3.16 Process Operations
3.16.01 Hopping and feeding
Hopping and feeding are affected by the registration stepper motor in the mechanism shown below.
Turning the registration motor in the "a" direction drives the hopping roller. Turning the registration motor
in the "b" direction drives the registration roller. The registration gear and hopping gear contain one-way
clutch, so that turning each of these gears in reverse direction will not be transmitted to the corresponding
roller.
Hopping
During paper hopping the registration stepper motor turns in the "a" direction (in the 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 clutch
gear.)
After the paper has turned on the inlet sensor, the paper is further advanced by a predetermined length
until the paper hits the registration roller. The brief pause in paper advancement helps to correct skew.
