Cleaning the drum cartridge
Important:

or dirty patterns may appear on printed sheets.
Be sure to remove any toner remaining on the
inside of the drum cartridge to maintain the print
quality.
L A cleaner for the drum cartridge is supplied with the
replacement toner cartridge. If you replace only the
toner cartridge, clean the drum cartridge using the
cleaner.
L Insert the cleaner (n) into the left groove (o) and
move it from side to side at least 3 times to clean the
inside of the drum cartridge. Repeat this for the right
groove (p).
