(1) The paper is gripped between the separation roller and separation pad and separated into
individual sheets. The separation roller is connected to the gear 52 P/R.
(2) The section of the gear 52 P/R, where there is no cog, is normally fixed at the position as
shown in the figure below by the P/R solenoid ASSY.
(3) Therefore, the main motor drive is not transmitted to the gear 52 P/R.
(4) When the paper is fed, the P/R solenoid ASSY is activated first.
(5) Then, the gear 52 P/R is pulled by the spring extension P/R so that the gears are engaged.
(6) The main motor drive is transmitted to the gear 52 P/R, and the separation roller is turned.
The paper drawn out of the paper tray pushes against the regist front actuator, and the paper top
position or absence of paper is detected by the actuator movement. The tail edge actuator detects
the end of the paper fed.
