(a) Hopping
1
Hopping turns the resist motor in the "a" direction (in the CW direction) and drives the
hopping roller to advance the paper until the inlet sensor turns on. (In this case, the resist
gear also turns, but the resist roller is prevented from turning by the one-way clutch gear.)
2
After the paper has turned on the inlet sensor, the paper is further advanced by a predeter-
mined length until the paper hits the resist roller. (The skew in the paper can thus be
corrected.)
CW = Clockwise
