2.2.4.2 Tractor Mechanism

Torque sent from the PF motor to the gears at the left end of the PF roller is transmitted to the tractor
gears via disengage mechanism by the release lever operation. When the release lever is set to the
tractor side, the release sensor detects the position and the torque from the ASF mechanism is
disengaged consequently.

2.2.4.3 Manual Feed Mechanism

The printer loads cut sheet and roll paper at the rear paper slot. While paper is detected by the rear PE
sensor, the CR unit is off the ASF paper feed position. Therefore paper is manually loaded even if there
is paper in ASF. This mode allows the use of paper which is not set in ASF.
