Choosing preprinted forms and letterhead
Use the following guidelines when selecting preprinted forms and letterhead paper for the printer:
Use grain long papers for best results.
Use only forms and letterhead printed using an offset lithographic or engraved printing
process.
Choose papers that absorb ink, but do not bleed.
Avoid papers with rough or heavily textured surfaces.
Use papers printed with heat-resistant inks designed for use in xerographic copiers. The ink must
withstand temperatures of 225°C (437°F) without melting or releasing hazardous emissions. Use inks
that are not affected by the resin in the toner. Inks that are oxidation-set or oil-based should meet these
requirements. Latex inks might not meet these requirements. If you are in doubt, contact your paper
supplier.
