Before you continue with the reprogramming of the firmware, please make sure that the device is installed on your computer.
It is very important that under no circumstances should you remove the chip from the cartridge while reprogramming the firmware. After you have succesfully reprogrammed the printer, remove the chip from the cartridge and store it somewhere safely (the chip - a key). In all cartridges which you are going to use in the printer, the chip has to be either removed or sealed. If you have accidently inserted a new cartridge without removing the chip, the device will be blocked. In order to unblock it, you can use the stored chip as a key which help you to unblock the printer.
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 printer to the computer and turn it on
2. Wait until the printer is ready for work
3. Run the file "download.bat"
4. The reprogramming process starts automatically
5. Wait until the printer reprograms (5-15 minute) and restarts
6. After that the reprogramming process is finished, restart the printer
In CRUM field please enter any not testing cartridge CRUM number. So to fix your printer you need have in printer at least one new original cartridge (any color).
