Overhead transparencies

When printing transparencies, use of tray 1 is recommended. 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.

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 poor materials or that is too thin can

easily melt in the fuser and damage the printer.

Overhead transparency materials must be compatible with the heat and pressure of the fusing

process.

The table below summarizes the overhead transparency specifications that provide the best

performance.

Table 12. Overhead transparencies specifications

Property Specifications

Caliper (thickness) 0.10 mm to 0.11 mm (4.0 mils to 4.4 mils).

Electrical surface

resistivity

2.0 to 15 by 10

ohms/square.

Fusing compatibility Overhead transparency materials must be compatible with

the heat and pressure of the fusing process. Materials

must not discolor, melt, offset materials, or release

undesirable emissions when heated to a temperature

between 175° to 230° C (347° to 446° F) for 0.1 second.
