Paper Feed Mechanism

ACSF (MP-21C option)
When the line feed motor is driven in the reverse direction (reverse rotation) to the normal
paper feeding direction, the change-over 1 frame moves to engage the separation roller
gear via the idler gear. The separation roller rotates in the paper separation direction
(normal rotation) and separates a sheet of paper. The separation roller rotates with the
paper feeding operation and returns to the initial position and is registered by the paper
feed pressure spring behind the separation roller gear.
Separated paper is fed to the contact point of the Main roller and the Pressure roller by
the Pick-up roller where the top of the paper is registered.
After the paper is registered, the Paper feed motor is driven in the paper feeding direction
(normal rotation) and paper is fed by the Main roller and the Pressure roller.
After printing, paper is ejected by the Paper eject roller and the Star wheels.
