When you open the front cover and work inside the machine, it is
highly recommend that you remove the paper transfer belt first.
Because the work you do could contaminate the paper transfer
belt.
4. Hold
ing both handles on the toner cartridge, thoroughly rock it from side
to side to redistribute the toner.
If toner gets on your clothing, wipe it off with a dry cloth and wash
clothing in cold water. Hot water sets toner into fabric.
5. Slide the toner cartridge back into the machine.
6. Hold

the inside of the front cover.
7. Lower the paper transfer belt until it is parallel with the front cover and
firmly seated.
8. Close the front cover. Ensure that the cover is securely closed.
If the front cover is not completely closed, the machine will not

TIPS FOR AVOIDING PAPER JAMS
By selecting the correct media types, most paper jams can be avoided.
When a paper jam occurs, refer to the below guidelines.
• Ensure that the adjustable guides are positioned correctly (See "Loading
paper in the tray" on page 37).
• Do
not overload the tray. Ensure that the paper level is below the paper
capacity mark on the inside of the tray.
• D
o not remove paper from the tray while your machine is printing.
• F
lex, fan, and straighten paper before loading.
• D
o not use creased, damp, or highly curled paper.
• D
o not mix paper types in a tray.
• U
se only recommended print media (See "Setting the paper Type and
Size" on page 41).
• Ensure that the recommended side of the print media is facing up in the
tray, or facing down in the multi-purpose tray.
• If
paper jams occur frequently when you print on A5/B5-sized paper:
Load the paper into the tray with the long edge facing the front of the
tray.
If load the paper this way, printing both sides of the paper (duplex) is not
supported.
In the Printing
Preferences window, set the page orientation to be
rotated 180 degrees (See "Opening printing preferences" on page 44).

In the multi-purpose tray
Click this link to open an animation about clearing a jam.
When you print using the multi-purpose tray and the machine detects
that there is either no paper or that the paper has been improperly
loaded, follow the next steps to release the jammed paper.
1. If th
e paper is not feeding properly, pull the paper out of the machine.
If you do not see the jammed paper or if there is any resistance when
you pull, stop and go to step 3.
2. Open and close the front cover to resume printing.
If the front cover is not completely closed, the machine will not

3. Using the handle, completely open the front cover.
4. R
emove the jammed paper by pulling in the direction shown. To avoid
tearing the paper, pull it out gently and slowly.
• Do not touch the green surface, the OPC drum or the front of
the toner cartridge, with your hands or any other material. Use
the handle on each cartridge in order to avoid touching this
area.
• Be careful not to scratch the surface
of the paper transfer belt.
• If you leave the front cover open for more than a few minutes,
th
e OPC drum can be exposed to light. This will cause damage
to the OPC drum. Close the front cover when the installation
needs to be halted for any reason.

Vertical repetitive
de
fects
If marks repeatedly appear on the printed side of
the page at even intervals:
• T
he toner cartridge may be damaged. If you
still have the same problem, remove the
toner cartridge and, install a new one (See
"Replacing the toner cartridge" on page 82).
• Pa
rts of the machine may have toner on
them. If the defects occur on the back of the
page, the problem will likely correct itself
after a few more pages.

Background
sca
tter
A
Background scatter results from bits of toner
randomly distributed on the printed page.
• T
he paper may be too damp. Try printing
with a different batch of paper. Do not open
packages of paper until necessary so that
the paper does not absorb too much
moisture.
• If ba
ckground scatter occurs on an envelope,
change the printing layout to avoid printing
over areas that have overlapping seams on
the reverse side. Printing on seams can
cause problems.
• If b
ackground scatter covers the entire
surface area of a printed page, adjust the
print resolution through your software
application or in Printing Preferences (See
"Opening printing preferences" on page 44).
Misformed
ch
aracters
If characters are improperly formed and
producing hollow images, the paper stock may
be too slick. Try different paper (See "Print
media specifications" on page 89
).
