    [9] ADJUSTMENTS
    1. Optical section
    A. Copy magnification ratio adjustment
    The copy magnification ratio must be adjusted in the main scan-
    ning direction and in the sub scanning direction. To adjust, use
    SIM 48-1.
    (1) Outline
    The main scanning (front/rear) direction magnification ratio adjust-
    ment is made automatically or manually.
    Automatic adjustment: The width of the reference line marked on
    the shading correction plate is scanned to perform the main scan-
    ning (front/rear) direction magnification ratio adjustment automati-
    cally.
    Manual adjustment: The adjustment is made by [Copy quantity]
    keys operations. (In either of the automatic and manual adjust-
    ments, the zoom data register set value is changed for adjustment.)
    The magnification ratio in the sub scanning direction is adjusted by
    changing the carriage (scanner) scanning speed.
    (2) Main scanning direction magnification ratio 
    adjustment
    a. Cases when the adjustment is required
    1) When the main PWB is replaced.
    2) When the EEPROM in the main PWB is replaced.
    3) When U2 trouble occurs.
    4) When repairing or replacing the optical section.
    b. Necessary tools
     Screwdriver (+)
    
    c. Adjustment procedure
    1) Set the scale vertically on the document table. (Use a long
    scale for precise adjustment.)
    2) Set the copy magnification ratio to 100%.
    3) Make a copy on A4 or 81/2 x 11 paper.
    4) Measure the length of the copied scale image.5) Calculate the main scanning direction magnification ratio. 
    Main scanning direction magnification ratio
    6) Check that the copy magnification ratio is within the specified
    range. If it is not within the specified range, perform the follow-
    ing procedures.
    7) Execute SIM 48-1 to select the main scanning direction copy
    magnification ratio adjustment mode.
    To select the adjustment mode, use the [Exposure mode selec-
    tor] key.
    In the case of the automatic adjustment, when the START switch is
    pressed, the mirror base unit moves to the white plate for shading
    to scan the width of the reference line, calculating the correction
    value and displaying and storing this value.
    After execution of the automatic adjustment, go out from the simu-
    lation mode and make a copy to check the magnification ratio.
    If the magnification ratio is not in the specified range (100 ± 1.0%),
    manually adjust as follows.
    8) Enter the new set value of main scanning direction copy magni-
    fication ratio with the copy quantity key, and press the [START]
    key.
    9) Change the set value and repeat the adjustment until the ratio
    is within the specified range.
    When the set value is changed by 1, the magnification ratio is
    changed by 0.1%.
    (3) Sub scanning direction copy magnification ratio
    a. Cases when the adjustment is required
    1) When the scanner unit drive section is disassembled or the part
    is replaced.
    2) When the main PWB is replaced.
    3) When the EEPROM in the main PWB is replaced.
    4) When U2 trouble occurs.

