CAUTION

1. Precautions for Service Jobs

•

A toothed washer and spring washer, if used originally, must be reinstalled.
Omitting them may result in contact failure which could cause an electric shock
or fire.

•

When reassembling parts, make sure that the correct screws (size, type) are
used in the correct places. Using the wrong screw could lead to stripped
threads, poorly secured parts, poor insulating or grounding, and result in a mal­function, electric shock or injury.

•

Take great care to avoid personal injury from possible burrs and sharp edges on
the parts, frames and chassis of the product.

•

When moving the product or removing an option, use care not to injure your
back or allow your hands to be caught in mechanisms.

2. Precautions for Servicing with Covers and Parts Removed

•

Wherever feasible, keep all parts and covers mounted when energizing the
product.

•

If energizing the product with a cover removed is absolutely unavoidable, do not
touch any exposed live parts and use care not to allow your clothing to be
caught in the moving parts. Never leave a product in this condition unattended.

•

Never place disassembled parts or a container of liquid on the product parts fall­ing into, or the liquid spilling inside, the mechanism could result in an electric
shock or fire.

•

Never use a flammable spray near the product. This could result in a fire.

•

Make sure the power cord is unplugged before removing or installing circuit
boards or plugging in or unplugging connectors.

•

Always use the interlock switch actuating jig to actuate an interlock switch when
a cover is opened or removed. The use of folded paper or some other object
may damage the interlock switch mechanism, possibly resulting in an electric
shock, injury or blindness.

7 PAPER TAKE-UP/FEEDING SECTION

7-1. Paper Take-Up Mechanism

(1) Paper Take-up Mechanism

•

Paper is taken up from the 3rd Drawer and fed to the Vertical Transport Roller.

•

The take-up mechanism is driven by 3rd Drawer Paper Take-Up Motor.

•

The paper take-up mechanism consists of a Separator Roll with torque limiter, Take-Up
Roll and Feed Roll.

•

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.

98.06.08

(2) Paper Separating Mechanis m

•

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.

Normal Feeding

•

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.

Feed Roll

Paper

Separator Roll

4425M107AA

Driven or stops

Driven by the Feed Roll, the paper drives
the Separator Roll. This causes the paper
to be sent to the Vertical Transpor t Sec­tion.

•

The friction coefficient varies for different
ambient conditions and types of paper
being used, which often causes the Sepa­rator Roll to be stationary.

Double Feeding

Feed Roll
1st Sheet of Paper

2nd Sheet of Paper

Separator Roll

Stops

4425M108AA

•

Since the coefficient of friction between
the top side of the first sheet of paper and
the Feed Roll is greater than that between
the first and second sheets of paper, the
first sheet of paper is fed into the copier
by the Feed Roll.
Since the friction coefficient between the
second sheet of paper and the Separator
Roll is greater than that between the first
and second sheet of paper, the Separ ator
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.

•

The Paper Pressure Releasing Mechanism makes it easier to remove a sheet of paper
that remains between the F eed Roll and Paper Separator Roll by just pressing the Paper
Descent key. When the Paper Descent key is pressed, the main tray is lowered and the
3rd Drawer is pushed forw ard by approx. 70 mm. At the same time, the pressure release
rail pushes down the Separator Roll, disengaging the Feed Roll from the Separator Roll.

7-2. Paper Take-Up Control

(1) Paper Take-Up Motor Control

•

The 3rd Drawer Paper Take-up Motor, a stepping motor , is driven by the signals from pins
1, 2, 4 and 17 of IC8A on the cabinet’s Master Board which is controlled by the Master
Board of the copier. These signals are applied to two coils of the 3rd Drawer Paper Take­up Motor.

4479T48MCB

(2) Paper Take-Up Retry Control

•

If the Paper Take-Up Sensor is not activated (does not go low) because it is not blocked
by the paper within a predetermined time after start of paper take-up, the Drawer Paper
Take-Up Motor is started again.

•

A paper misfeed results if a sheet of paper does not reach the Paper Take-Up Sensor
even after three paper take-up sequences.

98.06.08

(3) Paper Take-Up Interval Control (30 cpm Copier Only)

•

The Paper Feed Roll and Separ ator Roll may sometimes fail to separate the subsequent
sheet of paper properly and the leading edge of that paper may be beyond the Feed and
Separator Rolls inside the copier. If the next paper take-up sequence is started in this
condition, the distance between the preceding and the current sheet of paper will
become shorter than normal, resulting in a misfeed.

