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.
