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.
