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.
The machine
does not print
special-sized
paper, such as
billing paper.
Paper size and paper size
setting do not match.
Set the correct paper size in the Custom in
Paper tab in Printing Preferences (see
"Opening printing preferences" on page 76).
The printed
billing paper is
curled.
The paper type setting
does not match.
Change the printer option and try again. Go to
Printing Preferences, click Paper tab, and set
type to Heavy 90-120g (see "Opening printing
preferences" on page 76).
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 143).
• 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 149).
• The surface of the LSU part inside the machine may be dirty. Clean the
inside of your machine (see "Cleaning the machine" on page 149). If
these steps do not correct the problem, contact a service
representative.
The top half of the
paper is printed
lighter than the
rest of the paper
The toner might not adhere properly to this type of paper.
• Change the printer option and try again. Go to Printing Preferences,
click the Paper tab, and set the paper type to Recycled (see "Opening
printing preferences" on page 76).
