Transport Fan Duty Adjustment
The transport fan below the perforated platen plates provides enough suction to keep the leading edge
flat during paper registration and cutting, and also keeps the paper flat against the platen during
printing. The machine adjusts the duty of the transport fan automatically for the size and type of paper
selected for the job.

1 Pre-registration sensor
2 Paper transport fan
3 Registration standby position
4 DRESS sensor
5 Cutter
When paper is fed:
• The pre-registration sensor (1) detects the leading edge of the paper and turns ON the fan (2).
• The DRESS sensor (3) on the left side of the carriage goes ON when it detects the leading edge of
the paper and switches operation of the fan to Duty 1.
• The paper transport fan remains in the Duty 1 phase while the paper feeds 79 mm past the
registration standby position (4). This provides maximum suction to keep the leading edge of the
paper flat.
• When the leading edge of the paper exceeds 79 mm of feed, the motor enters the Duty 2 phase.
• When the paper reaches the cutting position, the fan enters the Duty 3 phase.
