When you encounter a squeaking bushing, replace both bushings.
The replacement bushings must securely engage the ground plane to
avoid static build-up.
PROBLEM: SQUEAKING DURING PRINTING DUE TO DRY BUSHINGS
A small number of printers may start to produce a squeaking noise
during printing due to defective bushings installed in the printer's rightside frame. The bushings will likely fail (squeak) early in the printer's
life. Most likely within less than 1,000 prints. The problematic bushings
are only installed in the right-side frame and support the take-away
roller shaft and the duplex-roller shaft.
Take away
CAUSE
roller bushing
If the noise persists after replacement, the shaft may need to be replaced
The bushings in question were not impregnated with oil by the bushing
vendor.
(due to the printer being used for a long time with the defective
bushing).
NOTE
: A special process is used to impregnate bushings
with oil. Simply applying oil to dry bushings will not
adequately lubricate them.
PARTS INVENTORY STATEGY
Two 6mm, oil-impregnated brass bushings are available in a new
