3. Paper Size and Paper End Detection
Standard Cassette/Optional Universal Cassette
The paper size detector [A] is located
at the front of the cassette.
The machine determines which size
cassette is installed by monitoring
three microswitches.
The machine informs the customer
with the Add Paper indicator if the pa-
per size cannot be detected.
When the cassette runs out of paper,
the paper end sensor actuator [B]
drops through a slot in the bottom
plate.
Selectable cassette paper sizes:
•
USA model: Letter, (Legal when
the optional Universal cassette is installed)
•
Europe model: A4, A5 sideways
•
Asia model: A4, A5 sideways, F/F4
The following diagram shows the relationship between the activated mi-
croswitches and the selected paper size.
