Media Guidelines
Print media is paper, transparencies, labels, envelopes, coated paper and several other types. The
printer prints on a variety of print media. Selecting the appropriate print media for the printer helps
avoid printing problems. This chapter describes how to select, store, and load print media.
For the best results in color, a 75 g/m² (20 lb.) xerographic, long grain paper is recommended. For the
best results in black and white, use 90 g/m² (24 lb.) xerographic, long grain paper.
When loading paper, identify the recommended print side on the paper package, and load the paper
accordingly.
Paper Characteristics
The following paper characteristics affect print quality and printer reliability. Use these guidelines
when evaluating the customer’s paper stock.
Weight
The trays automatically feed paper weights from 60 to 220 g/m² (16 to 32 lb. bond) grain long. Paper
lighter than 60 g/m² (16 lb.) might not feed properly, and could cause paper jams. For best
performance, use 75 g/m² (20 lb. bond) grain long paper.
Curl
Curl is the tendency of media to curve at its edges. Excessive curl can cause feeding problems. Curl
usually occurs after the paper passes through the printer, where it is exposed to high temperatures.
Storing paper unwrapped in humid conditions, even in the paper tray, can contribute to curling prior to
printing and cause feeding problems.
Smoothness
The degree of surface smoothness directly affects print quality. If the paper is too rough, the toner
does not fuse to the paper properly, resulting in poor print quality. If the paper is too smooth, it can
cause feeding problems. Smoothness between 150 and 250 Sheffield points produces the best print
quality.
Moisture Content
The amount of moisture in the paper affects both print quality and the ability of the printer to feed the
paper properly. Paper should remain in its original packaging until loaded. This limits the exposure of
the paper to moisture changes that can degrade its performance.
