• If the groove of the drum cartridge is dirty, lines 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.
• 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.
• Insert the cleaner (1) into the left groove (2) 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 (3).
Note:
• Be sure to clean all the way to the edge of each groove.
