OPERATIONS

• The Paper Feed Motor (M1) drives the Pick-up Roller [8] and Feed Roller [6] to take up and

feed a sheet of paper into the main body.

• Then, the Vertical Conveyance Motor (M2) transports the paper through the vertical convey-

ance section.

• The Pick-up Roller takes up sheet of paper and the Feed and Separation Rollers [5] ensure

that only one sheet of paper is separated and fed into the main body.

• When the Tray is slid in, the lever [7] is pushed to lower the Pick-up Roller.

• The Upper Limit Sensor (PS4) [9] then detects the upper limit position when the paper lifting

plate is raised.

• The Paper Empty Sensor (PS3) [1] detects when paper in the Main Tray runs out.
