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 176 g/m
2
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 200°C (392°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 200°C (392°F)
without melting or releasing hazardous emissions.
Storing paper
Use these paper storage guidelines to help avoid jams and uneven print quality:
• For best results, store paper where the temperature is 21°C (70°F) and the relative humidity is
40%. Most label manufacturers recommend printing in a temperature range of 18 to 24°C (65 to
75°F) with relative humidity between 40 and 60%.
•
Store paper in cartons when possible, on a pallet or shelf, rather than on the floor.
