5.4 Service Cleaning Procedure
Proper diagnosis of printer problems requires that the printer be cleaned before troubleshooting begins.
This section directs you in performing the cleaning and preliminary checkout procedures.
5.4.1 Preparation Procedure
1 Switch off the printer power.
2 Disconnect the power cord from the AC outlet.
3 Open the Front Cover.
4 Remove the EP Cartridge and store it in a safe, dark place.
5 During the cleaning procedure, check for foreign objects, such as staples, paper clips, etc., in the
printer. Also check for other problems, such as damaged or crimped wires, loose connectors or
terminals, and worn or damaged parts.
5.4.2 Paper Path Cleaning Procedure
1 Remove the Transport Chute Assembly. Use a brush to clean the Detack Saw.
2 Check the paper path and the rollers along the path for the presence of foreign object. Remove
any objects found, then use a brush or dry cloth to clean the paper path and the rollers.
NOTE: Do not use the brush on the BTR surface. If the surface is heavily contaminated, use a vacuum
cleaner to clean the surface.
NOTE: For heavy contamination, use a damp cloth (water or cleaning solvent) to clean the rollers. Dry
them with a clean cloth.
3 Remove the Top Cover. Use a brush to clean the Fan and the Top Cover portion around the Fan
Exhaust.
NOTE: Suffocated exhaust area may cause an overheat of the printer interior.
4 Run a few test prints again to check for proper printer operation and print quality.
