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.

Illumination Mechanism
4.1.1 Overview
The Illumination Mechanism efficiently uses the light produced by the
Projection Lamp to supply the most suitable amount of light for the
projection of the Microfilm. This amount of light is determined by the size
of the Microfilm and by the magnification ratio of the Lens selected for use.
4.1.2 Projection Lamp (LA1)
A DC20V, 150W halogen Lamp is used as the light source for the reader
and printer functions.
The Projection Lamp is integrated with a Lamp Reflector which is a
polygon mirror to ensure even illuminance.
NOTE
1. Whenever the Projection Lamp Unit is removed, Make sure that the
Power Switch is turned OFF.
2. Never touch the Projection Lamp immediately after it is turned OFF:
be careful, it is extremely hot.
3. Do not touch with hand or dirty with grease the surfaces of the
Projection Lamp and Lamp Reflector.

4.1.3 Projection Lamp Voltage Control Circuit
The intensity of the light emitted by the Projection Lamp is adjusted to a
level optimum for the image density by controlling the voltage applied to
the Projection Lamp.
The exposure data optimum for film image density is determined through
auto exposure data sampling made during prescan.
This exposure data is output as a Projection Lamp clock from the Main
Control Board (PWB-BB) to the Projection Lamp Regulator (PU2).
The ON and OFF periods of the Projection Lamp clock extending 606
µsec. are varied to control the Lamp voltage. The longer the OFF time, the
higher the Lamp voltage.

4.1.4 Thermostat (TS1)
To avoid any of the troubles accompanying an excessive rise in the
temperature inside the machine caused by a failure of the Cooling Fan to
dissipate heat produced by the Projection Lamp, there is a Thermostat
installed at the back of the Projection Lamp.
When the ambient temperature of the Projection Lamp exceeds 122°C the
Heat-Sensitive Plate expands pushing up the Pusher Pin, which in turn
cuts off the current to the Projection Lamp Circuit.
The Circuit is reset by pushing the Reset Pin.

4.1.5 Condenser Lens
Overview
G
Not only must the amount of light projected onto the Screen or CCD
remain even despite changes in the microfilm or magnification ratio, but
also the light coming from the Projection Lamp must be efficiently
condensed. To accomplish this, the machine is equipped with two
Movable Condenser Lens: one convex and one concave.
G
Movable Condenser Lenses
The Brightness Shift Lever is moved manually according to the
magnification of the Projection Lens being used so that the Movable
Condenser Lenses are moved to the set position. The set position is color-
coded, TYPE 1 to 3, each defined by a corresponding magnification of the
Projection Lens.

4.1.6 Projection Lens
The Projection Lens enlarges the image of the Microfilm and projects it
onto the Screen or CCD.
Each Projection Lens comes in a unit. The Focus Ring and Zoom Ring of
the Unit are used to bring the image on the Screen into focus and enlarge
or reduce it, respectively.
The Prism Lens for image rotation is installed in the Prism Holder fixed to
the machine.
The Projection Lens Unit is slid into position in the Lens Holder of the
machine. To insert the Unit, raise the Prism Holder and, at the same time,
push it into position.
When a Projection Lens Unit is installed, the Brightness Shift Lever must
be moved as required according to each magnification.

Image Rotation
The Prism Unit is rotated to correct any tilt of the image microfilm projected
on the Screen.
4.2.1 Prism Rotation
The Auto Image Rotating Knob is linked to the Auto Image Rotating
Variable Resistor (VR1). Turning the Knob clockwise or counterclockwise
turns the Auto Image Rotating Motor (M5) whose drive is transmitted via
a belt to the Prism Gear, thus turning the Prism Unit.

Optical Section
4.3.1 Overview
The basic function of the Optical Section is to project an enlargement of
the image on the microfilm onto the Screen when in the Reader Mode and
onto the CCD when in the Scan Mode.
There is a unique light path formed in each of these modes.
The light path formed in the Reader Mode is called the Reader Path and
that formed in the Scan Mode is called the Scan Path.
Each light path is formed by two Reader Path Mirrors and three Scan path
Mirrors.

4.3.2 Reader Path
The Reader Path is established when the Power Switch is turned ON and
remains formed except during a scan movement.
The image on the microfilm is projected onto the entire area of the Screen
by means of the two Reader Path Mirrors.
The light path between the Projection Lamp and Screen measures
1,293mm.
4.3.3 Scan Path
When in the Scan mode, the 1st Scan Path Mirror moves to a position that
will block the Reader Path.
It then turns to direct the film image through the four Scan Path Mirrors
onto the CCD so that it can read the image data in the sub-scanning
direction.
The light path between the Projection Lamp and CCD measures
1,298mm.

