1. Precautions

1.3 ESD Precautions

Certain semiconductor devices can be easily damaged by static electricity. Such components are commonly
called “Electrostatically Sensitive (ES) Devices” or ESDs. Examples of typical ESDs are: integrated circuits,
some eld effect transistors, and semiconductor “chip” components.
The techniques outlined below should be followed to help reduce the incidence of component damage
caused by static electricity.

Caution >>Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

1. Immediately before handling a semiconductor component or semiconductor-equipped assembly, drain

off any electrostatic charge on your body by touching a known earth ground. Alternatively, employ a
commercially available wrist strap device, which should be removed for your personal safety reasons prior
to applying power to the unit under test.

2. After removing an electrical assembly equipped with ESDs, place the assembly on a conductive surface,

such as aluminum or copper foil, or conductive foam, to prevent electrostatic charge buildup in the vicinity
of the assembly.

3. Use only a grounded tip soldering iron to solder or desolder ESDs.

4. Use only an “anti-static” solder removal device. Some solder removal devices not classi ed as “anti-static”

can generate electrical charges suf cient to damage ESDs.

5. Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges suf cient to

damage ESDs.

6. Do not remove a replacement ESD from its protective packaging until immediately before installing it. Most

replacement ESDs are packaged with all leads shorted together by conductive foam, aluminum foil, or a
comparable conductive material.

7. Immediately before removing the protective shorting material from the leads of a replacement ESD, touch

the protective material to the chassis or circuit assembly into which the device will be installed.

8. Maintain continuous electrical contact between the ESD and the assembly into which it will be installed,

until completely plugged or soldered into the circuit.

9. Minimize bodily motions when handling unpackaged replacement ESDs. Normal motions, such as

the brushing together of clothing fabric and lifting one’s foot from a carpeted oor, can generate static
electricity suf cient to damage an ESD.

OPC Drum

OPC Drum

Transfer Roller

Transfer Roller

This mono printing system includes the LSU with a laser beams, a toner cartridge and transfer roller.
This machine uses single toner cartridge and dual laser beams for mono printing. The toner cartridge

consists of Drum unit and Development unit. The Drum unit has an OPC drum, cleaning blade.
The OPC drum is charged with a negative voltage by the scorotron and is exposed by the light from the LSU

(Laser Scanning unit). The light produced by a laser creates a latent image by discharging on the surface
of the OPC drum. The negatively charged toners are attracted to the latent image due to and electric filed.
The toners(real image) on the OPC drum are moved to the transfer media by the positive bias applied to the
transfer roller.

1. Charging the OPC drum: The scorotron gives the drum negative charges.

2. Laser exposure: Light produced by a laser diode irradiates the charged OPC through the lens and mirrors.

3. Development: This machine uses a dual-component development system . The magnetic roller carries negatively

charged toner to the latent image on the drum surface.

4. Transfer: The transfer rollers opposite the OPC drums transfer toner from the drums to the transfer media (e.g.
paper, OHP film, etc).

5. Cleaning for OPC drum: The cleaning blade removes remaining toners on the drum surface after image transfer

to the paper.

2.2.4.4 LSU (Laser Scanning Unit)

It is the core part of the LBP which switches from the video data received to the controller to the electrostatic
latent image on the OPC drum by controlling laser beam, exposing OPC drum, and turning principle of
polygon mirror. The OPC drum is turned with the paper feeding speed. The /HSYNC signal is created when
the laser beam from LSU reaches the end of the polygon mirror, and the signal is sent to the controller.
The controller detects the /HSYNC signal to adjust the vertical line of the image on paper. In other words,
after the /HSYNC signal is detected, the image data is sent to the LSU to adjust the left margin on paper.
The one side of the polygon mirror is one line for scanning.

2.2.6 Engine F/W Control Algorithm

2.2.6.1 Feeding

If feeding from a cassette, the drive of the pickup roller is controlled by controlling the solenoid. The on/off
of the solenoid is controlled by controlling the general output port or the external output port. While paper
moves, occurrence of Jam is judged as below.

ITEM Description

- After picking up, paper cannot be entered because paper is not fed.

- After picking up, paper entered but it cannot reach to the feed sensor in certain time

JAM 0

JAM 1

due to slip, etc.

- After picking up, if the feed sensor is not on, re-pick up. After re-picking up, if the feed
sensor is not on after predetermined period of time, it is JAM 0.

- After the leading edge of the paper passes the feed sensor, the trailing edge of the
paper cannot pass the feed sensor after predetermined period of time.

- After the leading edge of the paper passes the feed sensor, the paper cannot reach
the exit sensor after predetermined period of time.

*The paper exists between the feed sensor and the exit sensor.

JAM 2

- After the trailing edge of the paper passes the feed sensor, the paper cannot pass the

exit sensor predetermined period of time.

2.2.6.2 Transfer

The charging voltage, developing voltage and the transfer voltage are controlled by PWM (Pulse Width
Modulation). The each output voltage is changeable due to the PWM duty. The transfer voltage admitted
when the paper passes the transfer roller is decided by environment conditions. The resistance value of the
transfer roller is changed due to the surrounding environment or the environment of the set, and the voltage
value, which changes due to the environments, is changed through AD converter. The voltage value for
impressing to the transfer roller is decided by the changed value.

