Pinch Roller Ass'y Home Position and Movement

The F/R pinch sensor detects the home position of the two pinch roller assemblies.
When power is switched on or pressing the All Reset Button moves the pinch roller ass'y s to the home
position.
The pinch roller position during printing is determined by the paper width potentiometer on the paper feed
tray, and the sliding of the pinch rollers to a new position is made when the START key is pressed for
printing operation.
The pinch rollers stay in one set position throughout the printing. When the paper size is changed on the
paper feed tray, the pinch rollers move to the new position when the START key is pressed to continue the
printing operation.
The pinch slide ass'y is released or made in contact by the pinch roller release motor. The position of the
pinch slide ass'y is checked by the pinch roller release sensor.
The pinch rollers are released during the sliding movement or when in standby, and are in contact
position during the printing.
5. Paper Receiving Tray Mechanism
