[9] ADJUSTMENTS 1. Optical section A. Copy magnification ratio adjustment The copy magnification ratio must be adjusted in the main scanning direction and in the sub scanning direction. To adjust, use SIM 48-1. (1) Outline The main scanning (front/rear) direction magnification ratio adjustment 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 scanning (front/rear) direction magnification ratio adjustment automatically. Manual adjustment: The adjustment is made by [Copy quantity] keys (or [Numeric] keys for the AR-M200/M201) operations. (In either of the automatic and manual adjustments, 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 (+) Scale 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. AR-203E/5420/M200/M201 ADJUSTMENTS 9 - 1 5) Calculate the main scanning direction magnification ratio. Main scanning direction magnification ratio = Copy image dimensions X 100 (%) Original dimension (When a 100mm scale is used as the original.) Paper feed direction mm 1/2mm mm 1/2mm 6) Check that the copy magnification ratio is within the specified range. If it is not within the specified range, perform the following 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 selector] key (or [ ] [ ] key for the AR-M200/M201). 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 simulation 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.

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.
