Chapter 6: Replacing supplies
Photoconductors
The photoconductor is the cylindrical drum that inserts in
the toner cartridge. Just as there is a cyan, magenta, yel-
low, and black toner cartridge, there is also a unique cyan,
magenta, yellow, and black photoconductor. Together,
the photoconductor and the toner cartridge create the
print unit.
You can purchase the black photoconductor separately.
However, the three color photoconductors come packaged
together. You should always replace all three color photo-
conductors at the same time.
The average yield of each photoconductor is 13,000 pages.
The actual yield depends on the size paper you use and
the Printer Usage setting you select from the Setup Menu.
If you select Maximum Speed—the printer default—the
printer alerts you to replace all four photoconductors at
the same time. If you select Maximum Yield, you will
probably replace the black photoconductor before you
need to replace the three color photoconductors. See
“Printing color and mono jobs” on page 63 for more infor-
mation about the Printer Usage settings.
After the printer determines that the photoconductors
have printed 12,900 pages, the printer displays
84 Color PC
Life Warning
or
84 Black PC Life Warning
. If you do not
already have replacement photoconductors available,
order them at this time.
Press
Go
to clear the attendance message. The
Supplies
sta-
tus message then appears on the second line of the display
to remind you there are supplies that need attention. Open
the Supplies Menu to view the status of the four photo-
conductors.
After posting the
PC Life Warning
messages, the printer
counts 100 pages and then displays
84 Color PC Drums
Exhausted
or
84 Black PC Drum Exhausted
. If the print qual-
ity is still acceptable, you can press
Go
and resume print-
ing. However, the printer continues to display the
PC Drum
Exhausted
message each time you turn the printer on and
each time you open and close the top cover until you
replace the photoconductors.
You’ll want to replace the photoconductors when you
notice print quality problems, such as light printing, spots
on the page, or voids in printed characters. See page 109
