HP LaserJet M1120 Multifunction Printer - Manual (Page 103)

Problem Cause Solution
The printed page contains
wrinkles or creases. The media might be loaded incorrectly or the
input tray might be too full. Turn over the stack of paper in the input tray,
or try rotating the paper 180° in the input
tray.
Verify that the media is loaded correctly and
that the media guides are not too tight or too
loose against the stack. See
Load paper
and print media on page 35 .
The media might not meet HP specifications. Use a different paper, such as high-quality
paper that is intended for laser printers.
Air pockets inside envelopes can cause them
to wrinkle. Remove the envelope, flatten it, and try
printing again.
Toner appears around the printed
characters. The media might be loaded incorrectly. Turn over the stack of paper in the tray.
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 that is intended for laser printers.
An image that appears at the top
of the page (in solid black) repeats
farther down the page (in a gray
field). Software settings might affect image
printing. In your software program, change the tone
(darkness) of the field in which the repeated
image appears.
In your software program, rotate the whole
page 180° to print the lighter image first.
The order of images printed might affect
printing. 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
farther down the page.
A power surge might have affected the
product. If the defect occurs later in a print job, turn
the product off for 10 minutes, and then turn
on the product to restart the print job.

Print-media guidelines
● For best results, make sure that the paper is of good quality, and free of cuts, nicks, tears, spots,
loose particles, dust, wrinkles, voids, staples, and curled or bent edges.
● For best-quality printing, use a smooth type of paper. Generally, smoother media produces better
results. .
● If you are unsure what type of paper you are loading (such as bond or recycled), check the label
on the package of paper.
