Chapter 2 Machine Operations

The main control PCB controls the operations of all machine functions. Jumper JP1 on the main control PCB controls the data memory back-up. Memory data that is backed-up in the event of a power failure includes any stored documents. Jumper JP2 on the main control PCB controls the programmable data memory back-up. Memory data that is backed-up in the event of a power failure includes user programmed information such as the date, time, TTI, autodialer, memory switches, etc. If the Passcode is forgotten, removing JP2 will clear all User Settings. NOTE: JP1, JP2, should remain in the "ON" position at all times. Be sure to check this on all replacement boards.

Main control PCB block diagram The main control unit controls all function of the machine. Following are its components: Fax Engine CPU -- The CPU is the core of the control section. It controls all other sections. Scanner Control --- Processes the signal from the Charge Coupled Device (CCD). Modem --- The modem facilitates modulation and demodulation of data for fax communication.

Memory (EPROM, SRAM, DRAM) EPROM -- - The EPROM contains all program instructions for unit operation. SRAM --- The SRAM, which is backed-up by a lithium battery, is used to store user programmed information. DRAM --- The DRAM, which is backed-up by a battery, is used to store memorized documents along with being a buffer.

Chapter 2 Machine Operations

The CCD (Charge Coupled Device) includes the photo sensitive device, charge transfer registers and output stage. The photo sensitive device is a MOS capacitor. It receives light which is reflected from the surface of the document through the lens and converts the received light energy into a series of electrical signals. These signals are then stored as a charge. The charge transfer registers send the signals sequentially to the output stage which converts them into appropriate voltages representing black and white images. The output stage sends voltages to the Main Control PCB for further processing.

Chapter 2 Machine Operations

Document separation is the process that allows a muliti-page document to feed through the scanner one page at a time. Separation occurs through the action of the separator roller and retard roller. As shown in the illustrations, documents in the feeder are pressed against the separator roller. The bottom document is separated from the remaining documents by the friction of the retard roller.

Following document separation, the feed roller advances the document. As it advances, the leading edge of the document activates the Document Sensor 2(DS2). Once DS2 is activated, the feed roller continues to rotate until the document reaches the scan wait position. The machine uses the distance from DS2 to the scan wait position and the diameter of the feed roller to determine the number of rotations necessary to feed the document to the scan wait position.

When the document reaches the scan wait position, the machine waits for the next command. It will start scanning the document when either the start or copy key is pressed. The light from the scanner lamp strikes the face of the document and is reflected into the lens through mirrors A, B, and C. In case the light intensity along the length of the scanner lamp is not uniform, shading compensation is provided to ensure even illumination.

As the reflected image passes through the lens, it is focused onto the charged coupled device(CCD). The CCD then converts the dark and light areas of the image into electrical impulses, or image data. Circuits on the main control PC board encode the image data and send it to the modem where it is modulated. The modulated signal is then placed onto the telephone line by the NCU. When DS2 detects the trailing edge of the document, the image signal output is turned off. The scanner continues to remain active for a few more seconds in case there is another document to follow.

Incoming data is received from the telephone line by the NCU and sent to the main control PC board. The modem, located on the main control board, demodulates the data. The data is then sent to the printer for image processing. The image processing is roughly divided into the following steps: 1. 2. 3. 4. 5. Drum Charging Drum Exposure Development Image Transfer Fusing

Please see the following pages for additional explanation of the before mentioned processes.

The PC Drum is charged with static electricity before laser exposure. The Rotating Charge Brush and the Precharge-film are used to charge the surface of the drum. The rotating brush and the Precharge-film charging generate ozone in the printer. Because the charge is placed directly on the PC Drum, it can be charged by a low voltage. At the same time, the PC Drum can be evenly charged. The Precharge-film supplies the charge to the Rotating Charge Brush to improve the charging efficiency. The Rotating Charge Brush is turned by the Main Motor.

A electrostatic latent image is made by the laser beam emitted from the Print Head Unit.



Sub-scanning Direction (vertical)

When the printer receives the PRINT signal, the Polygon Motor and the Main Motor rotate and paper is fed into the printer. The printing in the sub-scanning direction starts when the PWB-P sends the VIDEO signal to the Printer Head at a specified time after the leading edge of the paper activates the Paper Sensor (TOD signal). The print starting position of the 2nd line is determined by delaying the VIDEO signal.



In the scanning direction (horizontal)

The SOS (Start Of Scan) Sensor is installed on the Laser Diode Drive (PWB-D) to synchronize the laser timing for each scan line. NOTE: Do NOT clean the lenses or mirrors in the Print Head Unit.

The toner image transferred to the paper is securely fixed by a heat roller fusing system. The toner image is fused by Upper Fusing Roller heated by the Heater Lamp, and securely fixed by the pressure between the Upper and Lower Fusing Rollers. A Thermistor (TH1) detects and controls the Upper Fusing Roller temperature. The Thermal Fuse (TF1) opens when the temperature becomes approx. 133C and shuts down the power to the Heater Lamp.

Chapter 2 Machine Operations

The Thermistor (TH1 detects the surface temperature of the Upper Fusing Roller and inputs that analog voltage into IC1-77. Corresponding to this data, the Heater Lamp ON/OFF signal is output from IC1-54, causing the Heater Lamp (H1) to turn ON or OFF to control the fusing temperature. If the Heater Lamp is still on after the Thermistor detects a high temperature malfunction (the surface temperature of the Upper Fusing Roller exceeds 200 C), the signal from IC1-75 changes from H to L to turn OFF the Heater Lamp.

1. Warm Up - After the initialization of the printer, warm up of the printer starts and the Heater Lamp turns ON until the temperature of the Upper Fusing Roller reaches approx. 172 C. 2. Standby - In standby mode, the temperature of the Upper Fusing Roller is maintained at 156 C. After 3 minutes, the printer turns to power save mode. The fuser is kept at low temperature. 3. Print Cycle - When the printer obtains the printing command from its controller, the Upper Fusing Roller is maintained at 172 C. 4. Standby at Low - The Upper Fusing Roller is maintained at temperature 112 C. Copyright 1997, Okidata, Division of OKI America, Inc. All rights reserved.
