Firmware Samsung SCX-4623FN (MD)
Before you continue with the reprogramming of the firmware, please make sure that the device is installed on your computer. Remove the chip from the cartridge or seal it up. And make sure that any other devices (except mouse and keyboard), which are connected to your computer via USB or LPT ports are disconnected. It’s preferable that the computer is connected to the "UPS" (uninterruptible power source) device, because if during the reprogramming process the electricity source has any interruptions, then the reprogramming will be carried out with an error, which makes the device unable to work.
Be aware that with the reprogramming of the firmware the manufacturer’s warranty goes lost!!
1. Connect the device to your computer and turn it on while holding the button "Stop"
2. "Download mode" appears on the display
3. Click again the button “Stop” on your printer
4. After that, on the small screen should appear "wait image1"
5. Then run the file "fix4623.bat"
6. When this file is run, a file is created in this folder "FIX_SCX4623FN_V2.01.00.93T.hd"
7. Drag that file on the file icon "usbprns2.exe"
8. When it’s done, the reprogramming begins automatically (5 min) and afterwards the device restarts
