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 ma-
chine determines which size cassette
is installed by monitoring the three mi-
croswitches in the detector. The
machine informs the customer with
the Add Paper indicator if the paper
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
•
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.
