Print Quality Problems
This section describes likely causes of and possible solutions for problems with
print quality.
Checking the Condition of the Machine
If there is a problem with the quality of printing, first check the condition of the
machine.
Possible Cause Solution
There is a problem with the ma-
chine's location.
Make sure that the machine is on a level surface. Place the
machine where it will not be subject to vibration or shock.
Unsupported types of paper is
used.
Make sure that the paper being used is supported by the ma-
chine. See p.64 “Supported Paper for Each Tray”.
The paper type setting is incor-
rect.
Make sure that the paper type setting of the printer driver
matches the type of paper loaded. See p.88 “Specifying Pa-
per Type and Paper Size”.
A non-genuine print cartridge is
being used.
Refilled or non-genuine print cartridges reduce print quality
and can cause malfunctions. Use genuine print cartridges
only. See p.328 “Consumables”.
An old print cartridge is being
used.
Print cartridges should be opened before their expiration
date and used within six months of being opened.
The machine is dirty. See p.311 “Cleaning”, and clean the machine as required.
Color degradation has occurred. Color degradation may occur in color printing after the ma-
chine is moved or a large number of pages are printed. In
this case, adjust color registration by executing [Color Regist.]
in [Machine Settings].
