This section explains how two sheets of A4 paper are fed for duplex printing.
1) When the predetermined time lapses after the first paper is supplied, the reversal motor (M1002) starts rotating to feed the paper toward the reversal tray.
Immediately after the leading edge of the paper is detected by the delivery sensor, the duplex flapper solenoid turns on to feed the paper to the duplex unit. The
duplex flapper solenoid turns off immediately after the trailing edge of the paper is detected by the delivery sensor.
