• Preprinted papers that require a registration (the precise print location on the page) greater than ±2.3 mm
(±0.9 in.), such as optical character recognition (OCR) forms
Note:
In some cases, registration can be adjusted with a software application to successfully print on
these forms.
• Coated papers (erasable bond), synthetic papers, thermal papers
• Rough-edged, rough or heavily textured surface papers, or curled papers

Selecting paper
Using appropriate paper prevents jams and helps ensure trouble-free printing.
To help avoid jams and poor print quality:
•
Always
use new, undamaged paper.
• Before loading paper, know the recommended print side of the paper. This information is usually indicated
on the paper package.
•
Do not use paper that has been cut or trimmed by hand.
•
Do not mix paper sizes, types, or weights in the same source; mixing results in jams.
•
Do not use coated papers unless they are specifically designed for electrophotographic printing.
Selecting preprinted forms and letterhead
Use these guidelines when selecting preprinted forms and letterhead:
•
Use grain long for 60 to 90 g/m
2
(16 to 20 lb) weight paper.
•
Use only forms and letterhead printed using an offset lithographic or engraved printing process.
•
Avoid papers with rough or heavily textured surfaces.
Use papers printed with heat-resistant inks designed for use in xerographic copiers. The ink must be able to
withstand temperatures up to 190°C (374°F) without melting or releasing hazardous emissions. Use inks that
are not affected by the resin in toner. Inks that are oxidation-set or oil-based generally meet these requirements;
latex inks might not. When in doubt, contact the paper supplier.
Preprinted papers such as letterhead must be able to withstand temperatures up to 190°C (374°F) without
melting or releasing hazardous emissions.
