Paper and specialty media guide 117

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 or lesser than +/‑2.5 mm (+/‑0.10 inch), 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/m2 (16 lb)

•Multiple‑part forms or documents

Selecting paper

Using the appropriate paper prevents jams and helps ensure trouble‑free printing.

To help avoid paper jams and poor print quality:

•Always use new, undamaged paper.

•Before loading paper, know the recommended printable 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 tray; 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/m2 (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.
