Adjustment method
After monitoring is performed to the bias value by DISPLAY using this mode. Setting range: -4000 to 0 (Unit: V) [Factory setting value / Value after RAM clear: 0] 1TR-STS1 Offset value of the target current for the primary transfer paper interval (at constant speed) 2 Setting range: -10 to 10 (Unit: 5.0µA) [Factory setting value / Value after RAM clear: 0] 1TR-STS3 Offset value of the target current for the primary transfer paper interval (at 1/3 speed) 2 Setting range: -10 to 10 (Unit: 5.0µA) [Factory setting value / Value after RAM clear: 0] PRE-TR-Y/M/C Adjust the current of the pre-transfer charging assembly. (Y/M/C) 2 Set the current offset value (Y/M/C) of the pre-transfer charging assembly. This is not used for this machine. POSTSW-Y/M/C/K ON/OFF switch for the Y/M/C/K pre-transfer charging assembly 2 Set validity or invalidity of Y/M/C/K color for the pre-transfer charging assembly. Setting value 0: Invalid, 1: Valid [Factory setting value / Value after RAM clear: Y/M/C:0, K:1] 1TR-TGL1 Offset adjustment of the target electric current at the primary transfer ATVC (single L color) 2 Setting range: -10 to 10 Unit: µA) [Factory setting value / Value after the execution of RAM Clear: 0] 1TR-TGL5 Offset adjustment of the target electric current at the primary transfer ATVC (clear color when using 5 colors) 2 Adjustment range: -10 to 10 Unit: 1.0µA) [Factory setting value / Value after the execution of RAM Clear: 0] COPIER > ADJUST > FEED-ADJ Subheading Contents Level REGIST Adjust the timing of turning ON the registration roller clutch. Adjustment method - When you increase the value by 1, the image moves toward the lead edge of the paper by 0.1mm. - When you executed 'RAM clear' for the DC controller PCB or replaced the DC controller PCB, enter the value indicated in the service label. 1 Adjustment range: -50 to 50 (Unit: 0.1mm) [Factory setting value / Value after RAM clear: 0] ADJ-REFE Adjust the horizontal registration for double sided copy. (for factory use) Adjustment method When you increase the value, the second side image moves to the rear side. (When you increase the value by 1, the image moves by 0.1mm.) 1 Adjustment range: -100 to 100 [Factory setting value / Value after RAM clear: 0] BLK-SML2 Adjust the right and left margins on the second side of a small-size sheet. When you increase the value, the left and right margins on the second side become longer. (When you increase the value by 1, the margins increase by 0.1mm.) 1 Adjustment range: -50 to 50 (Unit: 0.1mm) [Factory setting value / Value after RAM clear: -15] RVS-FD1 Adjust the reverse point. 2 Adjustment range: -10 to +10 (Unit: 1mm) [Factory setting value / Value after RAM clear: 0] RVS-DUP Adjust the reverse point for double sided copy. 2 Adjustment range: -10 to 10 [Factory setting value / Value after RAM clear: 0] LOOP-T2 Adjust the registration loop volume when feeding thick paper. Adjustment method When you decrease the setting value (loop volume of the registration roller), a noise is reduced. However, when you decrease the loop volume excessively, the margin size may change or it may cause a skew. 2 Adjustment range: -10 to +10 (mm) [Factory setting value / Value after RAM clear: 0] REG-SPD Make a fine adjustment of the registration motor speed at constant speed. Change the registration speed at constant speed in the range of + or - 10 scales against the default value. 2 Setting range: -10 to 10 Standard value: 0 REG-SPD2 Make a fine adjustment of the registration motor speed at 1/3 speed. Change the registration speed at 1/3 speed in the range of + or - 10 scales against the default value. 2 Setting range: -10 to 10 Standard value: 0 COPIER > ADJUST > HV-TR Subheading Contents Level
