Cleaning and Maintenance
3.
Remove the paper-feed module as explained in the Section 8 topic
“Paper-feed module” on page 8-5 to gain easier access to its rollers. With an
alcohol-dampened cloth, clean the following:
n
Three black rubber feed rollers
n
Two alignment rollers
n
All sheet metal surfaces
4.
Reinstall the paper-feed module.
5.
With a 90% isopropyl alcohol-dampened cloth, clean the lower paper-eject
rollers.
6.
Remove the front top cabinet panel to access the upper paper eject rollers;
clean them with an alcohol-dampened cloth.

With an alcohol-dampened cloth, gently clean the drum. Use side-to-side
strokes. Rotate the drum as you clean it.
8.
Clean the transfer roll mark sensor's white reflection plate with an
alcohol-dampened cloth.
Lubrication
In general, all of the printer's bearings and motors are lifetime factory lubricated.
However, over time and under certain extreme operating conditions, oil and grease may
dry out causing squeaks and rumbling noises in the printer. Look for fine metal particles
– a clear sign of an old or worn bearing. Replace the bearing or the component it is a part
of.
A drop of oil or grease on a noisy bushing will quiet a noisy printer. Too much
lubrication can get into the paper path and attract dust, so apply lubrication sparingly.
Lubricate the following only when lubrication is needed:
n
Bushings: Apply a drop of light oil to a bearing if it is noisy or running dry.
n
Alignment roller clutch and paper-pick clutch: The clutches each use a
spirally wound spring riding on a metal gear core. The springs are very noisy
if they lose lubricant. Disassemble the clutch and lubricate the spring with
grease. For reassembly, the spring catch fits into the center hole of the clutch
sleeve.
Tools and supplies required
