Overhead transparency defects
Overhead transparencies may display any of the image quality defects
shown in the previous samples. 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.
• Make sure that “transparency” is checked as the media type in the
Paper Tab in the printer drive. Also, make sure that the media input
tray is correctly configured for transparencies. When Transparency
is selected as the media type and ColorSmart II is selected on the
Color tab, the printer will use a color treatment optimized for
projection.
• If transparencies show lines and creases in the media or in the
printed output, compare the defect against the repetitive defect ruler
(see the service manual) to help isolate the cause to a particular
component.
• Check that the transparencies meet the specifications listed in the
HP LaserJet Family Print Media Guide.
• If the transparencies have spots or smudges, reprint them being
careful not to touch the surface of the media. Skin oils can
contaminate transparencies, causing spots and smudges.
• Small random dark areas on the trailing edge of solid fill pages may
be caused by transparencies sticking together in the face up bin. Try
printing the job in smaller batches.
• Send transparencies only to the face-down output bin.
Transparencies created on the printer may look rough, but they can still
be used successfully on reflective-type (portable) transparency
projectors.
