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 film must be designed specifically for use with laser printers. Photocopy transparency film might not be compatible with laser printers because of higher temperature and stiffness requirements. Color laser printers also require different film from that used in monochrome printers to ensure proper color reproduction and meet fusing requirements. Overhead transparency film 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 film is 0.10 mm to 0.11 mm (4.0 mils to 4.4 mils). For color overhead transparency film, 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, offset, 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 specifications. 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 specifications listed in this section generally apply to all HP LaserJet printers. See the support documentation that came with your printer for product-specific information. Table 2-4 Overhead transparency properties and specifications Property Specifications Caliper 0.12 mm to 0.13 mm (4.8 mils to 5.2 mils) for HP color LaserJet printers. 0.10 mm to 0.11 mm (4.0 mils to 4.4 mils) for HP monochrome LaserJet printers. 20 Chapter 2 Guidelines for using print media ENWW
