a) Functions
a-1) Recording paper pickup function
The paper feeder is driven by the main motor of the fax via the gear.
When the nPRNT signal is sent to the ECNT board from the SCNT board, the main motor
of the printer starts rotation. When the main motor reaches its prescribed speed, the paper
feeder driver PCB receives the pick-up command from the ECNT board, and the paper
feeder pick-up solenoid is turned ON. As a result, the pick-up roller, feed roller, and
separation roller are driven by the main motor rotation.
a-2) No recording paper detection function
The cassette recording paper sensor in the option feeder detects whether or not there is
recording paper in the cassette.
a-3) Recording paper size and no cassette detection function
The paper size in the cassette and whether the cassette is installed are detected by the three
switches (SW800, 801, 802) on the paper size detection board 2.
