Any ideas, screenshot attached. Any ideas? Tried boards (HV 1 & 2, PRCB, MCB, Power Board), laser, IU's, Fuser, T-Roller, T-Roller Pressure/Retract Unit, Cleaning T-Belt Contacts, T-Belt! :mad:

It could be a fusing speed problem.
The first suspect would be the loop amount detection sensor 1/2 and the actuator.

A colleague of mine had this problem, swapped EVERYTHING (except the thing that solved it), like you.
Finally, he replaced the EEPROM and the problem went away.

Thanks for the replies... can you tell me what EEPROM you mean? The NVRAM? Thanks, Dave.

The one responsible for the color calibration, behind the shield box... Don't know what it's called, even KM here in Sweden just call it EEPROM... :p

Wow! The first thing I would have tried was the cyan drum.
