Page 25: Progressing With The Troubleshooting
Troubleshooting in this manual assumes use of Diag. tools (maintenance tools). However, the troubleshooting allows for the case where the Diag tools are not used. You can correct troubles according to these troubleshooting procedures after understanding them well. 1. Progressing with the Troubleshooting After making sure of actual condition of a trouble, proceed with the troubleshooting process making use of the Fault Isolation Procedure (FIP), “Operation of Diagostics”...
Page 26: Preparatory Requirements
The laser printer is properly grounded. The laser printer is not installed at a place subjected to too high temperature, too high humidity, too low temperature, too low humidity or rapid change of temperature. The laser printer is not installed close to water service, humidifier, heat generating unit, or fire, in very dusty place, or a place exposed to air flow from the air conditioning system.
Page 27: Cautions For Service Operations
1.3 Cautions for Service Operations Be sure to remove the power cord except when it is specifically required. If the printer is kept ON, never touch the conductive parts while it is not specifically required. The power switch/inlet of LVPS is live even while the power supply is cut off. Never touch the live parts.
Page 28: Cautions For Fip Use
1.4 Cautions for FIP Use It is assumed in the FIP that the printer controller (CONTROLLER PWB) is normally functioning. If the trouble cannot be corrected by troubleshooting, replace the printer controller with a normal one and check for proper operation again.
Page 29 (HIGH ASSY). 15) In the FIP, the paper pick-up unit by means of the paper tray at the lower part of the printer is referred to as "try 1", the first level of the paper pick-up unit feeder unit as "try 2", and the second level as the "tray3".

1. Printing Process 1.1 Summary of Printing Process This printer is a "Full-color laser printer" which applies the principal of an electrophotographic recording system. The tandem system comprising a drum and developing unit respectively for each color of yellow, magenta, cyan and black (Y, M, C and K) places toner image of each color on paper producing full-color prints finally through 3 intermediate transfer units (IDT 1: 2, IDT 2: 1).
Page 316: Schematic Diagram For Printing Processes
1.2 Schematic Diagram for Printing Processes Outline of printing processes is shown in the figures below. TCRU ASSY(Y) [(3) Development] TCRU ASSY(M) [(3) Development] TCRU ASSY(C) [(3) Development] TCRU ASSY(K) [(3) Development] PHD ASSY is integrated major units of printing processes. It is composed as follows. [(1) Changing with electricity] [(1) Changing with electricity] Developer(Y)
Page 317: Description Of Printing Process Techniques
1.3 Description of Printing Process Techniques 1.3.1 Charging with electricity In the charging process, the drum surface rotating at a constant speed is charged uniformly with negative electricity by discharging of RTC (Rubber Tube Charge: Charged film). This process is performed in parallel for yellow, magenta, cyan and black colors. ✧...
Page 318 Quad Beam Laser Diode ✧ The laser beams are emitted based on the print data (image data) from the printer controller. When the print data instructs to print pixel points, laser beams are generated and when the print data instructs not to print, no laser beams are generated. (On the areas which are developed by toner, the laser beams light up and areas which are not developed by toner, laser beams go out.)

Page 324 1.3.5 Secondary transfer (IDT 1 -> IDT 2) In the secondary transfer process, the toner image formed on the IDT 1 surface is transferred onto the surface of the IDT 2 (Intermediate Drum Transfer 1: intermediate transfer roll 2). Two color toner image transferred onto the 2 IDT 1 is transferred to the IDT 2. Thus, 4 color toner image are compiled on the IDT 2 as finished toner image.

Page 326 1.3.7 Tertiary transfer (IDT 2 - paper) In the tertiary transfer process, finished toner image formed on the IDT 2 surface is transferred onto the paper under the voltage supplied to the BTR (Bias Transfer Roll). ✧ BTR is composed in the BTR ASSY. BTR is a conductive roll and receives positive high current from HVPS.
Page 327 1.3.10 Fixing In the fixing process, toner is fixed on the paper by heat and pressure. ✧ Finished toner image transferred from the belt is easily broken only by touching it with fingers. The toner image is fixed on the paper with the FUSER ASSY (fixing unit). The toner melts by heat of the HEAT ROLL with the Heater lamp as the heat source and is deposited on the paper under pressure given by the belt opposed against the heat roll.
Page 328 1.3.11 Cleaning (general) In the cleaning (general) process, toner stored in the IDT 1 cleaner and IDT 2 cleaner after the finished toner image is transferred onto the paper and the toner remaining on the BTR are removed. ✧ The toner not completely transferred in the "secondary transfer" and "tertiary transfer" processes is held temporarily in the IDT1 Cleaner and IDT2 Cleaner.
Page 329 Refresher and RTC High voltage of the polarity (negative) reverse to that at the printing transfer is applied to the IDT1, IDT2, and BTR. At this time, the drum surface is charged negatively by negative voltage of the IDT1. The toner (positive polarity) remaining in the Refresher and RTC are move to the drum electrically by transforming the Refresher and RTC to 0V.

Page 362: Process Control
7.4 Process Control For a stable printing, the parameters related to the image forming must be corrected as necessary. The control of entire printing process including parameter correction control is called "process control". Mainly, the following two controls are made: •...
Page 363 7.4.2 Toner Density Control The toner density must be kept constant to attain stable printing image. To keep the toner density constant, the toner should be dispensed exactly by the quantity consumed for the printing. This system is the PCDC. However, the system with only the PCDC generates a difference from target toner density, thus requiring the system to correct this error.
Page 364 7.4.3 High Area Coverage Mode A continuous printing of the image of area coverage exceeding the toner dispense capability causes the toner density in the developer to be lowered. The High Area Coverage Mode extends the next page feed and dispenses the toner during this time, if the toner dispense time reached the specified value during a continuous printing.
Page 365: Color Registration Control
7.5 Color Registration Control The printer uses a tandem system where the drums and developers exclusively for yellow, magenta, cyan, and black are arranged respectively. The images are formed on the drums of respective colors and they are overlapped to form one image, and in this case a color shift may occur. The color registration control calculates how much the registration is shifted, and adjusts the ROS write timing.

7.7.1 SENSOR TONER LOW The SENSOR TONER LOW is provided for each color, but the printer cannot detect all colors at a time, but detects one color each. It detects one color per 3.5 seconds, thus requiring 14 seconds for detecting four colors.

7.8 Fuser Control 7.8.1 Fuser temperature control As for the fuser temperature control, the target temperature is set, then the Heat Roll surface temperature is controlled so as to be the target temperature by turning on/off the Heater Lamp. The Heat Roll surface temperature is detected by the Temp Sensor. The Temp Sensor detects the temperature and the resistance value for disconnection sensing alternately at 40ms cycles.
