Output Reverse Control
Primary bin media pick is initiated by reverse motion of LF motor for a specified (small)
angle. As our output drive is connected directly to LF motor , star wheels tend to rotate in
reverse direction . This pulls back the media which is to be ejected to the print zone
which may cause jamming. (Note: Media ejection is done simultaneously along with Pick
to increase throughput). Hence we need a mechanism which should be able to disengage
output star wheel drive during the reversal of LF motor. This is taken care by introducing
Rocking gear as a part of the output drive . Rock gear engages with its mating gear only
when LF motor rotates in forward direction and disengages in reverse direction. Rock
gear is mounted on the arm-rocker which is stopped in defined positions in both
directions by Left-support wall. Arm-rocker disengagement angle is 20°.
