GENERAL PRECAUTIONS REGARDING THE INSTALLATION
AND SERVICE FOR e-STUDIO3511/4511
The installation and service should be done by a qualified service technician.
1. Transportation/Installation
• When transporting/installing the equipment, employ four persons and be sure to use the positions
as indicated below.
The equipment is quite heavy and weighs approximately 112kg (246 lb.), therefore pay full attention
when handling it.
• Be sure not to hold the movable parts or units (e.g. the control panel, ADU or RADF) when
transporting the equipment.
• Be sure to use a dedicated outlet with AC 110/13.2A, 115V or 127V/12A, 220V-240V or 240V/
8A) for its power source.
• The equipment must be grounded for safety.
Never ground it to a gas pipe or a water pipe.
• Select a suitable place for installation.
Avoid excessive heat, high humidity, dust, vibration and direct sunlight.
• Also provide proper ventilation as the equipment emits a slight amount of ozone.
• To insure adequate working space for the copying operation, keep a minimum clearance of
80 cm (32”) on the left, 80 cm (32”) on the right and 10 cm (4”) in the rear.
• The socket-outlet shall be installed near the equipment and shall be easily accessible.
2. Service of Machines
• Basically, be sure to turn the main switch off and unplug the power cord during service.
• Be sure not to touch high-temperature sections such as the exposure lamp, the fuser unit, the
damp heater and their periphery.
• Be sure not to touch high-voltage sections such as the chargers, transfer belt, 2nd transfer roller,
developer, IH control circuit, high-voltage transformer, exposure lamp control inverter, inverter
for the LCD backlight and power supply unit. Especially, the board of these components should
not be touched since the electric charge may remain in the capacitors, etc. on them even after
the power is turned OFF.
• Be sure not to touch rotating/operating sections such as gears, belts, pulleys, fan, etc.
• Be careful when removing the covers since there might be the parts with very sharp edges
underneath.
• When servicing the machines with the main switch turned on, be sure not to touch live sections
and rotating/operating sections. Avoid exposure to laser radiation.
• Use suitable measuring instruments and tools.
• Avoid exposure to laser radiation during servicing.
- Avoid direct exposure to the beam.
- Do not insert tools, parts, etc. that are reflective into the path of the laser beam.
- Remove all watches, rings, bracelets, etc. that are reflective.
• Unplug the power cable and clean the area around the prongs of the plug once a year or more.
A fire may occur when dust lies on this area.

3. Main Service Parts for Safety
• The breaker, door switch, fuse, thermostat, thermofuse, thermistor, etc. are particularly important
for safety. Be sure to handle/install them properly. If these parts are shorted circuit and/or made
their functions out, they may burn down, for instance, and may result in fatal accidents. Do not
allow a short circuit to occur. Do not use the parts not recommended by Toshiba TEC Corporation.
4. Cautionary Labels
• During servicing, be sure to check the rating plate and the cautionary labels such as “Unplug the
power cord during service”, “Hot area”, “Laser warning label” etc. to see if there is any dirt on
their surface and whether they are properly stuck to the equipment.
5. Disposition of Consumable Parts, Packing Materials, Used batteries and RAM-ICs
• Regarding the recovery and disposal of the equipment, supplies, consumable parts, packing
materials, used batteries and RAM-ICs including lithium batteries, follow the relevant local
regulations or rules.
6. When parts are disassembled, reassembly is basically the reverse of disassembly unless
otherwise noted in this manual or other related documents. Be careful not to reassemble
small parts such as screws, washers, pins, E-rings, star washers in the wrong places.
7. Basically, the machine should not be operated with any parts removed or disassembled.
8. Precautions Against Static Electricity
• The PC board must be stored in an anti-electrostatic bag and handled carefully using a wristband,
because the ICs on it may become damaged due to static electricity.
Caution: Before using the wristband, pull out the power cord plug of the equipment and
make sure that there are no uninsulated charged objects in the vicinity.
Caution : Dispose of used batteries and RAM-ICs including lithium batteries
according to this manual.
Attention : Se débarrasser de batteries et RAM-ICs usés y compris les batteries
en lithium selon ce manuel.
Vorsicht : Entsorgung des gebrauchten Batterien und RAM-ICs (inklusive
der Lithium-Batterie) nach diesem Handbuch.