•

To maintain a given paper take-up interval, therefore, this copier provides the following
control. If it takes the paper more than a specified time to block (L) Paper Take-Up Sen­sor after Paper Take-Up Motor has been energized, Paper Take-Up Motor is temporarily
deenergized and, an appropriate period of time thereafter, it is energized again (paper
take-up interval control).

(4) Double Feed Paper Take-Up Control (30 cpm Copier Only)

•

Even if the Paper Take-Up Roll takes up two sheets of paper at one time, the double f eed
paper take-up control uses the second sheet of paper for the next copy cycle without
causing a paper misfeed. It eliminates a paper misfeed that would otherwise result when
two sheets of paper are taken up at once.

•

If the second sheet of paper is stationary blocking Paper Take-Up Sensor when the trail­ing edge of the first sheet of paper moves past Vertical Transport Sensor, the copier
determines that it is a double feed condition and provides double feed control.

•

If, howe ver, the second sheet of paper has reached the Vertical Transport Roller, the dou­ble feed control is not provided since the paper is fed further into the copier by the Verti­cal Transport Roller. This could result in a paper misfeed or the second sheet of paper
being fed through the copier with the first one.

(1) Main Tray Paper Lift-Up Operation

•

The Main Tray of the 3rd Drawer is raised and lowered by the Main Tray Elevator Motor
through a gear train, pulleys and 4 wires (at front and rear, two wires each).

1. Main Tray Top Level Position Detection

•

The Main Tray is at its top position when 3rd Drawer Paper Lift-Up Sensor is blocked (L).

2. Main Tray Lower Position Detection

•

The Main Tray is at its lower limit position when the Lower Position Sensor at the drive

7-9. Paper Empty Detection

•

The reflector-type photosensor on Main Tray Paper Empty Board and 3rd Drawer Paper
Empty Sensor detect a paper empty condition on the Main Tray. Shift Tray Paper Empty
Sensor detects a paper empty condition on the Shift Tray.

•

Main Tray Paper Empty Board works when the 3rd Drawer is slid into the Cabinet (when
the Main Tray is at the lower limit position). 3rd Dra wer paper Empty Sensor works when
the Main Tray is at the upper limit position.

•

When a paper empty condition is detected on the Main T ra y during a multi cop y cycle, the
paper stack on the Shift Tray, if available, is transferred to the Main Tray to continue the
copy operation.

•

If paper is not loaded on the Shift T r ay but paper of the same size and direction is loaded
at any other paper feed port when the Main T ray becomes empty, t hat paper port is auto­matically selected for the remaining copies.

•

If no paper of the same size and direction is available, the paper empty message is dis­played and the copy cycle stops.

7-10. Paper Level Detection (30 cpm Copier Only)

•

The amount of paper still available f or use , or the paper level, of the 3rd Drawer is
detected by the Elevator Motor Pulse Sensor located inside the drive base assy and a
pulse disk.

•

The pulse disk is mounted on the shaft of the i ntermediary gear that transmits drive from
the Main Tray Elevator Motor. The speed of the pulse disk varies with different paper lev­els and the number of pulses detected by the Elevator Motor Pulse Sensor is used to
determine the paper level.

•

Counting of the number of pulses is started when the Main Tray Elevator Motor is ener­gized and continues until the output from the 3rd Drawer Paper Lift-Up Sensor goes
LOW. The total number of pulses is translated into the amount of paper which is shown
on the Touch Panel as a graphic marker in units of paper ass shown below. A paper level
of 500 sheets or more is shown, however, when the Shift Tray Paper Empty Sensor is
activated (paper present).

•

As the paper is consumed and each time the Main Tray is raised (the Main Tray Elevator
Motor is energized), the Elev ator Motor Pulse Sensor detects pulses and that pulse count
is accumulated. When the count reaches the number of sheets of paper in the units
shown below , the corresponding segment or segments of the paper level indicator on the
Touch Panel go out.

The Drawer is pushed out approx. 70 mm by the force of the Drawer Spring.

Pull out the Drawer.

2. When Drawer is Slid in
When the Drawer is slid into the cabinet, it is automatically locked by the locking pawl.
At the same time, 3rd Drawer Set Detecting Plate A blocks 3rd Drawer Set Sensor.
