2.2 Main Control PCBThe main control PCB controls the operations of all machine functions. Jumper JP2 on the main control PCB is used for battery back up of the SDRAM. Removing JP2 will initialize the SDRAM. If the power is turned off, the battery will provide up to 72 hours (8MB) of back up when fully charged. Jumper JP1 on the main control PCB is used for battery back up of the SRAM. All user programmed data and internal memory switch settings are held in SRAM. Removing JP1 will initialize the SRAM. If the power is turned off, the battery will provide up to five years of back up when fully charged. NOTE: JP1, JP2 should remain in the "ON" position at all times. Memory (FLASH MEMORY, SRAM, SDRAM) FLASH MEMORY -- The FLASH MEMORY 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. SDRAM --The SDRAM is used for buffer, which is backed-up by a battery is used to store memorized documents. NOTE: The SDRAM back-up battery is connected to the PCB MAIN. When the PCB MAIN is replaced, the connection will be lost. Therefore, please reenter the date and time, after you have replaced the PCB MAIN. (Press MENU, 2, 1, 0, 9, and enter month, then day, year, hour and minute in 24-hour format.) NOTE: Turning parameters for Color(R,G,B) and Gray mode are stored in the EEPROM(IC42). When the PCB MAIN is replaced, the EEPROM on malfunction PCB should be replaced to the new PCB.DISPLAY KEY NCU PCB PANEL G/A

2.6 Document Scanning Sequence2.6.1 ADF DetectionWhen a document is placed into the document feeder, Document Sensor 1 (DS1) is activated and you will hear the short beep. The document will be transferred when the start key is pressed. Document separation is the process that allows a multi-page document to go through the scanner one page at a time. The bottom document is separated from the remaining documents by the friction of the separator pad. Following document separation, the feed roller causes the document to advance. As it advances, the leading edge of the document activates the Document Sensor 2 (DS2) sensor. Once DS2 is activated, the feed roller continues to rotate until the document reaches the scan position. The machine uses the distance from DS2 to the scan position and the diameter of the feed roller to determine the number of rotations necessary to feed the document to the scan position. When the document reaches the scan position, 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. 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. The scanned document is discharged through the document exit by the exit roller.Separator roller Separator pad Pickup roller DS1 (Feeler) Exit roller

2.6.2 FBS sectionLight reflected from the original passes through three mirrors and a lens to form a reduced image on the CCD Sensor as the Scanner Motor moves the Scanner. The CCD sensor converts the light pattern (image data) into an electrical image signal. The electrical image signal is then output to the Main Board.

2.6.2.2 Scanner frame Moving MechanismDuring a scan, the scanner frame projects an even amount of light from the Exposure Lamp onto the entire surface of the original. The light is reflected from the original to the Mirror through the lens to the CCD. The scanner frame is driven by the FBS Motor and front and rear Scanner Drive belts. Scanner speed is determined by the set zoom ratio in reference to the full size mode. The scanner frame is at home position where ADF scanning begins. The home sensor watches this position.

2.8 Image ProcessingIncoming data is received from the telephone line by the NCU and sent to the main control PCB. The modem, located on the main control PCB, demodulates the data. The data is then sent to the printer for image processing. The image processing is roughly divide into the following steps: 1. Drum Charging 2. Drum Exposure 3. Development 4. Image transfer 5. Fusing 6. Erasing 7. Cleaning

2.8.1 Drum ChargeThe Drum is charged with corona discharge before LED exposure. A charge wire and a charge grid are used for the charging method. The corona discharge generates little ozone in the printer.

2.8.2 Drum ExposureThe light makes an invisible static image from the LED print head. The LED print head, located inside the printer cover, closes down over the drum and projects light onto the drum surface. When the document is to be printed, individual elements in the LED print head turn on and expose the drum wherever a dark area should appear in the document.

2.8.3 DevelopmentToner is applied to the invisible static image on the Drum and a toner image is created on the surface.

Carries the toner to the Drum surface for development. Exposed by LED light to create an invisible image and rotates to carry the developed image to the paper surface.

2.8.4 Image TransferImage transfer is the process of transferring the toner image created on the Drum in the developing process to paper. There is no blur of toner because the paper is always pressed by the Drum and the Image Transfer Roller.

2.8.5 ErasingAn LED lamp exposes the Drum surface. When it is exposed the drum charge erases. This helps the drum to be recharged evenly at the next step of charging.

Drum LED Lamp

2.8.6 CleaningThe residual toner or paper dust must be removed from the drum. Paper dust is removed from the drum surface by a rubber roller. And then by a metallic roller, and finally scraped off. The residual toner is removed by the developing roller and toner supply roller, and is recycled.

2.8.7 FusingAn OverviewThe toner image transferred on to the paper is securely fixed. A heat roller system is used as the fusing system. The toner image is fused by Heater Roller heated by the Heater Lamp, and securely fixed by the pressure between the Heater roller and Press rollers. A Thermistor detects and controls the Heater Roller temperature. The Thermostat functions when the Heater Lamp is not turned OFF even if the Thermistor detects a high temperature malfunction.

Fusing Temperature Control CircuitThe Thermistor detects the surface temperature of the Heater Roller and inputs that analog voltage into the Main Control PCB. Corresponding to this data, the Heater Lamp ON/OFF signal is output to the Heater ON/OFF switch of the power supply unit, causing the Heater Lamp to turn ON or OFF to control the fusing temperature. When the Heater Lamp is not turned OFF even if the Thermistor detects a high temperature malfunction, the thermostat shuts down the power to the heater lamp. When the thermostat is malfunction, the thermal cut-off shuts down the power to the heater lamp.AC InletL N
