Fiber content
Most high
‑quality xerographic paper is made from 100% chemically treated pulped wood. This content provides the
paper with a high degree of stability resulting in fewer paper feeding problems and better print quality. Paper containing
fibers such as cotton can negatively affect paper handling.
Unacceptable paper
The following paper types are not recommended for use with the printer:
• Chemically treated papers used to make copies without carbon paper, also known as carbonless papers, carbonless
copy paper (CCP), or no carbon required (NCR) paper
• 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 print 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)
• Paper weighing less than 60 g/m 2 (16 lb)
• Multiple
‑part forms or documents
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. This information is usually indicated on the package.
• Do not use paper, paper labels, or card stock that has been cut or trimmed by hand.
• Do not mix 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 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.
