(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 advence, 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.)
(b) Feeding
1 When hopping is completed, the registration motor turning in direction "b"
(counter-clockwise direction) drives the registration roller to advance the paper
(in this case, the hopping gear also turns, but the hopping roller is prevented
from turning by the one-way bearing.)
2 The paper is further advanced in synchronization with the print data.
