Note: “596: Transmit level set” represents a service code. Refer to the SERVICE FUNCTION TABLE For the receiving problem, we have thought of causes other than in the software.

2.3.7.1.5. THE UNIT CAN COPY, BUT CANNOT EITHER TRANSMIT/RECEIVE LONG DISTANCE OR INTERNATIONL COMMUNICATIONS The following two causes can be considered for this symptom. Cause 1: The other party is executing automatic dialing, the call has been received by this unit, and the CED or DIS signal response time is too long.

is detected erroneously as the signal from FAX2. For a normal call, there is also a possibility that the echo of their own voice will make the call difficult to understand. For this reason, each station (station 1 and station 2) attaches echo cancelers (S1 and S2) for international lines or long distance lines.

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).
Page 92
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 DIGITAL BLOCK DIAGRAM The ASIC (IC604) controls all the other digital ICs.
Page 93
Normal Wave Patterns Remarks: For these reasons and the software sequence to boot up the unit, if you use an oscilloscope the judge whether a signal is OK or NG, you must check in the same order as in [List 1]. (IF the ASIC failed to access the ROM, the ASIC cannot access G/A or DRAM normally.) The digital circuit actually operates according to the timing combinations of these signals.
Page 94
Accordingly, the problem presented here is whether each IC outputs the correct signal. (See the I/O direction diagram on the next page.) In other words, is it constantly switching between 3.3 V (H) and 0 V (L) as described earlier. Note: All you have to do is check that the IC repeatedly outputs (H) 3.3 V and (L) 0 V.

2.3.9. ANALOG BOARD SECTION This chapter provides the testing procedures required for the analog parts. A signal route to be tested is determined depending upon purposes. For example, the handset TX route begins at the handset microphone and the signal is output to the telephone line. The signal mainly flowing on this route is analog.

Note: { }: Inside the digital board 2.3.9.2. DEFECTIVE ITS (Integrated Telephone System) SECTION 1. No handset and speakerphone transmission / reception Perform a signal test in the ITS or the NCU section and locate a defective point (where the signal disappears) on each route between the handset microphone and telephone line (sending), or between the telephone line and the handset speaker (receiving), or between the microphone and the telephone line (sending), or between the telephone line and the speaker (receiving).

Caution: If you find a melted fuse in the unit, do not turn on the power until you locate and repair the faulty parts (except for the fuse); otherwise the fuse will melt again and you cannot pinpoint the faulty point. In most cases, the symptom is that nothing is output.
Page 114
2.3.12.3. BROKEN PARTS REPAIR DETAILS (D101~D104) Check for a short-circuit in terminal 4. If D101~D104 is short-circuit, F101 will melt (open). In this case, replace all of the parts (D101~D104, F101). (Q101) The worst case of Q101 is a short-circuit between the Drain and Gate because damage expands to the peripheral circuit of Q101.

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.
Page 158
Recommended power consumption is between 30 W to 40 W. Temperature of Copper Rod 662 ± 50°F (350 ± 10°C) (An expert may handle a 60~80 W iron, but a beginner might damage the foil by overheating.) - Flux HI115 Specific gravity 0.863 (Original flux should be replaced daily.) 5.2.
Page 159
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.
Page 160
*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. 5.4. BRIDGE MODIFICATION PROCEDURE 1.

6. PRINTING OPERATION PRINCIPLE 6.1. PROCESS CHART AND PROCESS BIAS 6.2. 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 Layer (CGL) and Charge Transfer Layer (CTL).
Page 162
6.4. LASER SCANNING UNIT LOCATIONS 6.5. DEVELOPING AND TRANSCRIPTION The developing is the stage that the OPC drum with an invisible image is changed to visible by the toner. The developer consists of mixing paddle, toner supply roller, developing roller, developing blade and OPC drum.
Page 163
The values of developing bias and supply bias are different from the ones described in the Service Manual for FL501. The biases output from the unit of FL501 and FLM551 have the same voltage. However, the developing device of FA77D converts the developing and supply biases inside the developing device to improve the image quality.
Page 164
6.6. CLEANING 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.
Page 165
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.

6.9. IMAGE READING The Image Reading Part feeds and ejects the document when copying or scanning. The image reading part consists of the followings. 6.9.1. Automatic Document Feeder The automatic document feeder consists of separation roller, document feed roller, separation pad, springs, etc.
Page 168
reading the document, the motor is driven again by the operation of the user to move the roller at a fixed speed. The documents are fed one by one separated by the separation pad. The spring plate adds the pressure to the document so that the separation pad can separate the documents properly.
Page 169
Document feeding mode - The motor pinion rotates in the direction shown in the figure. - Although the GEAR ONEWAY 1A rotates, built-in ONEWAY CLUTCH disturbs to transfer the driving power to the next gear. - The FEED ROLLER and SEPARATION ROLLER perform feeding and separating the documents.
Page 170
- The motor pinion rotates in the direction shown in the figure. - The gears of fixing and developing parts are driven by the GEAR ONEWAY 1A. - The GEAR PLANET is separated from the GEAR DOCUMENT FEED ROLLER. - The GEAR DOCUMENT SEPARATION ROLLER runs idle and does not transfer the driving power to the roller.
Page 171
During printing - When the SOLENOID is turned ON, the HOOK GEAR FIX is hooked on the RING of GEAR CLUTCH. It causes the GEAR PICKUP PAPER to rotate. - At the same time, CAM's rotation lifts up the PLATE LIFT PAPER. The recording paper is pressed by the PICKUP ROLLER and the top paper is separated and fed.
