DRUM CARTRIDGE REPLACEMENT

The useful life of the drum cartridge is approximately 18,000 copies. When the
internal counter reaches approximately 17,000 copies, the error indicator will light up
and "A DRUM CARTRIDGE WILL BE NEEDED SOON" will appear in the display.
For more information on purchasing a drum cartridge, see START GUIDE. When the
error indicator blinks and "REPLACE THE DRUM CARTRIDGE" appears in the
display, the machine will stop operating until the cartridge is replaced. Replace the
drum cartridge at this time.
1Remove the TD cartridge (see "TD (TONER/DEVELOPER)
CARTRIDGE REPLACEMENT" (p.157)).
When closing the covers, be sure to close the front cover securely and
then close the side cover. If the covers are closed in the wrong order,
the covers may be damaged.
Do not remove the protective cover on the drum portion (black paper) of
a new drum cartridge before use. The cover protects the drum against
external light.
