 [A]: Decurl unit
 [B]: Exit unit
 [C]: Paper
If a concave folded corner or concave curl occurs, use the lower transport path. There is a large
diameter roller in direction of curling. If the amount of curl is in specification, the angle of which output
sheets contact with the large diameter roller becomes 60 degrees or less, so that a folded corner no
longer occurs when using the decurl unit.
Solution:
1. Check the condition of a folded corner on output sheets.
 If the corner of sheet is creased completely, the folded corner occurs at the spot which is
inside the machine and in the paper path before the decurl unit.
(It occurs on somewhere on the Trans timing roller, fusing unit, or heat pipe.)
 If the corner of sheet is not completely creased, proceed to Step 2.
2. Disconnect subsequent peripheral devices from the machine and feed paper through the machine.
 If a folded corner occurs when using the main machine only, the folded corner is caused by the
decurl unit. Follow the flowchart below. (Perform the curl correction from the control panel.)
 If a folded corner does not occur when using the main machine only, a folded corner is caused
by the transfer part to peripheral devices. In this case, check and adjust the height of the
transfer part so that the main machine and peripheral devices are connected horizontally. If
this does not resolve the problem, follow the flowchart below.
