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.
