Failure to do so could cause the printer to tip or fall possibly causing personal injury or damaging the printer.

(5) Do not install the printer on a sloping or unstable surface. After installation, double check that the printer is stable.

Precautions


1.3 ESD PrecautionsCertain 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 field 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 classified as “anti-static”

can generate electrical charges sufficient to damage ESDs.5. Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges sufficient 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 floor, can generate static electricity sufficient to damage an ESD.

(c) Sensor Input Circuit

Paper Empty Sensing

The Paper empty sensor on the HVPS detects the state of paper empty and the state of paper width i.e. narrow paper width or not. If the paper width sensor fails to detect paper existence, the fact has two meanings: paper empty or narrow paper installed. When the printing job comes to CPU, CPU does operate the pickup action regardless of paper empty. If the paper comes through to feed sensor, CPU recognizes the usage of narrow paper, if not, CPU know the state of paper empty and displays the RED on the OPE PBA.

Regi Sensing

By the operation of an actuator on the frame, Regi Sensor (Photo interrupter) informs the existence of paper to CPU. CPU recognize papers in Manual Feeder and , feed paper from Manual Feeder if there is.

Paper Feeding/With Toner Cartridge Sensing

When paper passes the actuator (feed sensor part), it detects the signal of Photo interrupter, informs the paper feeding state to CPU, and then sprays the image data after certain time.If it doesn’t detect the feed sensor within 1sec. after paper is fed, paper Jam0 is occurred (LED will be display RED color). The fact whether the developer is inserted or not is detected by CRUM. After the developer is mounted, the sub- CRUM can read the information of toner cartridge from contact with CRUM involved in toner cartridge. If the information of toner cartridge is invalid, it will show invalid sign on a LED.

Paper Exit Sensing

It detects paper state whether paper gets out from the set with operation of exit sensor and actuator on the fuser assy. Paper detects the on/off time of exit sensor and the normal operation or jam information is informed to the CPU.The paper JAM2 is informed. (LED will be display RED color)

Cover Open Sensing

The Cover open sensor is located on the HVPS. After the front cover is opened, +24VS (DC fan, Solenoid, Main Motor, Polygon motor part of LSU and HVPS), which is supplied to the each unit, is cut off. In case, the red will be ON for informing the facts to user.

DC FAN / SOLENOID Driving

DC Fans and Clutches are driven by turning on TRs, which is controlled by CPU. The diode in the Fan and Clutch driving circuits protects TR driven from the noise pulse, which is occurred when the solenoid and fan are de- energized.

2.2.5.1 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

JAM 0

- After picking up, paper cannot be entered due to paper is not fed.- After picking up, paper entered but it cannot reach to the feed sensor in certain time 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 certain time, it is JAM 0. * It is a status that the leading edge of the paper doesn’t pass the feed sensor.- Even though the paper reaches to the feed sensor, the feed sensor doesn’t be ON. * It is a status that the leading edge of the paper already passes the feed sensor.

JAM 1

- After the leading edge of the paper passes the feed sensor, the trailing edge of the paper cannot pass the feed sensor after a certain time. (The feed sensor cannot be OFF)

- After the leading edge of the paper passes the feed sensor, the paper cannot reach the exit sensor after certain time. (The exit sensor cannot be ON)

* 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 after certain time.

2.2.5.2 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 recognition. 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.



2.2.5.3 Fusing

The temperature change of the heat roller’s surface is changed to the resistance value through the thermistor. By converting the voltage value, which impressed to the resistance, to the digital value through the AD converter, the temperature is decided. The AC power is controller 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 broken out, the engine stops all functions and keeps the error state. Also, the engine informs the error status of the main system. 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 broken out, 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 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 kept during the specified time, the engine defines Over Heat Error. When this error is broken out, 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 or LED to inform the error status of the user.

2.2.5.4 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 exits out beforehand. 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 will be proceeding.



2.2.6 S/W Descriptions

2.2.6.1 Overview

understand and transfers data to spooler,3. Stand-alone Application that offers the various printing application, PSU(Printer Settings Utility), Printer

Status Monitor, Network Management in Window system,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 of1. 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.



2.2.6.3 Data and Control Flow

Host Side is made up of

1. Driver that is Windows application software translate printed data to one of printer language and create spooler file.

2. Web-based Application that offer a various printer additional functions, management of printing job, printer administration, Status monitor to monitoring the printer status by real time in Web, independent environment on OS.

3. Stand-alone Application that is a similar Window software as same as above 2,4. Port Monitor that manages the network communication between spooler and Network Interface Card, or

various additional application and Network Interface Card,(this is, at first, make communication logical port, manage the data, transfer them from spooler to network port, and offer the result of printing).

. GDI(only SCX-4824FN) & PCL6 (PCL XL)



Firmware Side is made up of

1. Network Interface Card 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 card 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 use 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 Card - 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 Card. - 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.

The additional printing function are realized in

(1) Web environment(2) Window environment.

On addition, Kernel informs a status of printing status and printer status to user made printing job with the Status Monitor.