4.3.4 Scan Table Drive Mechanism
The Reader Path is switched from the Printer Path, or vice versa, by
moving the Scan Table to the respective positions.
The Scan Table is driven from the Scan Table Drive Motor (M2). The
direction and speed of rotation of the Scan Table Drive Motor (M2) are
controlled by the outputs from pins 3, 4, 5 and 6 (øA, øB, øA, and øB) of
PJ5T on the Motor Drive Board (PWB-T).

4.3.5 Scan Mirror Motion Control
The motion of the Scan Mirror is controlled by the Scan Lever and Shaft
as the Shaft is driven by the Scanning Motor (M1).
The Scan Mirror scans the image of the microfilm at a speed 1/631.6 of
the Scanning Motor (M1).
Once the prescan motion is initiated, the leading edge of the image is
synchronized with that of the paper, and the completion of the scan motion
is detected, by the Scan Start Position Sensor (PC1) which are activated
and deactivated by the cutouts in the light blocking Lever.
Scan Mirror first makes a prescan motion for reading the data before
making the scan motion.

4.3.6 Mirror Scan Motor (M1) Control Circuit
Drive of the Scanning Motor (M1) is controlled by the signals which are
input to the Motor Driver Board (PWB-T) from the Main Control Board
(PWB-BB).
These signals determine the direction (forward or backward) and speed of
rotation of the Scanning Motor when the Scan Mirror makes a prescan
and scan motion.
These signals cause the Scanning Motor drive pulses to be output from
the pins (A, B, A, B) of the Motor Driver Board (PWB-T), which turns the
Scanning Motor (M1).

The image data read by the CCD goes through analog-to-digital
conversion before being output.
CCD
The CCD (Charge Coupled Device) reads the data
on the Film.

Shading correction
Shading Correction
If the CCD were to read the reflected light from an
original having a uniform density, the outputs along
the length of that CCD may vary individually due to
uneven light distribution along the length of the
Lamp and varying sensitivities of different CCD
chips. These variations are corrected through
shading correction.

Line memory
The pixel signals from the five CCD chips are
output serially in the order of CCD1, CCD2, CCD3,
CCD4, and CCD5.
The data read by the CCD is proportionate to the
intensity of the light that has passed through the
film. A conversion formula is used to convert the
data read by the CCD into the image density data
which has a characteristic linear to the film density.

Each scanner can be set to print marks (I or II) in the top left-hand
corner of the page, enabling easy identification of each scanner’s print job.
Scanner
Printer
4.9.2 Operation
When printing, the scanner occupies the printer. When the print is ended,
the scanner opens the printer.
The scanning begins when the start key to the other scanner is pushed.
And waited that the printer is opened while storing the image in the
memory in the scanner while printing.
Meanwhile, scanner is shown for the Multi-print display to blink, and not to
accept the next scanning.
If the print of the preceding other scanner ends, and the printer is opened,
the image stored in the memory as here occupies the printer is printed.
A job that is waiting to be printed can be cancelled by pressing the Clear/
Stop key on the scanner that sent the job.
(Push the Clear/Stop Key three times when you used the print reserve
function)
As a result, the print job is deleted from the memory and that scanner's
Multi-print Display stops blinking and stays lit.

Handling of P.W.Boards
5.2.1 Precautions regarding transportation and storage
1. During shipment or when in storage, new P.W.Board must not be
indiscriminately removed from their protective bags.
2. Do not store or place these P.W.Boards in a location exposed to direct
sunlight or in a location where they will be exposed to high
temperatures.
3. After removal from a machine, P.W.Board must be placed in their
respective conductive bag or wrapped in aluminum foil without fail.
Never wrap them in plastic, paper or any other material.
4. When removal from the conductive bag or case becomes absolutely
necessary, always place the Board removed on its conductive mat in
an area as free as possible from static electricity.
5. Do not touch the terminals of the ICs with your bare hands.
5.2.2 Precautions when replacing PWBs
1. Any Board should be replaced as an Assy.
2. When taking any Board out of its conductive bag or conductive case,
do not touch the terminals of the ICs or the printed pattern. Place it in
position by holding only the edge of the Board.
3. Connect the connectors to or disconnect them from any Board only
after having unplugged the Main Power Cord of the machine.
5.2.3 Precautions when checking PWBs
1. Avoid checking PWBs with testers; instead, use operating parts of the
machine, indicator lamps, and other means to evaluate operational
conditions.
2. Never permit shorts between IC terminals due to metal fittings, etc.
3. If it is necessary to touch elements on the PWB with your hand, make
sure your body is properly grounded.
