Follow the step listed below for cleaning the laser glass:

1. Turn off the power switch and open the front cover.

2. Lift the drum unit slightly and pull it out. Place the drum unit on a
drop cloth or large piece of disposable paper to avoid spilling and scattering the toner.

3.With the drum removed from the machine, clean the laser glass with a
DRY cloth. The laser glass is located on the roof inside in the machine
where the drum unit is installed. DO NOT use isopropyl alcohol or any
liquid to clean the glass

4. Remove the toner cartridge from the drum by holding down the lock
lever (purple tab) on the right side of the drum unit and lift the toner
out.
*Handle the toner cartridge carefully. If toner scatters on your hands
or clothes, immediately wipe it off and wash with cold water.

5. Gently rock the toner cartridge from side to side five or six times
to distribute the toner evenly inside the cartridge. Then, reset the
toner into the drum (be sure it clicks into place).

6. Reset drum unit in the machine.

7. Close the front cover, pressing firmly on each side until the cover
clicks into place..
