Overhead transparency defects

Note

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.

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 driver. 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 and/or the printed output, compare the defect against the repetitive defect ruler (page 195) to help isolate the cause to a particular component.

Check that the transparencies meet the specifications listed in the HP LaserJet Family Paper Specification 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.
