I was doing factory reset on a Lexmark MC3224dwe printer and during the reset the power cable got disconnected (not intentionally). As a result, I am getting a blue screen with the following error:
Firmware Error [900.00] Problem with restoreBuffer idx 1, stat -5, setting 0x2001, error 14. /usr/bin/hydra:1023:hydra
Printer starts booting, draws the logo and ends up with the same error screen:
I've contacted the manufacturer - their quote to fix this issue is 95% of what a brand new printer (same model) costs.
Is there any way to do a hard reset? Is it NVRAM I need to reset? This model has no keyboard, so it looks like magic instructions from the internet (hold 2+6 while booting up etc) don't seem to apply here.
The model has one physical button (top right corner on the picture), an Ethernet port and a USB-port (PC doesn't see any device when I connect it via USB. Didn't try to connect via Ethernet).
There is a yellow jumper on the motherboard, I've tried changing its position, no effect.
