HP laserjet m1212nf - Manual (Page 235)

Problem Cause Solution
Text or graphics are skewed on
the printed page. The paper might be loaded incorrectly or the
input tray might be too full. Verify that the paper is loaded correctly
and that the paper guides are not too tight
or too loose against the stack.
The paper might not meet HP specifications. Use a different paper, such as high-quality
paper that is intended for laser printers.
The printed page contains
wrinkles or creases. The paper 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 paper is loaded correctly
and that the paper guides are not too tight
or too loose against the stack.
There might be a jam in the paper path. Clear any jams in the product.
The paper might not meet HP specifications. Use a different paper, such as high-quality

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 paper 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.
