MX-2300/2700 N/G ADJUSTMENTS 6 – 57 If a considerable time has passed after completion of the color bal- ance adjustment (Manual) with SIM 67-25, the color balance of the adjustment pattern at the time of adjustment differs from the color balance of the adjustment pattern printed after a considerable time. Never use such a pattern for the adjustment. The correctness of the service color balance target data can be judges as follows. Select the service color balance target with SIM 67-24 and execute the color valance adjustment (Auto), and check the adjustment result. When the result is unsatisfactory or abnormal, the registered service target data for the color balance adjustment (Auto) may be improper. This may be caused when an improper or abnormal color balance adjustment pattern was used to register the service color balance target data for the color balance adjustment with SIM 67-27. The color balance adjustment pattern used in registration was made and printed by the color balance adjustment (Manual) with SIM 67-25. This procedure may have been executed erroneously. b. Setting procedure (Setting procedure of an optional color balance (gamma) as the service color balance target) 1) Use SIM 67-25 (Printer color balance adjustment (manual adjustment) mode) to print two sheets of the color patch image (adjustment pattern). If the color balance is shifted from the standard, an adjustment is required. If not, an adjustment is not required. When an optional color balance is requested by the user, make an adjustment. 2) Enter the SIM 67-27 mode. 3) Press [SETUP] key. 4) Set the color patch image (adjustment pattern) correctly adjusted and printed in the printer color balance adjustment (Manual adjustment) (SIM 67-25) (ADJ 21C) on the document table. A color patch image (adjustment pattern) printed by another machine can be used. Set the pattern so that the light density side is on the left side. Place 5 sheets of white paper on the color patch image (adjustment pattern). If the color balance could not be adjusted satisfactorily with SIM 67-25 (Color balance adjustment (Manual)), do not exe- cute SIM 67-27 to register the service color balance target data. 5) Press [EXECUTE] key. The color patch image (adjustment pattern) is read.6) Press [REPEAT] key, set the second color patch image (adjustment pattern), and execute the procedure 5) again. The color balance (gamma) target set level of each color (KCMY) can be checked with K/C/M/Y keys. Check that the set level is increased in the sequence of B – O. If there is no variation or variation is reversed, it is judged as abnormal. In case of an abnormality, settle the problem and try again. 7) Press [OK] key. The color balance (gamma) of the color patch image (adjust- ment pattern) used in the procedure 5) is set as the service tar- get. (Procedures to set the service color balance target and the color balance target for the user color balance adjustment to the same color balance as the factory color balance target) This procedure must not be executed when the copy color balance was adjusted with SIM 67-25 to a unique color balance requested by the user and it was registered as the service color balance tar- get with SIM 67-27. * When the factory color balance target is changed with SIM 67- 26, be sure to execute this procedure. 1) Enter the SIM 67-28 mode. 2) Press [EXECUTE] key. 3) Press [YES] key. The service color balance target and the color balance target for the user color balance adjustment are set to the same color bal- ance as the factory color balance target. 21-C Auto color balance adjustment by the user (Copy color balance auto adjustment ENABLE setting and adjustment) a. General In the user program mode, the user can execute the auto color cal- ibration (auto adjustment of the copy color balance and density). This adjustment is to set Enable/Disable of the above user opera- tion with SIM 26-54. NOTE: This setting must be set to ENABLE only when the users understanding on the automatic adjustment of the copy color balance and density and the users operational ability are judged enough to execute the adjustment. When set to ENABLE, give enough explanations on the operating procedures, notes, and operations to the user. This adjustment is required in the following cases. * When a U2 trouble occurs. * When the PCU PWB is replaced. * When the EEPROM on the PCU PWB is replaced.
