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.
Using recycled paper and other office papers
Generally the following property guidelines apply to recycled paper.

Low moisture content (4–5%)

Suitable smoothness (100–200 Sheffield units, or 140–350 Bendtsen units, European)

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
[0.1 mm]), and paper 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).
