7.1.7 Cleaning the Optical Unit
Dust may accumulate on the optical unit glass, causing document scanning prob-
lems: it is thus advisable to clean the glass periodically.
1) Unplug the power cord from the mains socket and flip open the printer cover.
2) Move the print head against the left side, then lift the optical unit screen acting on
the right side lever (fig. 7-5).

3) Keeping the screen raised, clean the optical unit glass using a cloth dampened
with a specific glass cleaning product, then carefully wipe dry (fig. 7-6).
