PAPER FEED
Paper Feed Drive
[E]
[F]
[I]
The main motor drives the pick-up and feed mechanism through the paper pick-up
drive gear [D].
To pick up paper, the tray paper feed solenoid [A] turns on and the gear stopper [B]
comes off the paper feed roller gear [C]. This gear does not move immediately,
because the gap in the teeth prevent it from engaging the drive gear [D]. It is first
turned clockwise by a spring until its teeth engage with the drive gear, which now
drives the paper feed roller [E].
At the same time, the cam behind the paper feed roller gear moves the stopper
release lever [G], and this releases the bottom plate stopper [H]. The bottom plate
can then lift the top of the paper stack to the correct height for paper feed.
This machine uses a feed roller and friction pad mechanism. The friction pad [F]
only allows the top sheet to feed to the relay roller [I].
After one turn, the paper feed roller gear stops because the part of the gear without
teeth is now back at the starting position, opposite the pick-up drive gear. The gear
stopper and bottom plate stopper also return to their previous positions
Then the relay rollers feed the paper to the transfer area.
NOTE: If the gear stopper comes off the paper feed roller gear as a result of shock
or vibration and paper is placed in the tray, the machine starts to feed
paper as soon as it is turned on. To fix this problem, remove all paper from
the paper tray then turn on the machine.
Paper End Detection
This is the same as for the G031. There is no near-end detection.
