Adjusting for paper curl

Each sheet of paper has a natural curve called the curl. Storing or using the paper under humid conditions may increase the curl. When too much curl causes paper handling problems, adjust the decurler in the processor. The decurler flattens the paper after fusing.

Measuring the paper curl

1.Program and print five 1-sided, 8.5 x 11 inch (216 x 279 mm) sheets to the top tray.

NOTE: Keep the image toward you, as shown in Figure 3-5.

2.Measure the amount of curl in the prints by holding the five prints in the top center of the short edge.

Figure 3-5 Measuring the paper curl

3.Place the bottom edge of the prints over the paper curl measurement chart in this guide.

•If the print curl on the printed paper measures between +1 and - 2, do not change the decurler setting.

•If the curl is between +2 and +3, or - 3 and - 4, refer to the procedure, "Adjusting the decurler lever," in this section.

NOTE: Superior performance for greater than substance 32 (120 g/m2) can be achieved between +1 and -1 curl.
