Theory of Operation
Printer Control
Paper Size Detection
The paper size detection for Trays 2 and 3 is determined by three paper size
switches in each paper tray slot. The switch condition is set by moving the
paper guide in the tray. This in turn sets the plastic “fingers” on the side of the
paper tray to a specific position that activates the correct switch combination
for the selected paper size.
Note
On
: The Actuator is pushing the Size Switch.
