    MAINTENANCE AND INSPECTION

    CHAPTER 1 MAINTENANCE AND INSPECTION

    I . Servicing ChartThe machine does not have part that require periodical servicing. So that its parts may last

    longer, however, observe the following during visits to the users for replacement of consumablesor the like:

    ChecksCheck the general condition.Check faulty copies.a. Image densityb. White background (for

    soiling)c. Characters (for clarity)d. Leading edge margine. Left/right marginf. Trailing edge marging. Fixing, registration (for

    displacement), back (forsoiling)

    h. Abnormal sound

    While the power switch is onand the lever of the leakagebreaker is at ON, press thetest switch. If normal, thelever will shift to OFF to turnoff the power; otherwise,replace the leakage breaker,and make a check onceagain.

    Enter the result of checkingthe leakage breakers.

    RemarksWorkReport to the person in charge.Record the counter reading.Make test copies in Direct,Reduce, and Enlarge modes.

    Clean any soiled areas. (See thenext page for items.)Make test copies.Press the leakage breaker testswitch of the reader unit and theprinter unit to make sure eachoperates normally.Thereafter, turn off the powerswitch, and shift the lever to ON;then, turn on the power switch.

    Caution:Check to make sure thatgrounding is made correctly.Otherwise, leakage may nottrip the breakers.

    Execute auto gradation correctionin user mode.Make sample copies.Put the sample copies in order,and clean up the area around themachine.Record the counter reading.Fill out the Service Sheet, andreport to the person in charge.

    3. Replacing the Toner Cartridge

    Caution:Never throw the toner cartridge into fire.The toner will catch fire, causing burnsor fires.Be sure to use a toner cartrdige speciallydesigned for the machine.

    1) Open the upper cover.

    2) Hold the toner cartridge by its grips withboth your hands. Then, lift it to remove.

    3) Take the new toner cartridge out of itsprotective bag.Keep the bag. You will need it when re-moving the toner cartridge.

    4) Pull up the tape [1] slowly to remove it to-gether with the protective sheet [2].

    5) Rotate the toner cartridge as shown slowlyfive to six times as shown to even out thetoner inside it.

    6) Place the toner cartridge on a firm, levelplace.

    7) While holding the toner cartridge with onehand, shift the orange tab and pull itslowly so that the sealing tape (about 71cm in length) is completely out of the car-tridge.

    4. Correcting the Displacement of Images in Main Scanning Direction (eachcassette; adjusting the margin)

    If the image in main scanning direction is displaced or the margin shows a discrepancy whenthe upper cassette or the lower cassette is used as the source of paper, adjust the margin as follows:

    Reference:The multifeeder or the duplex unit (accessory) do not require adjustment of the margin.

    1) Remove each cassette from the machine, and adjust the roll in the cassette with a screwdriverto eliminate displacement of images.

    The printer driver checker is designed to operate the printer unit on its own for making checkson the printer unit; the checker may be used for the following three functions:

    a. A solid black, horizontal line, vertical line, or solid white image may be printed on the printerunit. A choice may be made of the pickup slot and the delivery slot.

    b. The state of each sensor used in the printer unit may be monitored, and solenoids, motors, andother loads may be forced to operate.

    c. If a fault has occurred, the error data sent to the video controller (external device) from theprinter unit may be indicated using the LEDs of the checker.

    G. Variable Resistors (VR), Light-Emitting Diodes, and CheckPins by PCB

    Of the variable resistors (VR), light-emitting diodes (LED), and check pins used in the ma-chine, those needed in the field are discussed.

    Caution:Do not touch the VRs or check pins not found in the lists. They are for use at the factory only,and require special tools and a level of accuracy based on correct measurement.

    Caution:1. Some LEDs emit dim light because of leakage current when they are off; this is a normal

    condition, and must be kept in mind.2. VRs that may be use in the field ...............................

    Caution:If you used Adjust, Function, or Option mode, be sure to turn off and then on the power afterexecuting it.

    3. Backing Up the RAMEach reader is adjusted before shipment, and the settings are recorded on the service label

    (back of the front cover).

    Replacing the reader controller PCB or clearing the RAM affects these settings. Be sure toenter the new settings in service mode.

    The printer unit does not have a service label.If you made adjustments or changed the settings of service mode in the field, be sure to record

    the new settings on the service label.
