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 24 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 230°C (446°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 230°C (446°F)
without melting or releasing hazardous emissions.
Unacceptable paper examples
Test results indicate that the following paper types are at risk for use with laser printers:
• Chemically treated papers used to make copies without carbon paper, also known as carbonless
papers
• Preprinted papers with chemicals that may contaminate the printer
• Preprinted papers that can be affected by the temperature in the printer fuser
• Preprinted papers that require a registration (the precise location on the page) greater than ± 2.3 mm
(± 0.9 in.), such as optical character recognition (OCR) forms. 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
• Recycled papers that fail EN12281:2002 (European testing)
• Paper weighing less than 60 g/m
2
(16 lb)
• Multiple part forms or documents
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
percent. Most label manufacturers recommend printing in a temperature range of 18–24°C (65–75°F)
with relative humidity between 40 and 60 percent.
• Store paper in cartons, on a pallet or shelf, rather than on the floor.
• Store individual packages on a flat surface.
