The following instructions are for your own personal safety, to avoid injury and so as not to damage the printer

(1)

Ensure the printer is installed on a level surface, capable of supporting its weight. Failure to do so could

cause the printer to tip or fall. The printer contains many rollers, gears and fans. Take great care to ensure that you do not catch your

(2)

ngers, hair or clothing in any of these rotating devices.

Do not place any small metal objects, containers of water, chemicals or other liquids close to the printer

(3)

which if spilled could get into the machine and cause damage or a shock or re hazard.

(4)

Do not install the machine in areas with high dust or moisture levels, beside on open window or close to a

humidier or heater. Damage could be caused to the printer in such areas.

(5) Do not place candles, burning cigarettes, etc on the printer, These could cause a re.

1.2.4 Assembly / Disassembly Precautions

Replace parts carefully, always use authorized parts. Take care to note the exact location of parts and also

cable routing before dismantling any part of the machine. Ensure all parts and cables are replaced correctly. Please carry out the following procedures before dismantling the printer or replacing any parts.

(1)

Check the contents of the machine memory and make a note of any user settings. These will be erased if

the mainboard or network card is replaced. (2) Ensure that power is disconnected before servicing or replacing any electrical parts. (3) Disconnect printer interface cables and power cables. (4)

Only use approved spare parts. Ensure that part number, product name, any voltage, current or

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.

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.

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.

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.

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.

4) Sensor Input Circuit

■ Paper Empty Sensing & Paper Width Sensor

When a printing job comes to the CPU, the CPU initializes the pickup action regardless of the state of the sensor. If paper is then detected by the Feed Sensor, the paper will then be recognized as e.g. invoice paper even though the Paper Empty Sensor was on. If no paper is detected by the Feed Sensor, then the CPU will recognize that a “Paper Empty” condition exists and displays the RED warning light on the OPE PBA. When a printing job comes to the CPU, the CPU initializes the pickup action regardless of the state of the sensor. If paper is then detected by the Feed Sensor, the paper will then be recognized as e.g. invoice paper even though the Paper Empty Sensor was on. If no paper is detected by the Feed Sensor, then the CPU will recognize that a “Paper Empty” condition exists and displays the RED warning light on the OPE PBA.

■ Regi Sensing

The registration sensor (Regi Sensor, a photo interrupter) informs the CPU that paper is registered at the registration rollers, and waiting for proper leadedge schronization with the image on the drum.

■ Paper Feeding/With Toner Cartridge Sensing

When the leadedge of the paper is detected by the Feed Sensor (photo interrupter), it begins the development process of the drum after a predetermined time. The toner cartridge detection is monitored by the CRUM sensors. If all of the CRUM sensors are off, the CPU knows the cartridge is not in the machine, and takes appropriate action by turning on the out of toner light. If the CRUM sensors do not detect that the correct cartridge is inserted, the CPU will display the toner cartridge is invalid, it will show invalid sign on a LED.

■ Paper Exit Sensing

The Paper Exit Sensor is mounted on the Fuser Unit exit side, and is used to ensure that paper has indeed exited the machine. If the on/off time of exit sensor is abnormal, then a JAM2 is informed. The LED on the display will turn on a RED warning color.

■ Cover Open Sensing

The Cover Open Sensor is located on the HVPS. When the front cover is opened, all +24VS is shut off. Then the customer will be notied on the display that the door is open [“door open”] and the red will turn on.

■ DC FAN / SOLENOID Driving

DC Fans and Clutches are driven by turning on noise when these driver components de-energize. which is controlled by CPU. The diode in the Fan and Clutch driving circuits protects TR driven from noise when these driver components de-energize.

■ Motor Driving

2.2.5.1 Feeding

If feeding from a cassette, the drive to the pickup roller is controlled by a solenoid. The on/off time the solenoid is controlled by Main PBA. The Paper Jam protocols are as follows:

Item Description

JAM 0

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

- After picking up, paper does not reach the Feed Sensor in after a predetermined time due to paper slippage, etc.

- If the Feed Sensor does not detect paper after a predetermined time following the initialization of another take-up retry.

* 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

- The trailing edge of the paper must clear the Feed Sensor after predetermined time. (The feed sensor cannot be OFF)

- The leading edge of the paper must detect the Exit Sensor within a predetermined after leaving the Feed Sensor. (The exit sensor cannot be ON)

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

JAM 2 - The trailing edge of the paper must clear the Exit Sensor after predetermined time.

2.2.5.2 Transfer

The charging, developing and the transfer voltages are controlled by PWM (Pulse Width Modulation). Each output voltage may change 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 through AD converter. The voltage value for impressing to the transfer roller is decided by this value change.

2.2.5.3 Fusing

The temperature change of the heat roller’s surface is changed to the resistance value through the thermistor. The Heat Roller temperate (warmup) is measured by converting the resistance of the thermistor to a measurable DC voltage value. The AD converter changes it to a digital value so it knows when it has reach its proper fusing temperature. The AC power to the fuser lamp is controller by comparing the target temperature to the value from the thermistor. If the value from the thermistor is out of controlling range an error will occur and power disabled. The table below lists the types of Fuser Errors that can occur:

• Open Heat Error

During warmup, if the Fuser Unit does not reach its proper operating temperature within a predetermined time an “Open Heat Error will occur. An error message will be displayed on the Control Panel alerting the customer. The engine stops all functions and keeps it at the error state until the issue is resoled by a qualied technician.

• Low Heat Error

After initial warmup had been achieved, if the Fuser Unit at any time does not reach its proper operating temperature within a predetermined time an “Low Heat Error will occur. An error message will be displayed on the Control Panel alerting the customer. The engine stops all functions and keeps it at the error state until the issue is resoled by a qualied technician.

• Over Heat Error

If the Fuser Unit at any time exceeds the specied range [too hot] for proper operating temperature an “Over Heat Error will occur. An error message will be displayed on the Control Panel alerting the customer. The engine stops all functions and keeps it at the error state until the issue is resoled by a qualied technician.

2.2.5.4 LSU

LSU receives the image data from PVC or HPVC and makes 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 specied 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 to the customer.

• By Hsync : When the polygon motor is ready, the LSU sends out the signal called Hsync and it is used to

synchronize with each image line. So, if the engine does not detect consecutively the signal for a xed time, it denes 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 to the customer. LSU Error Recovery: If the LReady or Hsync error occurs the paper is exited with no image on it. 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.
