22.3.1

Paper transport control

• The paper exit/switchback roller is driven by the switchback motor.
• The duplex transport roller/1,2,3 are driven by the duplex transport motor.
• In the first print cycle in duplex mode, the paper transported from the fusing section is
transported to the paper exit direction. When the paper reaches a predetermined posi-
tion, the paper exit/switchback roller rotates backward to convey the paper to the duplex
transport roller/1.
• When a predetermined period of time elapses after the switchback motor rotates back-
ward, the duplex transport motor starts rotating and duplex transport roller/1,2,3 turn to
transport the paper into the duplex section.
• When a predetermined period of time elapses after the leading edge of the paper passes
the duplex paper passage sensor, the duplex transport motor stops running and the
duplex transport roller/1,2,3 stop rotating.
