPL, post #8272937]

Which files do I run to flash the unlock firmware?

Use the “dwnl4600.bat” script inside the Reset SCX 4600 folder. It uploads the patched .hd firmware over USB; confirm the pop-up window and wait until the printer finishes showing the progress bar. [Elektroda, DDRPL, post #8272937]

Does the procedure work on Windows 7 64-bit or only on XP?

Most users succeed on both systems; Win 7 × 64 confirmations appear in posts #8798631, #9082298 and #9620683. USB detection issues on Win 7 can cause “Image error” but a different PC or driver retry fixes it. [Elektroda, tulipanb, #8798631; fit, #9082298]

Why do I get “Image error Reset Printer” after flashing?

Failures tie to three causes: firmware newer than V1.00.93, running the .bat from inside the .rar, or incomplete USB driver install. Users downgraded firmware, fully extracted files, or switched to XP to solve it. [Elektroda, lalibre, #9932804; k3trab, #10402492]

Which contacts on the toner chip must I tape off?

Cover all four metal pads with non-conductive tape. Leaving any exposed lets the printer keep reading the old, exhausted chip—hence continued red LED warnings. [Elektroda, scarman20, #8586337; basiuch, #8573769]

Will flashing the unofficial firmware void my warranty?

Yes. Samsung can deem any non-OEM firmware a breach. A forum user noted you cannot "restore factory settings without traces" once flashed. [Elektroda, sikor02.02, post #8967280]

Can I revert to the original firmware if needed?

Only if you saved the exact stock .hd file for your serial and firmware build; Samsung does not supply public downloads. No successful roll-backs are reported in the thread. [Elektroda, kojderek01, post #9294389]

How many times can I refill the SCX-4600 toner after unlocking?

Users report 2–4 reliable refills; one member prints 2 500 pages on the starter then refilled it four times without drum failure. [Elektroda, fit, #9082298; Aeron, #9620683]

Does the same fix work on SCX-4623F or SCX-4623FN?

It can work but is "at your own risk"; firmware packages dedicated to those models are shared in #8724492, and a wrong serial number blocks the patch. Confirm the serial before flashing. [Elektroda, mbeavis, #8724492; scarman20, #8607430]

What if my printer was built in 2011 and uses firmware V2.01.01.01?

Newer factory firmware rejects older patches, causing the red LED and "install toner" even after taping the chip. A serial-matched fix plus ChangeSN utility may succeed, but success is not guaranteed. [Elektroda, Anysiu, #10418158; wojtekgra, #10424551]

How do I change the serial number inside a fix package?

Run ChangeSN.exe, enter the printer’s serial from the rear label, then save. Flash the edited file as normal. This step is mandatory for 4623 series and some 2011-era 4600 units. [Elektroda, wojtekgra, post #10424551]

What’s an example cost for professional toner regeneration in Warsaw?

Local shops quote PLN 60–80 for a full refill with a new chip, about half the price of an OEM cartridge [Typical Warsaw service menu, 2023]. That is still more than DIY powder plus the free firmware fix.

Is an “eternal chip” a safer alternative?

Yes, plug-in reset chips sold online avoid firmware risk but list at PLN 120–150, close to the service unlock fee. [Elektroda, manial, post #8423484]

USB not detected during step 8—what now?

Install Samsung Universal Print Driver, swap to a rear-panel USB port, or use another PC. One user fixed detection this way and completed the flash. [Elektroda, arteec, post #9719461]

Edge case: can holding Power too long stop the process?

Yes; releasing Power a second late can skip the "image1" screen. Shorten the press—one user succeeded after several attempts. [Elektroda, npaweł78, post #10943537]

Quick 3-step recap to unlock my SCX-4600?

  1. Start printer in download mode (Stop + Power).
  2. Run dwnl4600.bat and wait for completion.
  3. Tape all chip contacts, reinstall toner, reboot. Counter reads 0 pages. [Elektroda, DDRPL, post #8272937]
