Periodic cleaning

Your fax requires little periodic maintenance. Please note the following before cleaning:
• Be sure to disconnect the power cord before cleaning the fax. Since documents in memory are erased when the
power is disconnected, print any documents stored in memory before disconnecting the power cord (see p. 33).
• Do not use tissue paper, paper towels, or similar materials for cleaning; they can stick to the components or
generate static charges.
Never use volatile liquids such as thinners, benzene, acetone, or any other chemical cleaner to clean the interior of the
fax.

Cleaning the exterior of the fax

1 Disconnect the power cord from the fax.
2 Wipe the exterior of the fax with a clean, soft, lint-free cloth moistened with water or diluted
dishwashing detergent solution.
3 When you are finished, reconnect the power cord.

Cleaning the interior of the fax

Cleaning inside the printer cover
To prevent ink spots and paper dust from accumulating inside the fax and affecting print quality, clean the print area
of the fax periodically.
1 Disconnect the power cord from the fax, then open the printer cover.
Do not touch the components or any metal parts.
2 Use a clean, soft, dry, lint-free cloth to remove any
ink or paper debris from the interior of the fax
(shaded area), especially around the four pinch
rollers.
• Dirt and dust particles that collect on the underside of the printer cover
affect the quality of the documents you copy or send.
• Be careful not to touch the BJ cartridge or its holder.
3 When you are finished, close the printer cover and
reconnect the power cord.
Be sure to close the printer cover until it locks into place.
