WIC Reset Program and Chipless Firmware

Epson P800 firmware update fail

Recommended Posts

I have tried 3x to install the chipless FW to our P800. It reached 95% before failing, then 14%. I have unplugged and restarted the printer but so far no success. The printer has an "unrecognized cartridge" error from a 3rd party cart that has gone dry. Can the firmware be installed in maintenance mode, and how can I access that? Any help is greatly appreciated!

Update process is complete - printer will restart - usually it will take only a few minutes but can continue for 10-20 minutes in some rare cases. 
If process hangs or stops at 80-99% - replug power cable and start printer manually.
