Periodic cleaning of the printer is recommended.
The frequency of cleaning is dependent upon the
environment in which the printer is used. You should
clean the printer:
BAt least once a month.
BWhen the printer experiences frequent media
jams.
BWhen print quality has deteriorated.
For the detailed information, refer to “Care and
Maintenance” of the Operating Instructions installed
on your computer.
nJam at B, C, G, H:
To clear a jam, see the instructions on this
Reference Guide and “Care and Maintenance” of the
Operating Instructions installed on your computer.
nJam at A, D, E, F, MPT:
To clear a jam, refer to the label inside the front door
and “Care and Maintenance” of the Operating
Instructions installed on your computer.
n Incorrect media or wrong media settings
When “Media type mismatch”appears on the
printer panel, remove the jammed media [ see
instruction above in “Jam at A” or “Jam at MPT
(multi-purpose tray)”], then load the media in the

nReplacing Printer Components
(see page 28)
It may need to replace the following components to
solve the trouble.
Troubleshooting
For the detailed information, refer to “Care and Maintenance” of the Operating Instructions installed on your
computer.
READY indicator is blinking.
The toner is almost depleted.Read the printer panel message to
determine the printer status.
Corrective ActionTrouble
ERROR indicator is blinking.Wait for the job to be completed or
cancel the job. The printer is receiving,
processing or printing job.
Possible Cause
Exit the Menu mode by pressing
the MENU/EXIT button.
Correct the condition displayed on
the printer panel (e.g., close the
door or clear the media jam). Turn the printer off and back on
again. If the indicator is still on, the
printer requires service.  You have entered the Menu
mode in the printer panel.
The printer is not ready, is
disabled, or has detected an
error.
The printer has stopped because
it detected a user-correctable
error such as an open door or a
media jam. Error occurred that is not user-
correctable. READY indicator is off.
ERROR indicator is on.
Replace the color toner cartridge.
On the Test Print, a single color is
not uniform or many vertical
streaks (both light and dark) of
slightly different density and non-
uniform color.

							26
Corrective ActionTroublePossible Cause
Store media in the original, dust-
free package in the same
environmental conditions as the
printer. Paper doesn’t match the
environmental conditions, or it
has too much moisture.Try fresh paper, or another type of
paper. On the Test Print, halftone area
has areas of weak color.
The toner cartridge is almost
depleted and is not properly
applying toner.Replace the color toner cartridge. The toner is almost depleted.On the Test Print, a single color has
a sharp, dark or light vertical streak.
Replace the color toner cartridge soon 
The color density is set
incorrectly in the printer panel. A single color appears faded.Adjust the color density (see page 21) 
The photosensitive belt inside the
color imaging unit is scratched.Replace the color imaging unit. On the Test Print, straight, thin
light vertical line in colors.
Replace the color imaging unit.The color imaging unit is damaged.On the Test Print, a single white
spot appears in approximately the
same vertical place on the page.
Fingerprint(s) on the underside
belt or photosensitive belt
(inside) of the color imaging unit.Print several pages until the spots
fade. On the Test Print, large light
spot(s) appear randomly. 
						

							27
Corrective ActionTroublePossible Cause
Print 5-10 pages of blank pages to
clean the roller.
If you still see the problem:
BReplace the oil supply roll.
If you still see the problem:
BReplace the fuser unit. A piece of the printed image is
missing and reappears out of
place, approximately 129 mm (5²)
down the page.The fuser unit’s internal roller is
not being consistently oiled.
or
The fuser unit’s internal roller is
contaminated with toner
particles.
Replace the oil supply roll.
The oil supply roll has reached
the end of its useful life. Media frequently wraps around
the fuser unit.
Reinsert the color imaging unit to
correct the contact for the charge
unit. The entire page prints in black,
including the borders.Bad electrical contact for the
Charge unit.
The charge unit is broken.
The cleaning pad may get dirty
with toner.Replace the cleaning pad. The back of the printed page
appears dirty.
Remove and reinsert the charge
unit.
Replace the charge unit.
Solid color print for green, red and
blue are not printed out evenly in
the Adjustment to Media test
pattern.Unrecommended media is used.
Adjust the Adjustment to Media
value using the Printer panel. (See
“Adjusting the Adjustment to Media
Setting” in the “Settings and
Printing” installed on your
computer).

Use the recommended media
(see page 18).

*1Average life is based on an average of 5%
coverage of the printable area and standard
density for any one color (refer to Example A:
Monochrome 5% coverage). For the components
below, the average life may decrease depending
on the percentage of colors and coverage used.

2If you print with high density when “Low 
Toner” is displayed, you may get  faded printout
before “ Toner Empty” is displayed.

3Specialty media (Transparencies, coated paper,
etc.) will result in shortening the life of each
consumable. When one page is printed on this
type of media, 2 pages are counted.
Do not insert the used oil supply roll into the new
fuser unit; it may damage the new fuser unit.
*
4Using media except the recommended media
(see page 18) will result in shortening the life of
consumable.

5When you have just replaced the transfer unit or
cleaning pad, you must reset the counter to 100%
remaining (see the each supplys manual).

nMedia sizes/Margins and print
area
Refer to “Specifications” of the Operating
Instructions installed on your computer.
nTypes of Paper to avoid
BExtremely smooth or shiny paper or paper that is
highly textured
BLetterhead imprinted with low temperature or
thermography. These materials may transfer onto
the fusing roller and cause damage. Any pre-
printed paper should use inks compatible with
200°C (392°F) for 0.1 second.
BDamaged or wrinkled paper, or paper with
irregularities such as tabs, staples, etc.
BMultipart forms or carbonless paper
BPaper with a 25% or more cotton and/or fiber
content
BInk jet media(paper, transparency,etc.) 
(It may transfer onto the fuser unit roller and cause
damage.)
nDuplex printing
Manual duplex printing is possible by using the multi-
purpose tray. Automatic duplex printing is possible
by installing the optional 2nd cassette feeder with
ADU. However, you should not expect the same
print quality and reliability that you get with single-
sided printing. We strongly recommend that you
follow the guidelines below.
Notes for manual duplex printing:
BDo not load more than 50 sheets in the multi-
purpose tray.
BBefore loading paper in the multi-purpose tray,
adjust it so that the edges of the media are lightly
touching the media guides of the multi-purpose
tray.
BUse multi-purpose tray for second side printing.
Specifications
For detailed information on specifications, refer to
“Specifications” of the Operating Instructions
installed on your computer.Notes for manual / automatic duplex printing:
BIt is strongly suggested to use color laser bond
paper.
BBefore printing on the first side, set the unprintable
area [at least 15 mm (0.59²) in length] on the top
of paper (see below.)
BWhen printing on the first side, avoid printing
photograph or graphic in solid color to prevent
paper jamming. It may cause a damage to the
printer.
