Paper Size Detection
The end fence is interlocked with a size detection actuator in an automatic detection system which
recognizes patterns using a 4-position push switch.
Size is detected by the detection patterns of switches 1, 2, 3, and 4. Tray set is detected by another
switch.
If the machine detects a change in the outputs from the switches, the machine detects the paper size
again from the new outputs.
If the paper size is selected manually by a user setting, the automatic size detection is overridden.
No.