    3) Set the print start position (AE lamp ON) (A), the lead edge void
    amount (TEXT lamp ON) (B), and the scan start position
    (PHOTO lamp ON) (C) to 0, and make a copy of a scale at
    100%.
    4) Measure the image loss amount (R mm) of the scale image.
    Set C = 10 X R (mm). (Example: Set the value of C to 30.)
    When the value of C is increased by 10, the image loss is
    decreased by 1mm. (Default: 50)
    5) Measure the distance (H mm) between the paper lead edge
    and the image print start position.
    Set A = 10 X H (mm). (Example: Set the value of A to 50.)
    When the value of A is increased by 10, the image lead edge is
    shifted to the paper lead edge by 1mm. (Default: 50)
    6) Set the lead edge void amount to B = 50 (2.5mm).
    When the value of B is increased by 10, the void amount is
    increased by about 1mm. For 25 or less, however, the void
    amount becomes zero. (Default: 50)
    (2) Image rear edge void amount adjustment
    1) Set a scale to the rear edge section of A4 or 11 x 8 1/2 paper
    size as shown in the figure below, and cover it with B4 or 8 1/2
    x 14 paper.
    2) Execute SIM 50-01 to select the image rear edge void amount
    adjustment mode.
    The set adjustment value is displayed on the copy quantity dis-
    play.
    3) Make a copy and measure the void amount of image rear edge.4) If the measurement value is out of the specified range, change
    the set value and repeat the adjustment procedure.
    The default value is 50.
    Note:The rear edge void cannot be checked with the first sheet
    after entering the simulation mode, the first sheet after turn-
    ing off/on the power, or the first sheet after inserting the
    cassette. Use the second or later sheet to check the rear
    edge void.
    (3) Center offset adjustment
    1) Set the self-made test chart for the center position adjustment
    so that its center line is aligned with the center mark of the doc-
    ument guide.
     Test chart for the center position adjustment.
    Draw a line at the center of A4 or 8 1/2 x 11 paper in the paper
    transport direction.
    2) Execute SIM 50-10 to select the print center offset (cassette
    paper feed) adjustment mode.
    The set adjustment value is displayed on the copy quantity dis-
    play.
    3) Make a copy and check that the copied center line is properly
    positioned.
    The standard value is 0 ± 2mm from the paper center.
    4) If the measured value is out of the specified range, change the
    set value and repeat the adjustment procedure.
    When the set value is increased by 1, the copy image is
    shifted by 0.1mm toward the rear frame.
     For the manual paper feed, change the manual paper feed
    adjustment mode and perform the similar procedures.
     Since the document center offset is automatically adjusted by
    the CCD which scan the reference lines (F/R) on the back of
    document guide, there is no need to adjust manually.

    not reverse the sequence.
    Procedures
    1) Set the digital multi meter range to DC700V.
    2) Set the positive side of the test rod to the connector CN11-3
    (GRID) of high voltage section of the power PWB and set the
    negative side to the frame ground (power frame).
    3) Execute SIM 8-2. (The main charger output is supplied for 30
    sec in the grid voltage HIGH output mode.)
    4) Adjust the control volume (VRG1) so that the output voltage is
    580 ± 12V.
    B. DV bias check
    Procedures
    1) Set the digital multi meter range to DC500V.
    2) Set the positive side of the test rod to the connector CN-10-1
    (DV BIAS) and set the negative side to the frame ground
    (power frame).
    3) Execute SIM 8-1 to output the developing bias for 30sec, and
    check that the output is –400 ± 8V.
    4. SPF scan position automatic 
    adjustment (Option)
    Place a A4 paper (white chart) so that it covers the SPF scan glass
    and the OC glass together, and close the SPF.
    When simulation 53-08 is executed, the current adjustment value is
    displayed as the initial display.
    * Default is 1. Adjustment range is 1 – 99. Adjustment unit 1 =
    about 0.127mm
    * If the values are kept as the default values, SPF scan is not per-
    formed properly. The front area of the proper scan position may
    be scanned.
    In case of AUTO, press [START] key, and the mirror unit scans
    from the home position to the SPF scan position with the adjust-
    ment value displayed. The SPF glass cover edge position is calcu-
    lated from the difference between the SPF glass cover edge and
    the OC side document glass CCD output level. If the adjustment is
    normal, the adjusted value is displayed. If abnormal, the error LED
    lights up with the current set value displayed.
    During the error LED is lighted, when [START] key is pressed
    again, execution is performed again. Sharp Gray Scale adjustment level

    turn on during the sensor ON status.
    06 Aging of mirror scanning[Function]
    When [START] key is pressed, the mirror base performs full scan at the speed of the set magni-
    fication ratio.
    During operation, the set magnification ratio is displayed.
    After 3sec, the mirror base performs full scan again. 
    ∗When [START] key is pressed once, the ready lamp remains OFF.
    The mirror home position sensor status is displayed on the Drum replacement required lamp.
    (The lamp is ON when the mirror is in the home position.)
    During aging, the copy lamp is ON.
    [Operation]
    The operation is similar to simulation 1-01.
    2 01 SPF aging operation 
    (Option)[Function]
    When [START] key is pressed, the set magnification ratio is obtained. For the SPF, the single-
    face document transport is performed.
    However, the operating conditions dont matter and the operation is not stopped even in case of
    a jam.
    [Operation]
    The operation is similar to simulation 1-01.
    02 SPF sensor status display 
    (Option)[Function]
    The ON/OFF status of the SPF sensors can be checked with the LED.
    When a sensor is ON, the sensor name is displayed on the LED.
    03 SPF Motor ON 
    (Option)[Function]
    When [START] key is pressed, the motor rotates for 10sec at the speed corresponding to the
    set magnification ratio.
    [Operation]
    The operation is similar to simulation 1-01.

