1.2. Ink Jet Operation
1.2.1. Paper Feed Mechanism
The paper feed mechanism consist of the paper feed system, paper eject system, and
the paper setting system.
(1)The paper feed system consists of the ACF shaft gear, separate roller, ACF shaft
locker, locker spring, idle gears 1, 2, 3, and 4, PF roller gear, changer lever 1 and 2,
spring, and the line feed motor.
Paper feed system ACF(Auto cut-sheet feeder)
When the paper feed motor is driven in the opposite direction (reverse rotation) of the
paper feeding, the change lever 1 moves to engage the ACF shaft gear via the idle
gear. The separate roller rotates in the paper separation direction (normal rotation)
and separates a sheet of paper. The separate roller rotates with paper feeding
operation and returns to the initial position. Separated paper is fed to contact PF
roller and the pressure roller by the separate roller where the top of the paper is
registered.
