Product Technical Overview
When either of the paper trays 1, 2, 3 or 4 are fully inserted into a powered on machine the
state of their tray level sensor is checked by a component control PWB. The STM, 1TM, 3TM
and TTM all have an integral control PWB. However, the components of tray 1 are controlled
by the drive PWB, PL 1.10 Item 3. If the signal tray level sensor off is detected by the control
logic, the feed/lift motor is activated to run in the counter clockwise direction (CCW). Thereby,
elevating (via a gear train and lift shaft) the bottom plate and paper stack of that tray up to the
paper feed position. In the feed position the elevated paper stack actuates the tray level sensor
to signal on. When tray level sensor on signal is detected by the control logic, the feed/lift motor
begins to rotate in a clockwise (CW) direction, driving the nudger and feed rolls and thereby
feeding the top sheet towards the takeaway rolls, Figure 6.
During paper feeding the tray level sensor is continuously monitored. When the signal tray
level sensor signal off is detected, the control logic determines that it cannot feed the next
sheet. The feed/lift motor, that is rotating CW during feed, then begins rotating CCW a prede
-
termined time after the end of the feed operation. Thereby, recommencing elevation of the
paper stack to the paper feed position, then the feed cycle begins again, Figure 6.
Figure 6 Tray control components
The tray level sensor, no paper sensor and pre feed sensor are all integral to the feeder
assembly, Figure 7. The feed/lift motor is part of the feeder assembly, Figure 8. Only paper tray
1 has a pre feed sensor. This sensor is use to detect paper mis feeds and paper jams.
