•
When a service job needs to be performed in the laser beam path, such as when working
around the Print Head Unit and PC Drum, be sure first to turn the copier OFF.
•
If the job requires that the power cord be left plugged in, observe the follo wing precautions
1. Take off your watch, ring, and any other reflective object and wear laser protective goggles.
2. At the job site, select a place that is as far as possible away from the users and that is
enclosed by walls.
3. Do not bring a highly reflective tool into the laser beam path during the service job.

5 CPU OVERRUN MONITOR FUNCTION
•
CPU Overrun Monitor Function (Watchdog Function)
The watchdog function is a self-monitoring function that determines whether any of the
CPUs mounted on the control board overrun.
•
If this function detects that a CPU overruns, the copier automatically resets the CPU,
thereby restarting the logic circuit and mechanism.
•
Even if a copier CPU operates erratically due to electrical noise, therefore, the copier is
able to recover from the f aulty condition so that the number of visits made by the Tech.
Rep. for CPU overrun can be minimized.
•
Processing performed during watchdog function:
If a faulty condition is detected, the copier resets the CPU and performs a restart
sequence. Since this sequence of operations is performed even during a copy cycle, the
copier detects a sheet or sheets of paper left inside it as a misfeed while it is being
restarted.

7-2. Identification and Life of I/C
•
When the Start key is pressed or the Side Cover is opened and closed, the copier determines whether the I/C is new or one which has been used previously.
•
The copier monitors the I/C life by storing in memory the period of time during which the
PC Drum has turned. The data is cleared when a new I/C is installed in the copier.

8 PC DRUM
•
The PC Drum used in this copier is the organic photoconductor (OPC) type.
The drum consists of an aluminum base coated with a charge generation layer and a
charge transport layer.
Handling Precautions
Prolonged exposure to light can cause the photoconductor surface of the drum to suffer
light fatigue, resulting in a loss of photosensitivity. If the I/C is removed from the copier, it
should be wrapped in a soft, clean, opaque cloth or other protective cover ing to prevent
exposure to light.

Grounding of the PC Drum
The PC Drum ground point is located inside and at the front end of the I/C as viewed
from the front of the copier and in constant contact with the Drum Holding Shaft. When
the I/C is installed in the copier, the Drum Holding Shaft contacts the ground point. This
provides for assured grounding of the PC Drum through the ground plate in the rear to
the frame of the copier.

9 DRUM CHARGING
•
A scorotron charger system generates a negative DC corona discharge onto the PC
Drum surface. The grid mesh ensures uniform charging.
•
The grid voltage (Vg) applied to the grid mesh is controlled by the constant voltage circuitry within the High Voltage Unit. It is varied through image stabilization control.
•
To restrict ozone production, the copier uses a PC Drum Charge Corona with a comb
electrode.

10 ERASE LAMP
•
Any potential remaining on the surface of the PC Drum is neutralized by both light from
the Erase Lamp and a DC negative voltage applied by the Charge Neutralizing Sheet.
•
The Charge Neutralizing Sheet applies a negative charge on the surface of t he PC Drum
which is positively charged by the Image Transfer Roller. A voltage of -820V is applied to
the Charge Neutralizing Sheet from the High V oltage Unit. The Erase Lamp then illuminates the surface of the PC Drum to further neutralize it.
•
The Erase Lamp consists of ten tungsten lamps.

1. Photoelectric Conversion (CCD Sensor)
2. HGB Board
Transmitted over an optical cable.
3. MFB Board
4. PH (Laser Emission)
1. Photoelectric Conversion (CCD Sensor)
•
Light reflected off the original is received through mirrors and lens by the CCD Sensor
which, in turn, outputs the corresponding data to the HGB Board.
2. HGB Board
•
After converting the data received from the CCD to an analog signal, the board converts
it to 8-bit image data (A/D conversion). It further makes various corrections and outputs
the resultant image data to the MFB Board over an optical cable.
3. MFB Board
•
This board compresses the image data received from the HGB Board, stores it, and
uncompresses it.
•
The image memory has a standard capacity of 16MB and can be expanded up to 64MB
(optional).
4. PH

11-5. Scanner and 2nd/3rd Mirrors Carriage Moving Mechanism
<Scanner>
•
During a scan, the Scanner projects an even amount of light from the Exposure Lamp
onto the entire surface of the original. The light is reflected from the original to the 1st
Mirror of the scanner and then to the 2nd and 3rd Mirrors.
•
The Scanner is driven by the Scanner Motor and front and rear Scanner Drive Cables.
•
Scanner speed is determined by the set zoom ratio in reference to the full size mode.
•
The Scanner is at home position when Scanner Home Position Sensor 1 is block ed. This
position serves as the reference for the scan motion.
•
Scanner Home Position Sensor 2 determines the home position of the Scanner when
AF-7 is used.
<2nd/3rd Mirrors Carriage>
•
The 2nd and 3rd Mirrors are mounted to their holder at right angles to each other. They
direct the light reflected off the 1st Mirror through the lens to the CCD.
•
The 2nd/3rd Mirrors Carriage is also moved by the Scanner Drive Cables and pulleys
driven by the Scanner Motor . It trav els at a speed half that of the Scanner, thereby keeping constant the optical path length between the Original Glass and lens.

•
The signal output from the Master Board triggers the firing of the laser. The laser beam
travels to the Polygon Mirror, lens, and SOS Mirror to eventually hit the SOS Sensor,
which generates an SOS signal.
•
The SOS signal determines the laser emission timing for each line in the main scanning
direction.

