							General print quality issues
The following examples depict Letter-size paper that has passed through the product short-edge first.
These examples illustrate problems that would affect all of the pages that you print, whether you print
in color or in black only. The topics that follow list the typical cause and solution for each of these
examples.
ProblemCauseSolution
Print is light or faded.The media might not meet
HP specifications.Use media that meets HP specifications.
One or more print cartridges might be
defective.Print the Supplies status page to check
the remaining life. See 
Information pageson page 68.
Replace any low print cartridges. See
Replace print cartridges on page 82.
The product is set to override the
Replace  cartridge message
and to continue printing.Replace any low print cartridges. SeeReplace print cartridges on page 82.
The print density settings may have been
changed.Set the print density setting to 0.
The product may need to be calibrated.Run a calibration. See Calibrate theproduct on page 118.
Toner specks appear.The media might not meet
HP specifications.Use media that meets HP specifications.
The paper path might need cleaning.Clean the paper path. See Clean theproduct on page 90.
One or more of the cartridges may be
leaking.Try to verify the color of the toner specks
and check the cartridge for leaks.
The cartridge waste tank may be
overfilled.Check for error code 10.98.XX in the
event log. See Event log on page 70. The
XX portion of the code identifies the
cartridge (00 is black, 01 is cyan, 02 is
magenta, 03 is yellow). If the error was
logged, replace the affected cartridge.
Dropouts appear.A single sheet of print media might be
defective.Try reprinting the job.
The moisture content of the paper is
uneven or the paper has moist spots on
its surface.Try different paper, such as high-quality
paper that is intended for color laser
printers.
The paper lot is flawed. The
manufacturing processes can cause
some areas to reject toner.Try different paper, such as high-quality
paper that is intended for color laser
printers.

							ProblemCauseSolution
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
device.If the defect occurs later in a print job,
turn the device off for 10 minutes, and
then turn on the device to restart the print
job.
  Use non-glossy media to help reduce the
severity of the defect
Solve issues with color documents
This section describes issues that can occur when you print in color.
ProblemCauseSolution
Only black is printing when the document
should be printing in color.Color mode is not selected in your
program or printer driver or the restric
color setting is on..Select color mode instead of grayscale
mode or turn off the restrict color setting.
The correct printer driver might not be
selected in the program.Select the correct printer driver.
The device might not be correctly
configured.Print a Configuration page (see
Information pages on page 68). If no
color appears on the Configuration page,
contact HP Customer Care. See 
Service
and support on page 127 or the support
flyer that came in the box.
The color supply is out and the Color
Supply Out menu setting is set to

If extremely light colors or extremely dark
colors on screen are not printing, your
software program might interpret
extremely light colors as white or
extremely dark colors as black.If possible, avoid using extremely light or
extremely dark colors.
The media might not meet
HP specifications.Use a different paper, such as high-
quality paper that is intended for color
laser printers.
The finish on the printed color page is
inconsistent.The media might be too  rough. Use a smooth paper or print media, such

							Use HP ToolboxFX to troubleshoot print-quality problems 
NOTE:Before proceeding, print a Supplies status page to see the approximate number of pages
remaining for each print cartridge. See 
Information pages on page 68.
From the HP ToolboxFX software you can print a page that helps identify whether a specific print
cartridge is causing the problem, or if the problem is with the product itself. The print-quality
troubleshooting page prints five bands of color, which are divided into four overlapping sections. By
examining each section, you can isolate the problem to a particular cartridge.
SectionPrint-cartridge
1Yellow
2Cyan
3Black
4Magenta
This page helps identify four general issues:
●Streaks in only one color: This is most likely a cartridge issue. Remove the cartridge and look
for debris on it. If no debris is found and the defect continues after the cartridge is reinstalled,
replace the cartridge.
●Streaks in all colors (in same location): Clean the printer and call for service if the problem
continues.
●Repeating defect in multiple colors:
Repeating dot in multiple colors: If the dot repeats at roughly 57 or 58 mm, run a cleaning page to
clean fuser and run several white pages of paper to clean the roller. If defect does not repeat at 57
or 58 mm, replace the cartridge of the color of the dot.
Repeating band in multiple colors: Contact HP Support.
●Single dot or Single band in one color: Print three or four additional troubleshooting pages. If
the band or dot is only in one color on most of the pages, replace the cartridge of that color. If the
band or dot moves to a different color, contact HP Support.
