2 Adj C pry trns ATVC tgt crrnt:1/1 speed
To adjust the target current for C-color upon primary transfer ATVC control at 1/1 speed. Increase
the value when low-voltage mottled image occurs, and decrease the value when fogging occurs
(especially in the 94 mm portion of the image leading edge).
The setting is reflected at the next primary transfer ATVC control.
When an image failure due to the primary transfer occurs
1) Enter the setting value (switch negative/positive by -/+ key) and press OK key.
2) Execute 1ATVC-EX.

1 Uniform adj sec trn ATVC ppr allot voltg
To uniformly adjust paper allotted voltage in secondary transfer ATVC control regardless of paper
type, 1st/2nd side or environment.
When transfer failure occurs on an image, increase/decrease the value in the -30 to 30 (-900 to
900 V) range in increments of 10 (300 V).
When white dots occur on an image, increase/decrease the value in the -100 to -10 (-3000 to -300
V) range in increments of 10 (300 V). When the value is decreased too much, transfer failure
occurs.
When similar image failures occur regardless of the conditions
Enter the setting value (switch negative/positive by -/+ key) and press OK key.
If TR-VL1 to VL16 are set, each paper allotted voltage is the value to which the setting value is
added.