    							MX-B200  SIMULATION, TROUBLE CODES  10 - 3 5 01 Operation panel display 
    check[Function]
    
    When [ENTER/START] key is pressed, the LED on the operation panel lights up in all pixels.
    The status display is as follows:
     After all ON (5 sec)
    7seg panel model: 
    Returns to the sub code input standby (Sub code blinking).
     During LED check mode (All ON)
    7seg panel model: 
    When [1 UNIT UP] key is pressed, the machine goes into the individual lighting mode. 
    When [C] key is pressed, the machine enters the sub code input standby state (sub code 
    blinking).
    When [START] key is pressed, the machine goes into the key input check mode.
    In the individual lighting mode, the LED on the operation panel moves from the top of the left 
    edge to the bottom, then moves to the next right and from the top to the bottom. 
    In this manner, all LED’s are lighted sequentially. (For the 7seg display, the LED’s of three digits 
    are lighted at a time.) After completion of lighting all the LED’s, the machine returns to the all-
    lighting state. It enters the sub code input standby state 5 sec after returning to the all-lighting 
    state. (The cycle of the individual lighting mode is: ON: 300ms, OFF: 20ms)
    
    The status display is as follows:
     7seg display during the key input check mode
    7seg panel model: ---
    Every time a key on the operation panel is pressed, the number of input is added to be 
    displayed on the 7seg display.
    The key which was pressed once is not counted again. 
    When [START] key is pressed, the count is added. The machine goes to the LED lighting check 
    mode (LED all-lighting state) 3sec after that.
    02 Fusing lamp, cooling fan 
    operation check[Function]
    When [OK]/[START] key is pressed, the fusing lamp repeats ON for 500ms and OFF for 500ms
    5 times. During this period, the cooling fan motor rotates.
    03 Copy lamp ON[Function]
    When [START] key is pressed, the copy lamp turns ON for 5sec.
    6 01 Paper feed solenoid ON[Function]
    When [START] key is pressed, the selected paper feed solenoid repeats ON for 500ms and
    OFF for 500ms 20times.
    02 Resist solenoid ON[Function]
    When [START] key is pressed, the resist solenoid repeats ON for 500ms and OFF for 500ms 20
    times.
    7 01 Warm-up display and aging 
    with jam[Function]
    Copying is repeated to make the set quantity of copies.
    When the simulation is executed, warm-up is started and warm-up time is added for every sec-
    ond from 0 and displayed.
    When warm-up is completed, addition is stopped. When [Clear] key is pressed, the ready lamp
    lights up.
    After that, enter the copy quantity with [ ] [ ] key and press [START] key to repeat copying of
    the set quantity (interval 0sec).
    To cancel the simulation, turn off the power or execute a simulation which causes hardware
    reset.
    06 Intermittent aging[Function]
    Copying is repeated to make the set quantity of copies.
    When the simulation is executed, warm-up is performed and the ready lamp is lighted.
    Enter the copy quantity with the [ ] [ ] key and press [START] key, and copying is executed to
    make the set quantity of copies, and the ready state is kept for 3sec, and copying is executed
    again to make the set quantity of copies. These operations are repeated.
    To cancel the simulation, turn off the power or execute a simulation which executes hardware
    reset.
    08 Shift to copy with the 
    warm-up display[Function]
    Enter the simulation code, and warm-up is started and warm-up time is counted for every sec-
    ond from 0 and displayed.
    When [Clear] key is pressed during counting up, 0 is displayed on the display and counting is
    stopped. However, warm-up is continued.
    After completion of warm-up, counting is terminated. (The aging function is removed from simu-
    lation 7-01.) Main
