• The leading edge of the paper must be fed manually from the roll unit and the sequence is
done again.
• The operator should check the roll to make sure that the clamps are locked and that the roll is
set correctly.
2. If the amount of skew is within range of pre-check, the horizontal motor ON > Carriage moves to
the leading edge detect position.
3. The roll paper feed motor and vertical motor turns ON again.
4. When the DRESS sensor detects the leading edge of the paper, it allows paper to feed 100 mm
and turns the roll paper feed motor and vertical motors OFF.
5. The horizontal motor turns ON and moves the carriage to the left side of the machine.
6. The roll paper feed motor and vertical motor both turn ON and feed the paper 60 mm.
7. Now, the roll paper feed motor reverses while the vertical motor continues to feed the paper
forward. This takes up any slack in the paper to correct skew, and then both motors turn OFF.
8. Paper transport fan remains ON.
9. The horizontal motor turns ON and moves the carriage to the right edge and stops > DRESS sensor
detects the right edge again.
10. If the amount of deviation is within ±5 mm, paper registration ends and the sequence continues
without interruption.
If the deviation is not within ±5 mm, the paper is released, the vertical motor and roll paper feed
motors reverse feed, and the paper rewinds onto the roll.
11. The paper feed sequence continues from Step 2 of above.
Paper Size Detection
1. The horizontal motor > ON and makes a complete pass from right to left, back to the right and
stops.
2. The DRESS sensor detects the left edge of the paper on the platen.
3. The machine records the readings of the horizontal encoder for the right and left edges of the
paper. This is done to confirm the paper size with the selection done with an external coin operated
device if one is attached.
Paper Fan Duty is Adjusted
1. The duty of the transport fan is automatically adjusted for the size of the paper and type of paper
selected for the print job.
2. The suction of this fan below the platen keeps the leading edge of the paper flat against the platen
during paper registration and prevents the paper from floating free during printing.
Paper Cutting
If the operator selected paper cutting, the cutter cuts the paper.
1. Horizontal motor ON > Carriage moves to left side of the machine and stops.
