4.4 TRAY SHIFTING
4.4.1 TRAY SHIFT MECHANISMS
Tray 1 (Upper Tray)
In sort/stack mode, tray 1 [A] moves from side to side to separate the printed sets.
The tray 1 shift motor [B], inside the shift tray, controls the horizontal position of
tray 1 through the timing belt [C] and gear disk [D].
After one print set is delivered to tray 1, the shift motor turns on, driving the gear
disk and the arm [E], and the tray drive unit moves to one side.
Two shift sensors [F] detect when to stop this side-to-side movement. There is a
cut-out in the gear disk. The shift tray moves in one direction until one of the shift
sensors detects the cut-out. Then the shift tray stops.
The next set of prints is then delivered, and the gear disk is turned in the opposite
direction until the other shift sensor is activated.
