When printing on card stock:

• Make sure the Paper Type is Card Stock.

• Select the appropriate Paper Texture setting.

• Be aware that preprinting, perforation, and creasing may significantly affect the print quality and cause jams or

other paper handling problems.

• Check with the manufacturer or vendor to ensure that the card stock can withstand temperatures up to 240°C

(464°F) without releasing hazardous emissions.

• Do not use preprinted card stock manufactured with chemicals that may contaminate the printer. Preprinting

introduces semi‑liquid and volatile components into the printer.

• Use grain short card stock when possible.

Paper guidelines

Selecting the correct paper or specialty media reduces printing problems. For the best print quality, try a sample of the

paper or specialty media before buying large quantities.

Paper characteristics

The following paper characteristics affect print quality and reliability. Consider these characteristics when evaluating

new paper stock.

Weight

The printer trays can automatically feed paper weights up to 120‑g/m

(32‑lb) bond grain long paper. The multipurpose

feeder can automatically feed paper weights up to 163‑g/m

(43‑lb) bond grain long paper. Paper lighter than

60 g/m

(16 lb) might not be stiff enough to feed properly, causing jams. For best performance, use 75‑g/m

(20‑lb)

bond grain long paper. For paper smaller than 182 x 257 mm (7.2 x 10.1 inches), we recommended to use 90 g/m

(24 lb) or heavier paper.

Note: Two‑sided printing is supported only for 60–90‑g/m

(16–24‑lb) bond paper.

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 printer, where it is exposed to high temperatures. 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 quality. If paper is too rough, then toner cannot fuse to it properly. If paper is

too smooth, then it can cause paper feeding or print quality issues. Always use paper between 100 and 300 Sheffield

points; however, smoothness between 150 and 250 Sheffield points produces the best print quality.

Moisture content

The amount of moisture in paper affects both print quality and the ability of the printer to feed the paper correctly.

Leave paper in its original wrapper until it is time to use it. This limits the exposure of paper to moisture changes that

can degrade its performance.
