1TR-TGM
Adjusting target current offset of primary transfer ATVC (M)
Adjustment range: -5 to 5 (unit: 0.5 uA) (default: 0)
It is enabled when COPIER>OPTION>BODY>PTATVCSW = 1 (primary ATVC control is enabled).
Change a setting value when any of the following faulty images occurs.
- Mottle marks/Mark of the auxiliary brush due to remaining transfer toner (when color density of the brush mark is
high)/Transfer ghost: Primary transfer current is low. -> Change a setting value to the '+' direction.
- Fogging due to re-transfer/Mark of the auxiliary brush due to remaining re-transfer toner (when color density of the
former station is higher than that of the brush mark): Primary transfer current is high -> Change a setting value to the
'-' direction.