13 DEVELOPING UNIT
•
The Toner Conveying Rollers mix the toner and carrier particles together and carry the
toner/carrier mixture up to the Sleeve/Magnet Roller . The magnetic brush formed on the
surface of the roller allows the toner to come into contact with the charges on the surface
of the PC Drum, thus forming an electrostatic latent image.

13-1. Sleeve/Magnet Roller
•
This copier employs the MT-HG system with a Sleeve/Magnet Roller ha ving the f ollo wi ng
magnetic characteristics.
•
Turning of the sleeve surrounding the Magnet Roller ensures that fresh developer from
the Developer Mixing Chamber is always being conveyed to the point of development
with respect to the PC Drum.
N1 : The point of development with the maximum magnetic flux density which
ensures that the carrier is firmly held onto the Sleeve Roller when toner is
attracted to the latent image.
S1, N2 : The magnetic flux density between these two poles is made low to ensure that
the developer remaining on the surface of the Sleeve Roller is smoothly recycled. They also prevent developer from scattering.
N3 : The developer brush is formed by this pole and its height is moderated before
the brush is regulated by the Doctor Blade.
S2a : This pole ensures that the developer is conveyed to the point of development
over the wide interval between N3 and N1.
S2b : If developer is compacted and clogs at the Doctor Blade and, as a result, part
of the surface of the Sleeve/Magnet Roller is not covered with developer, the
nearby developer around this pole with a weak magnetic force goes to those
uncovered areas. This helps prevent white lines from occurring on the copy.

13-2. Developing Bias
•
The amount of toner attracted onto the surface of the PC Drum is controlled by varying
the developing bias voltage.
•
As the PC Drum deteriorates and its photoconductive layer begins to wear, it becomes
more sensitive to the increase in the amount of toner. As a countermeasure against this
problem, the dev eloping bias v oltage is automatically swi tched according to the PC Drum
temperature, thereby stabilizing the image quality level.

13-3. ATDC Sensor
•
The ATDC Sensor automatic adjustment is made when a new I/C is installed in the
copier. Toner replenishing control is thereafter controlled as detailed in the following.
1. ATDC Sensor Automatic Adjustment
•
The ATDC Sensor is automatically adjusted when a new I/C is loaded in the copier. During this sequence, the copier reads the sensor output value and sets it as the reference.
This reference value is stored in memory and used until the I/C reaches its service life.
2. Toner Replenishing Control
•
While the I/C Motor is turning, the ATDC Sensor samples T/C and, according to the readings, the copier provides the following controls.
T/C Ratio (%) Sampling Data (V) Control Details
More than 19 Less than 1.41 Defective ATDC Sensor

✽
Toner replenishment represents the operation of the Sub Hopper Toner Replenishing
Motor.
3. Toner Empty Control (T/C Recovery Mode)
•
When the control is passed onto the T/C recovery mode, the Sub Hopper Toner Replenishing Motor is energized to replenish the supply of toner into the Developing Unit and, if
T/C is recovered to a lev el of 14% or higher (2.32V or less) within 150 sec., it resets the
toner-empty condition.
Toner replenished for 54 msec. at intervals of
approx. 1 sec.

•
A toner-empty condition in the Sub Hopper is detected by the Magnet Lever that moves
up and down as the Sub Hopper Toner Agitating Lev er turns and actuates and deactuates the Sub Hopper Toner Empty Switch.
•
While the amount of toner in the Sub Hopper is more than the predetermined amount,
the Magnet Lever rests on the toner, keeping the Sub Hopper Toner Empty Switch deactuated even when the Sub Hopper Toner Agitating Lever turns. As toner is consumed,
the Magnet Lever lowers to eventually actuate the Sub Hopper Toner Empty Switch, at
which timing the copier detects a toner-empty condition in the Sub Hopper.

•
When a toner-empty condition in the Sub Hopper is detected, the Main Hopper Toner
Replenishing Motor is energized to turn the Toner Bottle, thereby supplying toner from
the Main Hopper to the Sub Hopper.
•
The Toner Bottle Home Position Sensor mounted on the coupling ensures that the Toner
Supply Port in the Toner Bottle is positioned at the top whenever the bottle is stopped.
•
The Toner Bottle Cover Sensor detects whether the Toner Bottle Cover is open. If the
cover is open, the copier does not authorize the initiation of a new copy cycle. If the
cover is opened during a copy cycle, the copier interrupts the cycle.

1 PRECAUTIONS FOR HANDLING THE PWBs
1-1. Precautions for Transportation and Storage
•
Before transporting or storing the PWBs, put them in protective conductive cases or bags
so that they are not subjected to high t emperature and are not exposed to direct sunlight.
•
Protect the PWBs from any external force so that they are not bent or damaged.
•
Once the PWB has been removed from its conductive case or bag, never place it directly
on an object that is easily charged with static electricity (such as a carpet or plastic bag).
•
Do not touch the parts and printed patterns on the PWBs with bare hands.
1-2.
•
Whenever replacing the PWB, make sure that the power cord of the copier has been
unplugged.
•
When the power is on, the connectors should never be plugged in or unplugged.
•
Use care not to strap the pins of an IC with a metal tool.
•
When touching the PWB, wear a wrist strap and connect its cord to a securely grounded
place whenever possible. If you cannot wear a wrist strap, touch the metal part to discharge static electricity before touching the PWB.
