2.3.3 Process Operation Descriptions

(1) Hopping and Feeding
Hopping and feeding motions are actuated by a single registration motor in the mechanism as shown below:
The registration motor turning in direction "a" drives the hopping roller. The registration motor turning in direction "b" drives the registration roller. The registration
and hopping gears have one-way bearing, so turning any of these gears in the reverse direction will not transmit the motion to the corresponding roller.
(a) Hopping
1 For hopping, the registration motor turns in direction "a" (clockwise direction) and drives the hopping roller to advance the paper until the inlet sensor turns on
(in this case, the registration gear also turns, but the registration roller is prevented from turning by the one-way bearing).
2 After inlet sensor is turned on by the paper advance, the paper is further advanced to a predetermined distance until the paper hits the registration roller (the
skew of the paper can thus be corrected).
