Trays 2 and 3
The universal trays 2 and 3 include end and side guides that manually adjust to the
paper loaded in the tray. These guides come into contact with the front and rear edges
of the paper and hold it in position. Paper size is determined by the position of the
switches in the Paper Size Switch assembly. The signal created by these switches
indicates the paper size setting of the guides.
