Appendix B: Paper specifications andrecommendations
GCC Technologies recommends the following materials for use with your printer. GCC
does not assume liability for materials used with the printer that are not listed below.
Printing on standard papers
Your GCC printer prints on most kinds of paper stock, including most color stocks and
letterhead. The printer produces best results on standard 20-pound (75 g/m2) copier-type
paper; however, paper weights from 16-lb. to 28-lb. (60 g/m2 to 105 g/m2) should also
provide good results.
To produce even clearer, sharper images, use paper with a surface that is smoother, but not
shinier, than photocopy paper. Some companies offer paper specifically designed for laser
printers.
Printing on letterhead
Letterhead should conform to the weight and surface characteristics specified in the previ-
ous section. Also, keep the following points in mind when printing on letterhead:
•Temperature: Some letterheads use low-temperature dyes that vaporize and smear at
high temperatures. Many letterheads that have a slick texture use a heat bonding
process called thermography that bonds the print to the paper. Letterheads produced
with this technique may “unbond” in the printer, causing damage.
•Paper Texture: Highly textured paper may not print evenly.
•Paper Finish: Paper that is extremely shiny does not work well.
Printing on envelopes
Use envelopes that are smooth (but not slick) and have rectangular or square flaps (rather
than a triangular flap).
Envelopes should be fed from the multipurpose feeder. There is also an envelope tray
available as an option. For more information, see “Optional accessories.”
WARNING: The printer uses heat in the printing process. Do not use material that may
melt inside the printer, such as Tyvek® envelopes. Serious damage to the printer may result.
Printing on overhead transparency film
Use transparencies recommended for dry toner machines. Other transparencies may cause
damage to the printer.
