Page skew
● Make sure the paper or other print media is loaded correctly and that the guides are not too
tight or too loose against the stack. See “Loading trays” on page 25.
● Check the paper type and quality. Use a different paper, such as high-quality paper intended
for laser printers. See “Print media specifications” on page 109.
● If the problem is not resolved, see “If the problem is not resolved” on page 77.
Wrinkles or creases
● Make sure that paper is loaded properly.
● Turn over the stack of paper in the input tray, or try rotating the paper 180 degrees in the
input tray.
● Open the rear output door to print to the straight-through paper path.
● Check the paper type and quality. Use a different paper, such as high-quality paper intended
for laser printers. See “Print media specifications” on page 109.
● If the problem is not resolved, see “If the problem is not resolved” on page 77.
Toner scatter outline
● Turn over the stack of paper in the tray.
● Perform a calibration. See “Calibrating the printer” on page 89.
● Small amounts of toner scatter are normal for laser printing.
● If large amounts of toner have scattered around the characters, the paper might have high
resistivity. Use a different paper, such as high-quality paper intended for laser printers. See
“Print media specifications” on page 109.
● If the problem is not resolved, see “If the problem is not resolved” on page 77.
Random image repetition
If an image that appears at the top of the page (in solid black) repeats farther down the page (in
gray field), the toner might not have been completely erased from the last job. The repeated
image might be lighter or darker than the field in which it appears.
● From your program, change the tone (darkness) of the field that the repeated image appears
in.
● From your program, rotate the whole page 180 degrees to print the lighter image first.
● Change the order in which the images are printed. For example, have the lighter image at the
top of the page, and the darker image further down the page.
● If the defect occurs later in a print job, turn the printer off for 10 minutes, and then turn the
printer on to restart the print job.
● If the problem is not resolved, see “If the problem is not resolved” on page 77.
