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°.
