Solve print-quality problems
Print-quality problems associated with media
Some print-quality problems arise from the use of inappropriate media.
●
Use media that meets HP specifications.
●
The surface of the media is too smooth. Use media that meets HP specifications.
●
The moisture content is uneven, too high, or too low. Use media from a different source or from
an unopened ream.
●
Some areas of the media reject toner. Use media from a different source or from an unopened
ream.
●
The letterhead you are using is printed on rough media. Use a smoother, xerographic media. If
this solves your problem, ask the supplier of your letterhead to use media that meets the
specifications for this device.
●
The media is excessively rough. Use a smoother, xerographic media.
●
The driver setting is incorrect.
●
The media that you are using is too heavy for the media type setting that you selected, and the
toner is not fusing to the media.
Print-quality problems associated with the environment
If the device is operating in excessively humid or dry conditions, verify that the printing environment
is within specifications.
Print-quality problems associated with jams
Make sure that all sheets are cleared from the paper path.
● If the device recently jammed, print two to three pages to clean the device.
●
If the sheets do not pass through the fuser and cause image defects on subsequent documents,
print three pages to clean the device. If the problem persists, print and process a cleaning page.
Overhead transparency defects
Overhead transparencies can contain any of the image-quality problems that appear in other types of
media in addition to defects that are specific to transparencies. In addition, because transparencies
are pliable, they can be affected by the media-handling components in the paper path.
NOTE Allow transparencies to cool at least 30 seconds before handling them.
●
On the printer driver Paper tab, select Transparency as the media type. Also, make sure that
the tray is correctly configured for transparencies.
●
Make sure that the transparencies meet the specifications for this monochrome HP LaserJet
MFP. For more information, consult the HP LaserJet Printer Family Print Media Guide.
