If the paper is curled face up, select "U Curl".
If the paper is curled face down, select "П Curl".
Depending on how much the paper is curled, specify the degree of correction by selecting "Small" or
"Large".
Paper of Thickness 0 is Curled When Delivered
Sheet bending may occur when paper of Thickness 0 is delivered.
Edge of Sheet Bends Downward (Convex
Curling)
Edge of Sheet Floats and Bends Upward (Concave
Curling)
 If back curling (convex curling) occurs, the leading edge of the delivered sheet droops. In this case,
because the contact angle between the leading edge of the sheet and tray becomes steep, the
leading edge may bend downward. This is likely to occur if the sheet is ejected with face up.
 If face curling (concave curling) occurs and the curl size is large (the height of curl = 15 mm or
more), the leading edge of the sheet may float and bend upward.
* Both convex and concave curling prevent subsequent sheets from stacking properly, resulting in
paper jam (JAM107/109).
Cause
This is likely to occur if:
 Paper of Thickness 0 (52.2 g/m2 or less) is used
Output sheets bend, or jam error caused by sheet bending (JAM 107/109) occurs
Frequency: Incidence rate of convex curling is 4/300
Solution
If sheet bending occurs, take the following steps:
1. Attach the support plate, and check that sheet bending occurs no longer.
If this does not resolve the problem, proceed to the next step.