2.2.6.3 Fusing

The temperature change of the heat roller’s surface is changed to the resistance value through the use of a
thermistor.
The Main Bd uses the resistance value of the Thermistor and converts it to a voltage value through the use
of an AD converter, the temperature is decided based on the voltage value read. The AC power is controlled
by comparing the target temperature to the value from the thermistor. If the value from the thermistor is out of
controlling range while controlling the fusing, the error stated in the below table occurs.

• Open Heat Error

When the engine operates the warm-up process, if the temperature of the fixing unit is not higher than a
specified temperature, the engine defines Open Heat Error. When this error is detected, the engine stops
all functions and keeps the error state. Also, the engine informs the error status of the main system, so it can
take appropriate action; and then the error message is displayed at LCD window or LED informing the error
status of the user.

• Low Heat Error

When the engine is at stand-by, printing or warm-up mode, if the temperature of the fixing unit is lower than
the specified temperature at each state and the lower temperature state is maintained during the specified
time, the engine defines Low Heat Error. When this error is detected, the engine stops all functions and
keeps it at the error state. Also, the engine informs the error status of the main system, so it can take
appropriate action; and then the error message is displayed at LCD window or LED informing the error status
of the user.

• Over Heat Error

For overall engine state, if the temperature of the fixing unit is higher than the specified temperature and the
temperature state is detected for a specific duration, then the engine defines Over Heat Error. When this
error is detected, the engine stops all functions and keeps it at the error state. Also, the engine informs the
error status of the main system, so it can take appropriate action; and then the error message is displayed at
LCD window or LED informing the error status of the user.

2.2.6.4 LSU

LSU receives the image data from PVC or HPVC and make the latent image on OPC surface.
It uses the single beam, LD. The errors related to LSU are as follows:

• By Lready

When the printing is started, the engine drives the polygon motor of LSU. After the specified time is elapsed,
if the motor is not in a ready status, the engine detects the error that the polygon motor is not in a ready
status. If this error happens, the engine stops all functions and keeps it at the error state. Also, the engine
informs the error status of the main system and the error message is displayed at LCD window to inform the
error status of the user.

• By Hsync

When the polygon motor is ready, the LSU sends out the signal called Hsync and used to synchronize with
each image line. So, if the engine does not detect consecutively the signal for a fixed time, it defines the
Hsync Error. If this error happens, the engine stops all functions and keeps it at the error state. Also, the
engine informs the error status of the main system and then the error message is displayed at LCD window
to inform the error status of the user. LSU Error Recovery: If the LReady or Hsync error happens, the paper
is exited before the error code is initiated. The engine mode is changed to recovery mode and the engine
informs the main system of the engine mode. And the engine checks the LSU error. If the error doesn’t
happen, the printing job.

4. Web-based-Application that offers the same functions as Stand-alone Application and RDC(Remote
Diagnosis Control) in Web environment.

Firmware is made up of

1. Application (Emulation) that is a interpreter translate data received from Host to a printing language

(PCL, PS, GDI, etc.) to be able to make the user to take same output as originally one what composed in
Host.

2. Kernel that control and management the whole procedure include of Control flow and Printing Job before
transfer to Engine system.

Firmware Side is made up of :

1. Network Interface Application is that relay the communication between Host and kernel using various
network protocol.

2. Kernel is that manages the flow control of emulation procedure, receiving data from Host or Network
application and printing with engine & rendering job,

3. Emulation is that interprets the various output data from selected emulation,

4. Engine is that prints rendered bit-map data to paper with required size and type by Kernel.

And then, for Job Spooling function for Multi-User, Multi-Printing that is occurred in Network printing and
various additional printing functions, this Kernel uses max. 10 Queuing systems in a memory.

In Printing, the two procedures are :

(1) Case of using USB Port

- After user start to print the wanted document to PCL string or compressed GDI bit-map data, Driver

translate the all graphic data of it and send data to host spooler. And then the spooler sends the data
stream to the printer via USB port.

- Kernel receives this data from Host, and then select emulation fit to data and start selected one. After
emulation job end, Kernel sends the output bit-map data to Engine using Printer Video Controller (by
clock type for LSU).

- Engine print the received data to required paper with the sequential developing process.

(2) Case of using Network Interface Application

- After user start to print the wanted document to PCL string or compressed GDI bit-map data, Driver
translate the all graphic data of it and send data to host spooler.

- If so, Port monitor managing network port receives data from spooler and sends a data stream to the
Network Interface Application.

- Network interface card receives it and send to Kernel part.

- Kernel receives this data from Host, and then select emulation fit to data and start selected one. After
emulation job end, Kernel sends the output bit-map data to Engine using Printer Video Controller (by
clock type for LSU).

- Engine print the received data to required paper with the sequential developing process.

3.1 General Precautions on Disassembly

When you disassemble and reassemble
components, you must use extreme caution. The
close proximity of cables to moving parts makes
proper routing a must.
If components are removed, any cables disturbed
by the procedure must be restored as close as
possible to their original positions. Before removing
any component from the machine, note the cable
routing that will be affected.

Whenever servicing the machine, you
must perform as follows:

1. Check to verify that documents are not stored in
memory.

2. Be sure to remove the toner cartridge before you
disassemble parts.

3. Unplug the power cord.

4. Use a clean at surface.

5. Replace only with authorized components.

Releasing Plastic Latches

Many of the parts are held in place with plastic
latches. The latches break easily; release them
carefully.
To remove such parts, press the hook end of the
latch away carefully from the part to which it is
latched.

6. Do not force plastic-material components.

7. Make sure all components are in their proper
position.
