Chapter 7: When to replace supplies
tion about printing problems that may indicate it’s time to
replace the print cartridge.
Warning!
If you are installing
the black print cartridge, make
sure you install the coating roll
when you replace the print car-
tridge.
When you need to install a new print cartridge, see
“Replacing print cartridges” on page 121 or the installa-
tion instructions that come with the new cartridge.
Coating roll
The coating roll lubricates the fuser with oil. It is located
inside the fuser under the printer’s fuser cover. You will
receive a new coating roll each time you order the black
print cartridge.
To avoid damage to the fuser, replace the coating roll each
time you replace the black print cartridge. See “Replacing
the coating roll” on page 126 for more information on how
to replace the coating roll.
With certain types of printing, you may experience print
quality problems that indicate you need to replace the
coating roll before its scheduled time. You can order a
coating roll separate from the black print cartridge. For
more information on ordering supplies, see “Ordering
supplies” on page 113.
Paper jams in the fuser, toner specks on the front of the
page or ghost images are indicators you need to replace
the coating roll before its scheduled time.
See page 113 for information about ordering a coating roll.
