USER MAINTENANCE
Cleaning the document glass and the automatic document feeder
If the document glass, document cover or automatic document scanning unit have dirty spots, these spots will form
lines in scanned images. These will show up as defects when the images are printed. Always keep these parts clean.
\
Wipe with a clean, soft cloth. If necessary, moisten the
cloth with water or a small amount of neutral detergent.
When finished, wipe dry with a clean cloth. When
cleaning, do not use thinner, benzene, or similar
volatile cleaning agents.
If black or white stripes appear on printed images of originals that were fed through the
automatic document feeder, wipe the long narrow glasses in the scanning unit ((A) and
(B) in the illustration).
Cleaning the main charger of the photoconductive drum
If black (or white) lines appear even after you have cleaned the document glass and document feeder, use the
charger cleaner to clean the main charger that charges the drum.
