2.2 Paper Transfer
2.2.1 Paper supply
The paper pick-up roller picks up one sheet of paper from the paper tray every time it is
rotated and feeds it to the paper feed roller.
Fig. 3-32
The paper is gripped between the paper pick-up roller and the separation pad and separated
into individual sheets.
The pick-up roller is directly connected to the clutch mechanism, whose rotation is stopped by
the stopper arm. When the pick-up solenoid is activated, the clutch mechanism is engaged by
the solenoid action and the paper pick-up roller is driven. The paper drawn out of the tray by
the pick-up roller pushes against the regist front actuator and the paper top position/absence
of paper is detected by sensing the motion of the actuator.
Paper particles generated by friction between the separation pad and the paper feed roller are
removed by the pressure roller of the paper tray. The removed paper particles are gathered to
the dust collecting space of the paper tray. Paper particles generated at the paper feeding
path are removed by the first feed pinch roller which comes into contact with the printing area.
The removed paper particles are moved to the left and right hand side by means of the upper
auger Y which is located near the first feed pinch roller, then they are stored in the dust
collecting space of the printer.
