(a) Hopping
1 For hopping, the registration motor turns in direction "a" (CW 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).
