Printing quality problems
If the inside of the machine is dirty or paper has been loaded improperly, there might be a reduction in print quality. See the table below to clear the problem.
Condition
Suggested solutions
Light or faded print
•
If a vertical white streak or faded area appears on the page, the toner supply is low. Install a new toner cartridge (see "Replacing the
toner cartridge" on page 87).
•
If a vertical white streak or faded area still appears on the page even though the machine has enough toner supply, open and close
the front door 3 ~ 4 times (see "Machine overview" on page 20).
•
The paper may not meet paper specifications; for example, the paper may be too moist or rough.
•
If the entire page is light, the print resolution setting is too low or the toner save mode is on. Adjust the print resolution and turn
the toner save mode off. See the help screen of the printer driver.
•
A combination of faded or smeared defects may indicate that the toner cartridge needs cleaning. Clean the inside of your machine
(see "Cleaning the machine" on page 95).
•
The surface of the LSU part inside the machine may be dirty. Clean the inside of your machine (see "Cleaning the machine" on page
95). If these steps do not correct the problem, contact a service representative.
