whose surface is curled (maximum allowable curl is 5mm).

face, pull the insertion side of document center of the operation panel.

recording sheet. The PICKUP ROLLER feeds one by one from the
top sheet.
2) The recording sheet contacts the P-IN SENSOR.
3) The FEED ROLLER rotates in the reverse direction of paper feed
(refer to the figure of PICKUP ROLLER). The tip of recording sheet
is set parallel to the FEED ROLLER when it reaches to the FEED
ROLLER and the PRESS ROLLER after through the PICK UP
ROLLER.
4) Then the FEED ROLLER rotates in the paper feed direction to feed
the recording sheet downwards. (refer to the figure of PAPER
FEED)
5) The CARTRIDGE prints the recording sheet, which is then ejected
by the EXIT ROLLER and STAR WHEEL.
