If the original is not copied clearly, clean the machine. For high-quality printouts, we recommend cleaning the machine once or twice a month.
Exterior
Clean the exterior of the machine.
1) Turn OFF the main power switch and disconnect the power cord.
2) Wipe the machine’s exterior with a clean, soft, lint-free cloth dampened with water or diluted dishwashing detergent solution.
3) Wait for the machine to dry, then reconnect the power cord and turn ON the main power switch.
Interior
Clean the machine’s print area periodically to prevent toner powder and paper dust from accumulating inside.
Cleaning the Fixing Unit
If black streaks appear on printed output, the fixing unit may be dirty. Also, you should use the Fixing Unit Cleaning procedure every time the toner cartridge is
replaced. Print the cleaning pattern on LTR paper for cleaning the fixing unit.

Printing starts.
- Do not use alcohol, benzene, paint thinner, or other solvents for cleaning. Doing so may result in damage to the plastic parts.
- Do not use tissue paper, paper towels, or similar materials for cleaning; they can stick to the components or generate static charges.
- Disconnect the power cord from the power outlet regularly, and clean the area around the base of the power plug’s metal pins and the power outlet with a dry cloth
to ensure that all dust and grime is removed. If the power cord is connected for a long period of time in a damp, dusty, or smoky location, dust can build up around
the power plug and become damp. This may cause a short circuit and result in a fire.
MEMO:
-
You cannot send or receive documents when the main power switch is turned off or the power cord is disconnected.
- If the main power switch is turned ON, all jobs waiting in the print queue will be erased.
- Documents received into memory and documents stored for delayed send will be retained for approximately 60 minutes after the power cord has been disconnected.
MEMO:
- As cleaning paper, LTR or A4 paper must be loaded in the paper drawer or the stack bypass tray.
- Cleaning the fixing unit takes approximately 60 seconds.
