a) Functions
a-1) Recording paper pickup function
(From multi-purpose tray)
In case of paper pick-up from the multi-purpose tray, while the main motor rotates, the
multi-purpose tray pick-up solenoid is turned ON. Then, the multi-purpose pick-up roller
rotates, and a sheet of paper is fed into the printer section.
Up to 100 pages can be loaded into the multi-purpose tray at one time and the position of
the movable paper guides can be adjusted for recording paper.
(From cassette 1)
In case of paper pick-up from the cassette, while the main motor rotates, the pick-up
solenoid and feed roller clutch are turned ON. Then, cassette pick-up roller, cassette feed
roller, separation roller and feed rollers rotate, and a sheet of paper is fed into the printer
section.
(From cassette 2: Option)
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) Recording paper pickup jam detection function
When there is a recording paper pickup jam, this is detected by the recording pre-feed
sensor.
a-3) No recording paper detection function
When there is no recording paper in the multi-purpose tray, this is detected by the multi-
purpose tray paper sensor on the multi-purpose pickup assembly.
The cassette recording paper sensor in the feeder detects whether or not there is recording
paper in the cassette.
a-4) 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 (SW600, 601, 602) on the paper size detection board 1.
Cassette 2 (Option)
The paper size in the cassette and whether the cassette is installed are detected by the three
