850 Printers
The printer should be cleaned when prints have oily streaks, stray ink or smeared ink. Cleaning may
also be needed when paper is not picking reliably from the paper tray, or the pick and feed rollers are
visibly dirty. How often you need to clean the printer depends on how heavily the printer is used and
the environment in which it is used. Less frequent cleaning is required when high quality, laser bond
paper is used for printing.
Use the following procedures if the printer’s automated paper path cleaning procedure — located in
the Troubleshooting menu, "Remove Ink Smears," — fails to resolve the problem.
Cleaning supplies
The cleaning kit contains presoaked alcohol wipes that are recommended for cleaning the printer.
If you purchase isopropyl alcohol, always use alcohol that is at least 90% pure; alcohol that has
additives can damage the printer.
Warning
Alcohol is flammable; keep alcohol-soaked wipes away from hot surfaces.
Cleaning for oily streaks
1.
Open the front cover.
2.
Remove the maintenance drawer (A) from the printer.
3.
Use a lint-free wipe to gently wipe any excess debris from the clear plastic wiper blade.
4.
Reinsert the maintenance drawer into the printer.

Cleaning for ink smears or jams: paper-feed rollers
Clean the paper-feed rollers if media feeds improperly, or if prints have ink smears.
Caution
Hot surfaces exist behind the middle paper-feed rollers. To avoid personal injury during
cleaning procedures, do not reach in behind these rollers.
1.
Open the front cover.
2.
Remove the maintenance drawer (A) from the printer.
3.
The upper paper-feed rollers are located above the slot for the maintenance drawer (A). To clean
these rollers:
a.
Place a prepackaged alcohol-soaked wipe against each upper rubber roller, pressing to create
pressure against the roller.
b.
Use the thumbwheel to turn the upper rollers. The upper rubber rollers should rotate
four or
five complete revolutions
for each roller segment to ensure proper cleaning. Scrub each roller
thoroughly.
If the wipe becomes dirty, discard it and use another.
4.
To clean the middle rubber feed roller behind the metal plate:
a.
Place a prepackaged alcohol-soaked wipe against the underside of each middle roller.
b.
Using your hand, rotate the middle roller.

black rubber; the other set is white plastic. To clean the lower rollers:
a.
Place and hold a prepackaged alcohol-soaked wipe on top of the white and black rollers.
b.
Move the thumbwheel to turn the rollers. Rotate the rollers
four or five complete revolutions
for each roller segment to ensure proper cleaning.

Cleaning for ink smears or jams: paper-exit path
Clean the paper-exit path if media feeds improperly, or if prints have ink smears.
Caution
To avoid damaging the print drum and rapid release guide, never use any sharp objects in
this area, or scrape excess ink with a tool or fingernail.
1.
Open the exit cover.
2.
To clean the rubber exit rollers:
a.
Wrap an alcohol-soaked wipe around the index finger of one hand.
b.
Press your wipe-covered finger against each roller.
c.
Move the thumbwheel to turn the rollers. Rotate the rollers
four or five complete revolutions
for each roller segment to ensure proper cleaning.
3.
To clean the two sets of ribbed exit guides under the exit cover, gently wipe the raised ribs using
an alcohol-soaked wipe.
Note
You may notice some staining of the exit rollers while performing
the cleaning procedure; this is normal and does not indicate
additional cleaning is necessary. Simply clean rollers to remove
any build-up of ink.
