6 VERTICAL TRANSPORT SECTION

1. Vertical Transport Drive Mechanism

•

The Vertical Transport Rollers are driven by the Vertical Transport Motor.

•

The driving force of the Vertical Transport Motor is transferred through the belt to the Vertical Transport Rollers which feed the paper from the Paper Drawers to the copier .

Vertical Transport Roller 2

Vertical Transport Roller 1

2. Vertical Transport Motor Control

•

Vertical Transport Motor, which is a stepping motor, is driven by the output signals from pins 1, 2, 17, and 4 of IC9A on the cabinet’s Master Board which is in turn controlled by the Master Board of the copier. These signals energize the two coils in the V ertical Transport Motor.

7 PAPER TAKE-UP/FEEDING SECTION

7-1. Paper Take-Up Mechanism

(1) Paper Take-Up Mechanism

•

The paper take-up and feeding mechanism takes up paper from a drawer and feeds it to the Vertical Transport Roller.

•

The take-up mechanism is driven by 3rd and 4th Drawer Paper Take-Up Motors.

•

Each paper take-up mechanism consists of a T ak e-Up Roll, Feed Roll and Separator Roll with torque limiter.

•

The Separator Roll is controlled by the torque limiter so that it wil l not transport more than one sheet of paper at a time.

•

The wider Take-Up Roll assures straight paper transport.

(2) Paper Separating Mechanism

•

The paper separating mechanism ensures that only the top sheet of paper is fed in by separating the second sheet of paper from the top one.

•

This is accomplished by the difference in friction coefficient between the Feed and Separator Rolls.

•

When only one sheet of paper is fed, the friction coefficient on the top side of the paper is equal to that on the underside. Driven by the Feed Roll, the paper drives

Feed Roll

the Separator Roll. This causes the paper to be sent to the Vertical Transport Section.

•

Paper

The friction coefficient varies for different ambient conditions and types of paper

being used, which often causes the Separator Roll to be stationary.

Driven or stationary

•

Since the coefficient of friction between the top side of the first sheet of paper and the

Feed Roll

Feed Roll is greater than that between the

first and second sheets of paper, the first 1st Sheet of Paper

sheet of paper is fed into the copier by the

Feed Roll.

Since the friction coefficient between the 2nd Sheet of Paper

Separator Roll

Stopped

second sheet of paper and the Separator

Roll is greater than that between the first

and second sheet of paper, the Separator

Roll is not driven and holds the second

sheet of paper.

(3) Paper Pressure Releasing Mechanism

•

If the Drawer is pulled out while the paper is between the Feed Roll and the Separator Roll, the paper is left in the unit. Removal of the paper is difficult. With this cabinet, opening the drawer automatically disengages the paper and Paper Take-Up/Feed Roll.

•

The Paper Pressure Releasing Mechanism makes it easier to remove a sheet of paper held between the Feed Roll and Paper Separator Roll by just opening the drawer.

•

When the Drawer is pulled out, the paper Lifting Plate is lowered and the pressure release rail pushes down the Separator Roll, disengaging the Feed Roll from the Separator Roll.

(4) Paper Take-Up Roll Retraction Mechanism

•

Pulling the Drawer out causes the Pressure Release Lever to push up the Paper Take-Up Roll/Feed Roll, freeing the paper from the Paper Take-Up Roll.
