Solution
1. Open the top cover.
a. Clean the four LED bars (a) using
the cleaning pad supplied with
each new toner cartridge.
b. Check the Imaging Unit and re-
move any foreign material if found.
Caution: Do not leave the top cover open for more than 10 minutes
without covering the Imaging Unit as damage could result. Use the
dark bag that came with the Imaging Unit or dark paper as a cover.
2. If the problem persists after cleaning the LED bars,
do the following:
a. Check the toner for the problem color. Replace the
toner if low.
b. Lift out the Imaging Unit, for the problem color, keeping
the toner cartridge installed.
c. With the Imaging Unit in an upright
position (to avoid toner spills), lift it
high enough to visually inspect the
shiny green surface underneath.
d. If the shiny green surface has scratches or damage that
align with the defect of the print, replace the Imaging Unit.
Note: Some slight scratching is normal.
Caution: Do not touch the shiny green surface of the Imaging Unit.
Set the Imaging Unit on a hard flat surface only as scratching or
damage can occur causing more print-quality problems.
