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.
■ 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.
■ To show the printed transparency, use a standard overhead projector instead of a reflective
overhead projector.
Print-quality problems that are related to the environment
When the MFP is operating in excessively humid or dry conditions, print-quality problems can occur.
Verify that the printing environment is within specifications. See
Environmental specifications.
Print-quality problems that are related to jams
■ Make sure that all media is cleared from the paper path.
■ If the MFP recently jammed, print two or three pages to clean the MFP.
■ Repeated jams might require that you clean the MFP as described in chapter 4. It might be
necessary to process several cleaning pages through the MFP. See
Cleaning the fuser.
