10-2. Lower Feeder Unit (Option)
(1)Paper Take-Up Mechanism
•Since there is no drive motor installed, the drive for paper take-up and transport (supplied from M1) is transmitted through a drive coupling gear from the printer.
•The same paper take-up mechanism is employed as that of the Multi-Purpose Tray, except that paper separator fingers are used, instead of the separator roll with a torque limiter, for paper separation.
•The Lower Feeder Take-Up Solenoid (SL7) is controlled from the printer through the
Lower Feeder Control Board (PWB-A) of the Lower Feeder Unit.
(2)Paper Empty Detection
•A paper-empty condition is detected by the Lower Feeder Paper Empty Sensor (PC16).
•When there is paper, the actuator is raised to block the sensor.
•When there is no paper, the actuator is lowered to unblock the sensor.
