CHANGING THE IMAGE DRUM
When the image drum reaches the end of its product life, *** CHANGE
DRUM
is displayed in the control panel (*** is the color name). If
printing continues without replacing the image drum,
CHANGE ***
IMAGE DRUM
is displayed and printing is cancelled.
Change the toner cartridge and clean the LED head at the same time
as changing the image drum.
Image drum life is approximately 23,000 sheets of letter-size media.
This assumes a typical office environment where 20% of print jobs
are one page emails, 30% are 3-page documents containing only
words (no graphics) and 50% are print runs of 15 pages or more.
1. Switch off the printer and open the top cover.
CAUTION!
• Never expose the image drum to light for more than 5
minutes.
• Never expose the image drum to direct sunlight.
• Never touch the surface of the green drum inside the
image drum unit.
