Cleaning the machine
104 3. Maintenance
• 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.
• Do not touch the green surface underside of the toner
cartridge. Use the handle on the cartridge to avoid
touching this area.
3 With a dry, lint-free cloth, wipe away any dust and spilled
toner from the toner cartridge area.
While cleaning the inside of the machine, be careful not to
damage the transfer roller or any other inside parts. Do not
use solvents such as benzene or thinner. Printing quality
problems can occur and cause damage to the machine.
4 Reinsert the toner cartridge and close the front cover.
