Curl

Curl is the tendency for paper to curl at its edges. Excessive curl can cause paper feeding problems. Curl can occur
after the paper passes through the prin ter, where it is exposed to high tempe ratures. Storing paper unwrapped in
hot, humid, cold, or dry conditions, even in the trays, can contribute to paper curling prior to printing and can cause
feeding problems.

Smoothness

Paper smoothness directly affects print q uality. If paper is too rough, toner cann ot fuse to it properly. If paper is too
smooth, it can cause paper feeding or prin t quality issues. Always use paper between 100–300 Sheffield points;
smoothness between 150–250 Sheffield points produc es the best print quality.

Moisture content

The amount of moisture in paper affects bo th print quality and the ability of the pr inter to feed the paper correctly.
Leave paper in its original wrapper un til it is time to use it. This limits the exposur e of paper to moisture changes that
can degrade its performance.
Condition paper before printing by storing it in its origi nal wrapper in the same environ ment as the printer for 24 to
48 hours before printing. Extend the time several days if the storage or transportation environment is very different
from the printer environment. Thick paper may also require a longer conditioning period.

Grain direction

Grain refers to the alignment of t he paper fibers in a sheet of paper. Gr ain is either grain long, running the length of
the paper, or grain short, running the width of the paper.
For 60–90 g/m2 (16–24 lb bond) paper, grain long paper is recommended.

Fiber content

Most high-quality xerographic paper is m ade 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 car bonless 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 registra tion (the precise print location on the pa ge) greater than ±2.3 mm
(±0.9 in.), such as optical character recognition (OCR) forms
In some cases, registratio n can be adjusted with a software applicat ion to successfully print on these fo rms.
Coated papers (erasable bond), synthetic papers, thermal papers
Rough-edged, rough or heavily textured surfa ce 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
