Tandem Tray Module (TTM): Tray 3 components
Tray 3 paper size sensor - The tray 3 paper size sensor detects if tray is inserted and senses
paper size. The tray 3 paper size sensor contains two switches,

. The size actuator,
PL 70.66 Item 2
, mounted on the tray, that works with the tray side rear,
PL 70.66 Item 3
, and
the side front,
PL 70.66 Item 4
, guides, presses these switches,
Figure 13
. The combination of
the on and off states of these switches changes the output voltage, based on which paper size
is sensed.
For tray 3 and tray 4, the tray size sensor senses A4 LEF, Letter (8.5 x 11 inch) LEF, and B5
LEF paper.

Tray 3 level sensor. The tray 3 level sensor detects that the tray has lifted the paper and is
ready to feed,

Tray 3 Feed/lift motor. The feed/lift motor is a bi-directional stepping motor. When the motor
rotates counter clockwise (CCW), it rotates the lift shaft through the gears and lifts the bottom
plate. As it rotates clockwise (CW), it drives the nudger roll and the feed roll,
