(b) Feeding

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).

The paper is further advanced in synchronization with the print data.
(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).