(b) Function of each board
CCD board:
This is the board to convert the reflected light by the original to electrical signals. It consists of the
CCD, A/D converter, etc. The CCD converts the reflected light by the original to three-color analog
signal; red, green, blue, and the A/D converter converts each analog signal to digital.
SLG board:
This is the board to mainly control the scanning function (scanner unit) and consists of the ScannerCPU, ASIC, memory (Flash ROM, SRAM), etc. When scanning the original, the exposure lamp and
scan motor are started by the command from the Scanner-CPU. And the image processing is
performed for the image data sent from the CCD by each ASIC.
SDV board:
This is the board on which the driver for driving the scan motor is mounted. The scan motor is started
by the command from the Scanner-CPU.
INV board:
This is the board on which the lighting control circuit of the exposure lamp is mounted. The exposure
lamp lights by the command from the Scanner-CPU.
e-STUDIO3511/4511 OUTLINE OF THE MACHINE 2 - 22 November 2003 © TOSHIBA TEC
Page 41
DSP board:
This is the board to mainly control the control panel. The Panel processing CPU detecting the input
from each button and touch panel, and the lighting control circuit for the backlight of the LCD are
mounted. And it relays the control signal of the control panel from the SYS board to the LCD and
KEY board.
KEY board:
This is the board on which each button switch and each LED on the control panel are mounted.
LDR board:
This is the board on which the laser diode and the ASIC are mounted. The laser is emitted based on
the output image data signal from the ASIC on the LGC board.
SNS board:
This is the board on which the light sensor for detecting the radiating position of the laser is mounted.
It outputs the H-sync signal to the PWM (Pulse Width Modulator) on the LGC board.
SFB board:
This is the board on which the circuit pattern is printed. It detects the position of the slide guide of the
bypass unit.
2
CCL board:
This is the board on which the driver for driving the charger cleaner motor is mounted.
ADU board:
This is the board to relay each signal between the ASIC on the LGC board and the electric parts
(motor, sensor, clutch) in the ADU.
IH board:
This is the board to generate the electric power for driving the IH coil of the fuser unit from the AC
electric power input via the switching power supply. And then it is provided.
DRV board:
This is the board on which the driver for driving the revolver motor, exit motor, and each fan motor are
mounted.
SYS board:
This is the main board taking a leading part in all systems. It consists of the System-CPU, ASIC,
memory (DIMM, Flash ROM, SRAM, NVRAM), RTC (Real Time Clock IC) etc. The System-CPU
controls each ASIC to perform the control of the image processing, image memory (page memory,
main memory, HDD), external interface (RS-232C, IEEE-1284, USB, PCI), NIC, and FAX. And based
on the input data from the control panel, System-CPU communicates with Scanner-CPU on the SLG
board and Engine-CPU on the LGC board, and then issues an operation command to the scanner
and printer engine section.

Page 42
LGC board:
This is the board to mainly control the print function (printer engine). It consists of the Engine-CPU,
2
ASIC, memory (Flash ROM, SRAM, NVRAM), etc. The Engine-CPU controls each ASIC to drive I/O
(electrical parts) of each section in the system. It leads to the operation of the laser unit, revolver,
developer unit, drum, transfer belt, drawers, bypass unit, ADU, etc. And then the print is made.
NIC board:
This is the interface board to connect this equipment to the LAN environment (10BASE-T, 100BASETX) to communicate with PCs, etc.
FIL board:
This is the board to cut off the noise of AC power from outside, and supply the driving AC power to
the damp heater for condensation prevention of each section (scanner and drum).
FUS board:
This is the board to provide the AC electric power for driving to the damp heater for preventing of the
condensation of each section (scanner and drum).
HVT:
This is the board to generate the DC high voltage from +24V to provide the bias to the section of the
main charger, developer, and transfer.
PS-ACC:
This is the unit to generate each DC voltage, which is used in the equipment, from external AC
electric power input. And then it is provided to each electric part.

