For starters, I think I would re-seat all the connectors for the laser, PRCB, and MFP board. Then see if anything has changed. =^..^=

Then see if anything has changed. =^..^= Dear blackcat4866, I have re seated all the connectors as you suggested and i found one of the two flat cables of the print head unit is damaged could that be the problem? and could that lead to machine rejecting the flash drive as well the lines on lcd? also i have noticed the failure when i check memory to printer in state confirmation in service mode. By the way the problem still persist and there is no slight change. Best of regards, Ahmed.

I agree with Blackcat this is definitely looking like a PH or MFP issue. Tough to tell on example, are those lines different colors or 1 color? if they were different colors I'd say you could rule the PH right out and think MFP.

Re-seat memory chip(s) on MFB board also.

Had a c280 do this some time ago.
It was the mfp board.

if the damaged part of the end is not too long, just trim it off square with very sharp scissors. your test print looks like the cable is the cause. good luck!

This has worked for me a few times. It depends on how much of the ribbon is damaged. You've got nothing to lose now. =^..^=
