surface.
Selecting 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 toner or the silicone in the fuser. Inks that are oxidation-set or
oil-based should meet these requirements; latex inks might not. If you are in doubt, contact your
paper supplier.
Preprinted papers such as letterhead must be able to withstand temperatures up to 225°C (437°F)
without melting or releasing hazardous emissions.
