Park fan-fold paper
1. Checks whether or not there is remaining paper.
Activates the tractor motor, monitors the sensor output, and checks whether or
not there is any paper remaining in the transport pathway. If there is paper
remaining, executes steps 2 through 9 of the preceding topic, "Eject fan-fold
paper." Otherwise, proceeds to the next step.
2. Reverses the tractor motor.
Reverses the tractor motor, and pulls the leading edge of the paper in front of the
paper back feed sensor. At this time, if the paper back feed sensor detects paper,
this is considered to be an error and the task is terminated, even if the encoder
count is below 0.
Also, when the cutting operation for remaining paper is executed, this stops the
main unit feed motor as soon as the leading edge of the paper is retracted to the
front of the paper back feed sensor.
3. Transfers to online idling state.
NOTE: Commands to request this operation cannot be received unless the paper
Feed fan-fold paper (1/2 inch)
1. Turns on the transport unit.
Activates the main unit feed motor (high-speed side) and vacuum fan.
2. Opens the face gate.
Opens the transport path to the face-up paper output tray. Controls the paper
output gate to the condition memorized in the fixed memory.
3. Activates the tractor motor.
The tractor motor always stops at the position where the encoder has detected Z
phase pulse (1 pulse / revolution), and maintains that position (detent). The
tractor motor activated here rotates once (equivalent to 1/2 inch paper transport
distance) and returns to detent condition.
5–76