3.3 Details of Copying Process
(1) Photoconductive drum
The photoconductive drum consists of two layers.
The outer layer is a photoconductive layer made of
an organic photoconductive carrier (OPC), and the
inner layer is an aluminum conductive base in a
cylindrical form.
The photoconductive carrier has a special property:
when it is exposed to light, the electrical resistance
it possesses increases or decreases with the
strength of the light.
Example:
· Strong incident light→
Decreases resistance (works as a conductor.)
· Weak incident light→
Increases resistance (works as an insulator.)

[Formation of electrostatic latent images]
In the processes of charging, data reading, data
writing, and discharging described below, the areas
on the drum corresponding to colored areas on the
original are deprived of negative charge, while the
areas on the drum corresponding to white areas
retain the negative charge. Thus it forms a negative
charge image on the drum surface.
As this negative charge image on the drum is not
visible to the human eye, it is called an “electrostatic
latent image.”
(2) Charging
Charging is a process to apply charge evenly to
the drum surface.
The charger wire produces negative corona
discharge, which is controlled by the grid so that

by the grid potential and is controlled to a fixed value
by the grid control circuit.

The CCD for color processing has RGB filters
provided over its surface, which allow the CCD to
read the light amount in the respective ranges of
wavelength. The image data corresponding to the
respective RGB colors is then transmitted to the
image processing section.

(5) Development
Development is a process of making the
electrostatic latent images visible to the eye
(visible image).
Developer material is supplied to the
photoconductive drum surface by means of a
magnetic roller, allowing the toner in the
developer material to adhere to the areas on the
drum surface where the potential is lower than
the developer bias which is applied to the
magnetic roller (reverse development).

• About developer material
The developer material is comprised of a mixture
of toner and carrier. The toner is charged to a
Coloring agent
(5-10%)
negative polarity and the carrier to a positive

polarity, due to the friction with each other
caused by mixing.
Resin (90-95%)
[Toner]
Toner : Mainly consists of resin and coloring.

Ferrite
Carrier: Consists of ferrite, and over its surface
resin coating to provide consistent frictional
electrification.

Note:
If the developer material is used for a long period

of time (beyond its normal life span), toner will
become caked onto the carrier.
→
The performance of the carrier is lowered.
Result: 1. Image density is lowered.
2. Toner scattering occurs.
3. Background fogging occurs.
Solution: Replace the developer material.
• Magnetic roller
- Magnetic brush development technique -
Inside magnetic rollers, the south and north poles
are arranged as shown in the right figure. The
developer material forms a brush-like fluff which
contacts the photoconductive drum surface.
→
This is caused by the lines of magnetic force
between the south and north poles.

(6) 1st transfer
• 1st transfer is a process of transcribing the
toner image (visible image) formed on the
photoconductive drum to the transfer belt. A
positive bias is applied to the transfer roller,
causing the transfer belt to be positively
charged. This in turn helps to form an electric
field E between the transfer belt (positive) and
the photoconductive layer of the
photoconductive drum (grounded), thus making
the toner image transferred to the transfer belt.
In the copy process of this equipment, images
are transferred in the order of K→C→M→Y on
Transfer belt

the transfer belt.
(7) 2nd transfer
• An electrostatic attracting force occurs between
the polarized charge (negative) on the lower
surface of transfer belt and the belt itself (positive).
That makes the toner being absorbed from the
belt to the paper. Then an electric field is formed
between the 2nd transfer roller and the transfer
belt drive roller, which generates a paper
polarization and thus the toner is transferred from
the belt to the paper.

(9) Blade cleaning
While eliminating the (+) charge on the
photoconductive drum applied during the transfer
stage, the conductive blade recovers the toner
left on the drum at the same time.
• Elimination of transfer charge
With this OPC photoconductive drum, (+)
charge on their surface cannot be eliminated
optically. Therefore, (–) voltage is applied to the
conductive blade, which is pressed against the
drum, to eliminate the (+) charge applied at the
transfer process.

(10) Discharging process
Discharging is a process of eliminating the (–) charge
remaining on the photoconductive drum before the next
charging process.
If the charge remaining on the photoconductive drum
is not eliminated, the following phenomenon would
occur:
(–) charge remaining on the photoconductive drum
surface causes uneven application of the charge for
the next copying.
→
The next copy obtains a double image. (The preceding
image remains.)
To prevent this :

is flooded with light by the discharge LED array.
