Hi

The tech manual I have says that this is an issue with the transfer belt.

Suggestions are:
1)Check connectors CN409 & CN407 on sensor board
2)Check connectors CN26 & CN29 on printer controller board
3)Remove transfer belt & check that the belt up/down sensor flag is properly installed & not broken, and that the sensor and its connector are in place
4)Clean belt up/down sensor
5) Test that the up/down sensor works by actuating the sensor and monitoring the voltage between pins 8 & 10 on connector CN29. Replace if necessary
6)Replace belt up/down clutch
7)replace printer controller board.

This is on page 2-20 of the Service Manual for the Lexmark C910 (5055-xxx)


Hope this helps
