Printhead Window Cleaning Procedure
Do not use cleaning fluids on the printhead window. Do not use a
bare cotton swab. The swab deposits lint on the window.
Note: The printhead window is a coated glass. Do not push too
hard and scratch or break the glass.
1. Remove the print cartridge.
2. Fold a lint free cloth over a cotton swab.
3. Open the shutter.
4. Insert the swab and cloth combination in the printhead window
slot, then slide it left to right several times. Move the swab to a
clean spot on the cloth and repeat the cleaning procedure. Do
this procedure several times to make sure the window is clean.
Cleaning The Transfer Roller
Power off the printer. Power on and let it complete POST. Do this two
to three times.
