MX-B200 ADJUSTMENTS 9 - 1 [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. b.

MX-B200 ADJUSTMENTS 9 - 3 2) Execute SIM 50-01 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. 5mm 10mm (Example) Distance between paper lead edge and image: H = 5mm Image loss: R = 3mm B4 or 8 1/2″ × 14″ paper A4 size rear edge Paper rear edge Void amount (Standard value: 2 - 3mm) Scale image Document guide Center Copy paper (A4 or 8 1/2″ × 11″) (Copy A) (Copy B)2.0mm or less 2.0mm or less Copy image Copy paper folding line Copy image Copy paper folding line Shift Shift (Paper feed direction)
