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.
