Paper Empty Detection

• There is a Paper Empty Sensor provided on the 2nd Drawer Control Board. It detects a
paper empty condition of the cassette.
• When paper is loaded, the actuator is raised and blocks the sensor.
• If there is no paper loaded, the actuator drops in the hole in the Paper Lifting Plate, thus
unblocking the sensor.

Cassette Type Detection

• The Paper Feed Cassette is provided with the Cassette Type Detection Switch.
• When the cassette is inserted into the printer, the switch pusher provided on the right-
hand side of the cassette pushes the lever according to the paper size, turning ON the
switch.
• The Cassette Type Detection Switch consists of three switches.
The combination of these switches that turn either ON or OFF allows the printer to deter-
mine the cassette type (paper size).
