9.4 Removing Curling
9.4.1 Outline
The curl removing roller and the pressure roller picks paper, and bend it in the direction
opposite the direction in which the paper has curled.
Bending may be in any of three degrees, and changed by rotating the pressure cam by the
drive of the buffer pass motor.
To detect the position of the pressure cam, the upward curl phase sensor 1 (PS4) and the
upward curl phase sensor 2 (PS5) are used in normal feeding, while the downward curl
phase sensor 1 (PS6) and the downward curl phase sensor 2 (PS7) are used in reversal feed-
