12-6. Universal Tray (2nd Drawer) Paper Size Detection

The 2nd Drawer is a Universal Tray that automatically detects the size of the paper
loaded in it. Both the length (in the feeding direction) and width (in the crosswise
direction) of the paper are detected and the copier CPU determines the paper size
based on the combination of the two readings. The width of FLS and other sizes
(13" or 14" in the feeding direction) should, however, be set using the Tech. Rep.
Choice function.
The paper length (in the feeding direction) is detected by Paper Size Detecting
Switch which are actuated or deactuated by the lever moved in phase with the Trail-
ing Edge Stop.
The paper width (in the crosswise direction) is detected by 2nd Drawer Paper Size
Detecting Resistor mounted directly under the drawer, to the rear, beside the right
rail. The resistance of Detecting Resistor is varied as the rack of the Edge Guide
for the 2nd Drawer pushes the resistor.
