and avoids damage when the cover is removed. (Not shown).
· Detach the platen knob (1).
· Insert a flat-blade screwdriver through the slots (2) and disengage the claws of the cover. The Microline
390 and Microline 390-Plus have three slots. The Microline 391 and Microline 391-Plus have five slots.
· Lift the front of the upper cover assembly (3) and remove the assembly.
· The upper cover assembly contains the access cover assembly (4), the sheet separator assembly (5),
the rear cover (6), and the middle cover (7)
CAUTION:
Do NOT rotate the access cover past the vertical when removing it. The tab extensions can break.
Before installing the cover, move the bail arm lever towards the back of the printer and move the release
lever towards the front of the printer.
After installation, verify that the cover is correctly seated in the front slots. The cover will warp if it is
incorrectly installed. Check that the paper bail moves properly.
When cleaning, refer to Section 3.4 of this Service Handbook
