Paper and specialty media guidelines
•
Suitable smoothness (100–200 Sheffield units, or 140–350 Bendtsen units, European)
Note: Some much smoother papers (such as premium 24 lb laser papers, 50–90 Sheffield units) and much
rougher papers (such as premium cotton papers, 200–300 Sheffield units) have been engineered to work very
well in laser printers, despite surface texture. Before using these types of paper, consult your paper supplier.
• Suitable sheet-to-sheet coefficient of friction (0.4–0.6)
•
Sufficient bending resistance in the direction of feed
Recycled paper, paper of lower weight (<60 g/m
that is cut grain-short for portrait (or short-edge) fed printers may have lower bending resistance than is required for
reliable paper feeding. Before using these types of paper for laser (electrophotographic) printing, consult your paper
supplier. Remember that these are general guidelines only and that paper meeting these guidelines may still cause
paper feeding problems in any laser printer (for example, if the paper curls excessively under normal printing
conditions).

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%. Most label
manufacturers recommend printing in a temperature range of 18 to 24°C (65 to 75°F) with relative humidity between
40 and 60%.
•
Store paper in cartons when possible, on a pallet or shelf, rather than on the floor.
•
Store individual packages on a flat surface.
•
Do not store anything on top of individual paper packages.
