15.3. Printing Operation Principle
15.3.1. Process Chart and Process BIAS
15.3.2. CHARGING
Charging is the stage that keeps the surface of the sensitive drum a fixed electric potential. The sensitive drum is the Organic Photo Conductor (OPC), which is a electric conductive cylinder whose surface is covered with the Charge Generation Transfer Layer (CGTL). When the charging bias (DC +4.35kv) is added and the plus charge is supplied to the OPC surface while charging, the whole surface potential of the drum is +475V.
Charging Part
228
KX-MB772CX-V1
15.3.3. Exposing
When the drum which is charged with the fixed electric charge is irradiated by the laser beam, the plus charge and minus charge are generated at the Charge Generation Transfer Layer. Passing through the Charge Generation Transfer Layer which conducts the minus charge, the plus-charged drum's surface is neutralized to be skipped. Then the plus charge goes to the ground from the electric conductive cylinder. Consequently the charge of the part which is not exposed remains as it is, and the electric potential of the scanned part changes. At that time an invisible image is created on the drum.

15.3.5. Developing and Transcription
The developing is the stage that the OPC drum with an invisible image is changed to visible by the toner. The drum unit consists of mixing paddle, toner supply roller, developing roller, developing blade, charge wire, grid plate and OPC drum. The bias voltage is added to the developing roller and toner supply roller. Firstly the toner is mixed up in the mixing paddle and plus-charged by triboelectricity, then led to the toner supply roller. Secondly the potential difference causes to send the toner to the developing roller from the toner supply roller. The supplied toner to the developing roller is kept to a certain layer thickness by the developing blade and also it is charged by triboelectricity. Consequently the toner is transferred to the surface of the exposed OPC drum by the potential difference between the developing roller and OPC drum's surface. The transfer is the stage that the created image on the OPC drum is transferred to the paper. When the transfer roller is minuscharged with the image, the plus-charged toner particles are gathered on the surface of the drum and transferred to the paper.
Developing and Transcription Part

KX-MB772CX-V1
15.3.6. Cleaning of Transfer Roller
The toner attached to the surface of the OPC drum is transferred to the paper at the transcription stage, but a part of the toner remains. The cleaning is the stage that cleans the remain toner after the transcription stage. The remain toner on the drum and the toner which was attached to the place where the laser beam didn't scan are gathered to the developing roller to be used again. After paper jam or replacing toner and drum unit, the transfer roller is plus-charged to eliminate the plus-charged toner.

KX-MB772CX-V1
15.3.7. Fixing
On the process of the transfer, the transferred toner is weakly attached on the paper. Fixing means the process to fix the toner on the paper permanently. The fixing part melts the toner at the high temperature using the halogen heater. The toner is fixed on the paper by the heat and pressure through the fixing part with the image. The surface of the heat roller is rosined by Teflon and lubricated to prevent from attaching the toners. The press roller is made of silicon, and its spring compresses the melted toner.
Fixing Part
The fixing part becomes high temperature, so the thermistor and the two thermostats are provided. 1. Thermistor The thermistor touches the heat roller and check the temperature to feed back to the control circuit. The surface temperature should be kept 195°C while printing. 2. Thermostat The thermostat is located near the heat roller, and it turns OFF the power when the temperature around the thermostat becomes over 160°C.

15.5. How to Replace the Flat Package IC
Even if you do not have the special tools (for example, a spot heater) to remove the Flat IC, with some solder (large amount), a soldering iron and a cutter knife, you can easily remove the ICs that have more than 100 pins.
15.5.1. Preparation
· PbF (: Pb free) Solder · Soldering Iron Tip Temperature of 700°F ± 20°F (370°C ± 10°C) Note: We recommend a 30 to 40 Watt soldering iron. An expert may be able to use a 60 to 80 Watt iron where someone with less experience could overheat and damage the PCB foil. · Flux Recommended Flux: Specific Gravity 0.82. Type RMA (lower residue, non-cleaning type) Note: See About Lead Free Solder (PbF: Pb free) (P.8.)
15.5.2. Flat Package IC Removal Procedure
1. Put plenty of solder on the IC pins so that the pins can be completely covered. Note: If the IC pins are not soldered enough, you may give pressure to the P.C. board when cutting the pins with a cutter.
2. Make a few cuts into the joint (between the IC and its pins) first and then cut off the pins thoroughly.
3. While the solder melts, remove it together with the IC pins.
When you attach a new IC to the board, remove all solder left on the land with some tools like a soldering wire. If some solder is left at the joint on the board, the new IC will not be attached properly.

15.5.3. Flat Package IC Installation Procedure
1. Temporarily fix the FLAT PACKAGE IC, soldering the two marked pins.
*Check the accuracy of the IC setting with the corresponding soldering foil. 2. Apply flux to all pins of the FLAT PACKAGE IC.
3. Solder the pins, sliding the soldering iron in the direction of the arrow.
15.5.4. Bridge Modification Procedure
1. Lightly resolder the bridged portion. 2. Remove the remaining solder along the pins using a soldering iron as shown in the figure below.

15.6. Main Board Section
When the unit fails to boot up the system, take the troubleshooting procedures very carefully. It may have a serious problem. The symptom: No response when the power is turned on. (No LCD display, and keys are not accepted.) The first step is to check the power source. If there is no problem with the power supply unit, the problem may lie in the digital unit (main board). As there are many potential causes in this case (ASIC, DRAM, etc.), it may be difficult to specify what you should check first. If a mistake is made in the order of checks, a normal part may be determined faulty, wasting both time and money. Although the tendency is to regard the problem as a serious one (IC malfunction, etc.), usually most cases are caused by solder faults (poor contact due to a tunnel in the solder, signal short circuit due to solder waste).
Note: 1. Electrical continuity may have existed at the factory check, but a faulty contact occurred as a result of vibration, etc., during transport. 2. Solder waste remaining on the board may get caught under the IC during transport, causing a short circuit. Before we begin mass production, several hundred trial units are produced at the plant, various tests are applied and any malfunctions are analyzed. (In past experiences, digital IC (especially, DRAM and ROM) malfunctions are extremely rare after installation in the product.) This may be repaired by replacing the IC, (DRAM etc.). However, the real cause may not have been an IC malfunction but a soldering fault instead. Soldering faults difficult to detect with the naked eye are common, particularly for ASIC and RA (Resistor Array). But if you have an oscilloscope, you can easily determine the problem site or IC malfunction by checking the main signal lines. Even if you don't have such a measuring instrument, by checking each main signal line and resoldering it, in many cases the problem will be resolved. An explanation of the main signals (for booting up the unit) is presented below.
What are the main signals for booting up the unit? Please refer to GENERAL BLOCK DIAGRAM (P.14). The ASIC (IC300) controls all the other digital ICs. When the power is turned on, the ASIC retrieves the operation code stored in the ROM (IC402), then follows the instructions for controlling each IC. All ICs have some inner registers that are assigned to a certain address. It is the address bus by which the ASIC designates the location inside each IC. And the data bus reads or writes the data in order to transmit the instructions from the ASIC to the ICs. These signal lines are all controlled by voltages of 3.3V (H) or 0V (L).
