							Solving general printing problems
In addition to the issues and solutions that are listed in this section, see Troubleshooting
common Macintosh problems if you are using a Macintosh computer, and see
Troubleshooting common PostScript problems if you are using the PS driver.
Printer selects media from the wrong tray.
Cause
Solution
The tray selection in the software program might
be incorrect.For many software programs, the paper tray
selection is found on the  Page Setup menu
within the program.
Remove any media in other trays to make the
printer select from the correct tray.
For Macintosh computers, use the HP LaserJet
Utility to change the priority of the tray.
The configured size does not match the size of
the media that is loaded in the tray.Through the control panel, change the
configured size to match the size of the media
that is loaded in the tray.
Printer does not pull paper from tray.
Cause
Solution
The tray is empty.Load paper in the tray.
The paper guides are set incorrectly.To set the guides correctly, see Loading trays .
For the 500-sheet paper tray, make sure that the
leading edge of the paper stack is even. An
uneven edge can prevent the lift plate from rising.
Paper curls when it exits the printer.
Cause
Solution
The paper curls when it exits to the top output bin.Open the rear output bin to allow the paper to
exit in a straight path through the printer.
Turn over the paper that you are printing on.
Reduce the fusing temperature to reduce the
curling. (See 
Selecting the correct fuser mode .)
First sheet of media jams in the print-cartridge area.
Cause
Solution
A combination of high humidity and high
temperature is affecting the media.Adjust the printer for high humidity and high
temperature conditions.

							Print job is extremely slow.Cause
Solution
The job might be very complex.
The maximum speed of the printer cannot be
exceeded even when more memory is added.
Printing speeds might be automatically reduced
when printing on custom-sized media.
Note: Slower speeds are expected when printing
on narrow paper, when printing from tray 1, or
when using the HIGH 2 fuser mode.Reduce the complexity of the page or try
adjusting the print-quality settings. If this problem
occurs frequently, add memory to the printer.
You are printing a PDF or PostScript (PS) file but
are using a PCL printer driver.Try using the PS printer driver rather than the
PCL printer driver. (You can usually do this from
a software program.)
In the printer driver,  Optimize for: is set to
cardstock, heavy, rough, or bond paper.In the printer driver, set the type to plain paper
(see 
Printing by type and size of media (locking
trays) ).
Note : If you change the setting to plain paper,
the print job will print faster. However, if you are
using heavy media, for best results leave the
printer driver set to heavy even though printing
might be slower.
Print job prints on both sides of the paper. 
Cause
Solution
The printer is set for duplexing.See Changing the settings for a print job  to
change the setting, or see the online Help.
Print job contains only one page but the printer  processes the back side of the page as well
(the page comes part of the way out,  and then goes back into the printer).
Cause
Solution
The printer is set for duplexing. Even if the print
job contains only one page, the printer also
processes the back side.See Changing the settings for a print job  to
change the setting, or see the online Help.
Do not try to pull the page out of the printer
before duplexing is complete. Jamming might
result.
Pages print, but are totally blank.
Cause
Solution
The sealing tape might still be in the print
cartridge.Remove the print cartridge and pull out the
sealing tape. Reinstall the print cartridge.
The file might have blank pages.Check the file to make sure that it does not
contain blank pages.

							The printer prints, but the text is wrong, garbled, or incomplete.Cause
Solution
The printer cable is loose or defective.Disconnect the printer cable and reconnect it.
Try a print job that you know works. If possible,
attach the cable and printer to another computer
and try a print job that you know works. Finally,
try a new cable.
The printer is on a network or sharing device and
is not receiving a clear signal.Disconnect the printer from the network and use
a parallel or USB cable to attach it directly to a

							Guidelines for using paper
For best results, make sure the paper is of good quality, and free of cuts, nicks, tears, spots,
loose particles, dust, wrinkles, voids, and curled or bent edges.
If you are unsure what type of paper you are loading (such as bond or recycled), check the
label on the package of paper.
For a complete list of supported media, see 
Supported types and sizes of print media.
The following problems with paper cause print quality deviations, jamming, or even damage
to the printer.
SymptomProblem with paperSolution
Poor print quality or toner
adhesionThe paper is too moist, too
rough, too heavy, too smooth,
or it is embossed or from a
faulty paper lot.Try another kind of paper,
between 100 and 250
Sheffield, and with 4 to 6%
moisture content.
Dropouts, jamming, curlThe paper has been stored
improperly.
The paper varies from side to
side.Store paper flat in its moisture-
proof wrapping.
Turn the paper over.
Excessive curlThe paper is too moist, has the
wrong grain direction, or is of
short-grain construction.
The paper varies from side to
side.Open the rear output bin, or
use long-grain paper.
Turn the paper over.
Jamming, damage to printerThe paper has cutouts or
perforations.Use paper that is free of
cutouts or perforations.
Problems with feedingThe paper has ragged edges,
or it is from a faulty paper lot.
The paper varies from side to
side.
The paper is too moist, too
rough, too heavy, or too smooth.
It has the wrong grain direction,
is of short-grain construction, or
it is embossed.Use high-quality paper that is
made for laser printers.
Turn the paper over.
Try another kind of paper,
between 100 and 250
Sheffield, and with 4 to 6%
moisture content.
Open the rear output bin, or
use long-grain paper.
NOTEDo not use letterhead paper that is printed with low-temperature inks, such as those used in
some types of thermography. Do not use raised or embossed letterhead. The printer uses
heat and pressure to fuse toner to the paper. Make sure that any colored paper or preprinted
forms use inks that are compatible with this fusing temperature (200°C or 392°F for
0.1 second).
CAUTION
Failure to follow these guidelines could cause jams or damage to the printer.
