the positioning roller and return rollers. The positioning roller descends. The
positioning roller and return rollers feed the trailing edge of the paper to the right
against the bottom fences. The side fence motors switch on and jog the edges of the
sheet so that the first sheet is properly aligned.
3. The side fences return to the start position after the next sheet has feed 50 mm past
the entrance sensor.
4. Steps 2 and 3 are repeated for the next sheet.
5. In stapling mode: After the last page of the document has fed and been aligned on top
of the stack by the rear and front fences, the side fences retract and advance two more
times against the sides of the complete stack.
6. The stack is now ready to be output from the finisher. The side fences stop at the sides
of the stack and wait for the stack to be output. After output, the side fence motors
switch on and move the fences to the jog start position.
As soon as 10 sheets stack on the jogging tray in shift mode, the stack is output
regardless of whether the document has finished printing or not.
In stapling mode, the side fence that jogs the side of the stack stops and waits for
stapling to end. After stapling, the side fence motor switches on and retracts the
side fence 0.5 mm. (If the stack is centered, both fences retract 0.25 mm).
After the stack is output by the feed-out belt, the side fence motors switch on and
once again move the fences to the jog start position.
7. In the shift mode: The rear side fence does the jogging against the side of the stack,
and the front fence does not move. For the next stack, the roles of the side fences are
reversed: the front fence does the jogging and the rear fence does not move. The
operation continues to alternate for the next stacks so that each stack is shifted to the
front (or back) depending how it was jogged between the side fences. (Steps 2, 3, 6
repeat.)
In the staple mode, the steps are done in sequence (2), (3), (5), (6).
8. After the last stack of the job has been output, the main machine sends a STOP signal
to end the job, and the front and rear side fence motors switch on and the side fences
retract to their home positions.
