(a) Hopping
1 The pulse motor turns in the arrow direction of "a" (counterclockwise) and drives the
hopping roller to move the paper until the Entrance sensor turns on. Although the one-
way gears B and C are also driven, the resist roller 2 does not turn because the
reverse rotations of the one-way clutch gears are not transmitted to the resist roller.
2 After the Entrance sensor turns on, the hopping roller keeps on feeding the paper until
it hit the resist roller 1. (This operation corrects any paper skew.)
(b) Conveying
1 After paper hopping is completed, the pulse motor turns right (in the direction of "b")
to drive the resist rollers 1 and 2. The resist rollers feed the paper until the Form
sensor turns on.
Although the one-way gear A is also driven, the hopping roller does not turn because
of the one-way clutch.
2 The paper is further fed in synchronism with the print data.
