Paper Size Detection – Trays 1 and 2
End Plate
The sensor detects the paper size. The actuator position
depends on the end plate position.
Slide 225
The sensor functions as a tray set switch and a size detector.
The three switches on the left detect paper size. The switch on the right is a
tray set sensor.
Only the length is detected directly.
The actuator has patterns of studs on the rear.
These studs turn the paper size switches on/off.
This also tells the cpu that the tray is in the machine.
The settings of SP 5-181 determine how the machine interprets the sensor
readings for paper sizes that are almost the same.
If other paper sizes are used, they must be selected with a user tool:
System Settings - Tray Paper Settings - Tray Paper Size (Tray 2).
If the fence is moved, a different set of studs moves to the switches, and the
machine detects a different paper size.
