Print quality troubleshooting
When occasional print quality problems occur, use the information in this section to help solve the
problem.
Print quality problems associated with media
Some print quality problems arise from use of inappropriate media.
●Use paper that meets HP paper specifications. See 
Supported media weights and sizes
.
● The surface of the media is too smooth. Use media that meets HP paper specifications. See
Supported media weights and sizes
.
● The print driver setting might be incorrect. Be sure that you have selected the correct driver setting
for the paper that you are using.
● The print mode might be set incorrectly, or the paper might not meet recommended specifications.
For more information, see 
Supported media weights and sizes
.
● The transparencies you are using are not designed for proper toner adhesion. Use only
transparencies designed for HP Color LaserJet printers.
● The moisture content of the paper is uneven, too high, or too low. Use paper from a different source
or from an unopened ream of paper.
● Some areas of the paper reject toner. Use paper from a different source or from an unopened ream
of paper.
● The letterhead you are using is printed on rough paper. Use a smoother, xerographic paper. If this
solves your problem, consult with the printer of your letterhead to verify that the paper used meets
the specifications for this printer. See 
Supported media weights and sizes
.
● The paper is excessively rough. Use a smoother, xerographic paper.
Overhead transparency defects
Overhead transparencies might display any of the image quality problems that any other type of media
could display, as well as defects specific to transparencies. In addition, because transparencies are
pliable while in the print path, they are subject to being marked by the media-handling components.
NOTE
Allow transparencies to cool at least 30 seconds before handling them.
●On the printer driver’s 
Paper tab, select  Transparency  as the media type. Also, make sure that
the tray is correctly configured for transparencies.
● Check that the transparencies meet the specifications for this printer. See 
Supported media weights
and sizes
.
For ordering information, see 
Part numbers .
● Handle transparencies by the edges. Skin oil on the surface of transparencies can cause spots
and smudges.
● Small, random dark areas on the trailing edge of solid fill pages might be caused by transparencies
sticking together in the output bin. Try printing the job in smaller batches.
212 Chapter 8   Problem solving ENWW
 
						

							
●The selected colors are undesirable when printed. Select different colors in the software application
or printer driver.
● If you are using a reflective overhead projector, use a standard overhead projector instead.
Print quality problems associ
ated with the environment
The printer is operating in excessively humid or dry conditions. Verify that the printing environment is
within specifications. See 
Environmental specifications.
Print quality problems associated with jams
●Make sure that all media is cleared from the paper path. See Paper jam recovery
.
● The printer recently jammed. Print two to three pages to clean the printer.
● The media does not pass through the fuser causing image defects to appear on subsequent
documents. Print two to three pages to clean the printer. However, if the problem persists see the
next section.

Calibrating the printer
The HP Color LaserJet CP4005 Series printer automatically calibrates and cleans at various times to
maintain the highest level of print quality. The user might also request the printer to calibrate via the
printer’s control panel, using QUICK CALIBRATE NOW or CALIBRATE NOW  located in the PRINT
QUALITY  menu. QUICK CALIBRATE NOW  is used for color tone calibration and takes about 65
seconds. If color density or tone seems wrong, Quick Calibration can be run. Full Calibration includes
the Quick Calibrate routines and adds Drum Phase Calibration and Color Plane Registration (CPR).
This takes about 4 minutes and 20 seconds. If color layers (black, magenta, cyan, and yellow) on the
printed page seem to be shifted from one another,  CALIBRATE NOW should be run.
The HP Color LaserJet CP4005 Series printer incorporates a new feature to skip calibration when
appropriate, thereby making the printer available more quickly. For example, if the printer is turned off
and on quickly (within 20 seconds), calibration is not needed and is skipped. In this case, the printer will
reach the  Ready state approximately 1 minute sooner.
While the printer is calibrating and cleaning, the printer will pause printing for the amount of time it takes
to complete the calibration or cleaning. For most calibrations and cleaning, the printer will not interrupt
a print job, but will wait for the job to complete before calibrating or cleaning.
