2.Detailed Descriptions

Paper Feed

The bypass tray can hold 500 sheets of standard weight paper.

The bypass tray uses the standard FRR (Feed and Reverse Roller) feed system. When the job starts,

the feed motor [A] switches on and rotates the pick-up roller [B]. At the same time, the pick-up solenoid

[not shown] switches on and lowers the pick-up roller. The lift motor [C] switches on to raise the stack

until the top of the stack reaches the correct feed level. At that time, the paper pushes the pick-up roller

down. When the actuator [not shown] goes out of the lift sensor [not shown], the lift motor stops.

The pick-up roller picks up and feeds the first sheet to the feed roller [D] and separation roller [E]. When

the feed sensor [not shown] detects the leading edge of the sheet, the pick-up solenoid raises the pick-

up roller and the feed roller feeds the sheet.

Unlike the separation rollers in the LCT, the separation roller always remains in contact with the feed

roller above.

The transport motor [F] then feeds the paper into the bypass tray, and the relay motor [G] feeds the

paper out of the bypass tray, and into the machine through the LCT.

When the pick-up roller [B] lowers far enough to go into the lift sensor, the lift motor switches on to raise

the bottom plate until the actuator goes out of the lift sensor again and switches off the lift motor. This

movement is repeated to maintain the correct height of the stack for paper feed.

Actuator [H] is used by the height sensors, to detect the amount of remaining paper.
