Bizhub-350 monochrome, print button flashing quickly amber.

Machine was working OK until one of my techs replaced rollers in port #2. from than on we had service code C-3751, message "Install Drumunit" and other weird behavior.

What we did until now, not out of believe but out of dispair:

New firmware, total reset, replaced PWB A, MFBS-board, Power unit.

What we did not yet do:

Use the POS as a boat anchor.

What am I overlooking? Any ideas please?

Roll it off the dock into the dumpster...

Did you try replacing the fuser too?

Flashing Amber usually means the machine was left in Service Mode 2, or corrupt firmware. But since you say this happened after servicing Tray 2 feed section, I would remove the bypass assembly and inspect the connectors for bent pins, damaged, pinched or broken wires.

For sure its must be something like a pinched wire or disconnecting connector under power. That was the first thing I looked for but didn't found something. Than I installed the firmware and than I started changing boards. Still no solution. Since the machine has one million and is of an older generation I will scrap it. But I would buy a beer for anyone giving me the solution. Just for shits & giggles if you got what I mean.
