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 130).
• 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 18).
• 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 134).
• The surface of the LSU part inside the machine may be dirty. Clean the
inside of your machine (see "Cleaning the machine" on page 134). If
these steps do not correct the problem, contact a service representative.
