clean flat surface.
3 With a dry lint-free cloth, wipe away any dust and spilled toner from

Caution
• To prevent damage to the toner cartridge, do not expose it to
light for more than a few minutes. Cover it with a piece of
paper, if necessary.

cartridge. Use the handle on the cartridge to avoid touching
this area.

the transfer roller, located underneath the toner cartridge. Oil
from your fingers can cause print quality problems.
