4.3.4 Scan Table Drive Mechanism
The Reader Path is switched from the Printer Path, or vice versa, by
moving the Scan Table to the respective positions.
The Scan Table is driven from the Scan Table Drive Motor (M2). The
direction and speed of rotation of the Scan Table Drive Motor (M2) are
controlled by the outputs from pins 3, 4, 5 and 6 (øA, øB, øA
, and øB) of
PJ5T on the Motor Drive Board (PWB-T).
To switch from the Reader Path to the Printer Path, the Scan Table Drive
Motor M3 is energized there by moving the Scan Table toward the Printer
Position.
The Scan Table at the Reader Position is detected by the Reader Position
Sensor (PC3) and that at the Printer Position is detected by the Scan
Position Sensor (PC4).
It takes less than 1.3 sec. for the Scan Table to move from the Reader to
Printer Position.
