HP LaserJet Printers - Print Media Guide

Using overhead transparencies
Understanding the types and quality of overhead transparencies and following the HP recommendations will
help to ensure proper operation of your HP LaserJet printer.

Guidelines for using overhead transparencies
NOTE: Digital multimedia projectors are now the preferred technology for projecting images, resulting in a
decline in use of overhead transparency (OHT) projectors. HP no longer produces overhead transparencies and
does not perform extensive testing of overhead transparencies for its products. HP will verify that overhead
transparencies designed for laser printers will not damage your HP LaserJet printer and will meet minimum
performance requirements.
Overhead transparency lm must be designed specically for use with laser printers. Photocopy transparency
lm might not be compatible with laser printers because of higher temperature and stiness requirements.
Color laser printers also require dierent lm from that used in monochrome printers to ensure proper color
reproduction and meet fusing requirements.
Overhead transparency lm is very smooth and must have a topcoat to provide the proper electrical and toner
adhesion properties. A transparency that is made of incompatible material or that is too thin can easily melt in or
wrap around the fuser and damage your printer. The thickness requirement for monochrome overhead
transparency lm is 0.10 mm to 0.11 mm (4.0 mils to 4.4 mils). For color overhead transparency lm, the
thickness requirement is 0.12 mm to 0.13 mm (4.8 mils to 5.2 mils).
Overhead transparency materials must be able to withstand the heat and pressure of the fusing process.
Materials must not discolor, oset, or release undesirable emissions when heated to 205°C (401°F) for 0.1
second (0.4 second for HP color LaserJet printers). See your HP LaserJet printer user guide for detailed
instructions on using overhead transparencies.
CAUTION: Not all HP LaserJet printers support overhead transparencies. To determine if overhead
transparencies are supported for your product, see the product user guide.
Guidelines for using overhead transparencies
Follow these guidelines for using overhead transparencies to ensure optimal performance.
The following table summarizes the overhead transparency properties and specications.
CAUTION: To prevent jamming or poor-quality output, HP recommends using monochrome transparencies
with HP LaserJet monochrome printers and color transparencies with HP color LaserJet printers.
NOTE: The specications listed in this section generally apply to all HP LaserJet printers. See the support
documentation that came with your printer for product-specic information.
