The scanner unit consists of a scanner top cover, CCD unit and scanner base.Then, the machine starts scanning, and the CCD drive mechanism is started. When the machine starts simplex scanning, the ADF motor is rotated clockwise, the pick-up roller draws the document, and the separation roller and separation pad send a sheet of the document to the ADF one by one from the top page of the stacked documents. When the machine starts duplex scanning, the ADF motor is rotated clockwise, the pick-up roller draws the document, and the separation roller and separation pad send a sheet of the document to the ADF one by one from the top page of the stacked documents. The document is passed through the paper feed rollers 1, 2 and 3, and ejected to the document cover by the eject roller. SB roller ASSY Paper feed roller 2 Eject roller Paper feed roller 3. Pinch roller Feed roller TR Regist roller Pressure roller PE actuator. When the paper tray (Tray1 cassette) is installed into the machine, the lift gear 46 is rotated, and the motor drive is transmitted to the plate ASSY so that it is pushed up. The developer consists of a non-magnetic toner. The developer roller is made of conductive rubber and the supply roller (which is also made of conductive sponge) rotate against each other. The toner is charged and carried from the supply roller to the developer roller. The thermistor keeps the surface temperature of the heat roller constant by detecting the surface temperature of the heat roller and turning on or off the halogen heater lamp. Afterwards, the paper is ejected from the duplex tray to the path through the regist roller and the transfer roller to the transfer block in the drum unit again for process of printing on the back of sheet. When the separation roller is driven, therefore, the feed roller is also driven. At this time, the recording paper is drawn out of the MP tray by rotation of the feed roller contacted with the recording paper.

In the case of low-duty printing, “Toner Life End”. The toner used for the machine has a property that print density is light first and gradually darker in the course of usage. The charge is generated by ionization of the corona wire, which has a DC bias from the high-voltage power supply applied to it. The service personnel should instruct end users to follow the transfer procedure given in this chapter if the machine at the user site cannot print received data due to the printing mechanism defective. The disassembly order flow provided enables you to see at a glance the quickest way to get to component(s) involved. At the start of a disassembly job, you check the disassembly order flow that guides you through a shortcut to the object components. How to Access the Object Component - On the next page is a disassembly flowchart which helps you access the object components. DX feed ASSY Fig. 5-3 5.1.4 Paper Tray (1) Close the Front cover.

You can customize the EEPROM according to the shipment destination of the machine concerned. TIP: FAX models equipped with numerical keypads can enter the maintenance mode in the same way as conventional models;.
However, you can allow end users to access some of these under the guidance of service personnel (e.g., by telephone). The user-accessible functions (codes 06, 09, 10, 11, 12, 53, 54, 80, 82 and 87) are shaded in the table given on the previous. Entering the function code 01 initializes all of the EEPROM areas, but entering 91 does not initialize some areas, as listed below. Operating Procedure Implement the operating procedure below after scanning the document once at least, not immediately after the machine is turned on. Since the machine initializes the white and black level data and obtains the standard value for document scanning compensation when starting scanning the document, the correct data for compensation cannot be printed out even if this operation is implemented without scanning the document. When you fix the FAX equipment and check its operation, you need to perform this function right before packing and shipping it. The figure below shows test pattern. The firmware switches have been set at the factory in conformity to the communications standards and codes of each country.

If any error message appears, refer to this chapter to find which components should be checked or replaced. The latter half of this chapter provides sample problems that could occur in the main sections of the machine and related troubleshooting procedures.

It is impossible to anticipate all of the possible problems which may occur in future and determine the troubleshooting procedures, so this section covers some sample problems. Even if the same problem occurs again, follow the procedures in the table below. User Check (1) Check that the machine cable is not damaged or broken. Check also that the cable is connected to the correct interface connectors of both the machine and PC. High-voltage Check the connections of Replace the high-voltage power power supply the connector between the supply PCB. Possible cause Step Check Result Remedy Link lever Does the link lever work.

Even if the same image defect appears, the following procedures should be followed in the event of specific image defects. High temperature and high humidity conditions can increase the amount of background shading. (3) Clean the corona wire with the wire cleaner. (4) Try installing a new toner cartridge or drum unit. Drum unit Are the drum shaft and Clean the shaft and the drum electrode of the electrode. Install a new drum unit. Ground Possible cause Check Remedy Step Result contacts Corona failure Is the corona wire dirty. Clean the corona wire with the wire cleaner.

(2) Check the paper used meets the recommended paper specifications. (3) Clean the inside of the machine and the corona wire in the drum unit. Ground Possible cause Check. Install a new toner cartridge.
(3) Check the machine’s environment. High temperature and high humidity conditions can cause this problem. (4) Damp (wet) paper might be used. Refer to Step 1 in the table below and NOTE in the next page. Refer to Step 1 in the table below and NOTE in the previous page. Corona dirty Is the corona wire dirty? 1) Clean the corona wire. Drum Is the contact between the Clean contact electrode connection drum unit and machine both on the drum unit failure body connected correctly? A rough surfaced paper may cause the problem. (2) The toner cartridge may be damaged. Install a new toner cartridge. (3) The drum unit may be damaged, or may be nearly at the end of life. Install a new drum unit. User Check (1) Check if the machine cable is not too long. It is recommended to use a parallel cable of less than 2 meters (6.6 feet) in length. NOTE: This problem may appear if the data is too complex. Brother print servers have two LEDs on the back panel of the machine. If it is visible, then the connection is good. Otherwise, go to Step 5. Then, click OK. (5) Once your firewall is disabled, try reinstalling the Brother software package.
