Chapter 4 Failure & Repair Analysis
4.4.04 Audible Roller Noises
NOTE: The information in this section is also covered in TSB 5608 / FCO 8126 .
Symptoms
The unit "squeaks and squeals" whenever the rollers in the unit are turning.
Cause
The copper frame ground clip of the fuser pressure roller requires lubrication.
When viewing the printer from the front, the clip is on the right hand side.
Solution
Lubricate the clip.
To access the clip, disassemble the unit to the fusing unit assembly.
Refer to Section Three of this Service Handbook for disassembly information.
Apply a very small amount of Dow Corning Molykote HP 300 grease to the face of the
ground clip, where the clip contact the fuser pressure roller.
DO NOT OVER LUBRICATE. Excess lubricant will attract toner and could cause problems.
Assemble the unit.
Okidata FCO Kit 8126 (P/N 58235401) includes the grease and instructional diagrams. Each kit
contains enough grease for many applications.
