Adj Bk-color charging AC voltage: L-SPD
To adjust the offset of the charging AC voltage for Bk-color at low process speed.
The setting is applied to paper which paper weight is 129 g/m2 or more and coated paper.
As the value is changed by 1, the voltage is changed by 20 Vpp.
Decrease the value when image smear occurs, and increase the value when an image failure
(sand-like image) occurs.
- When image smear occurs
- When an image failure (sand-like image) occurs
Enter the setting value (switch negative/positive by -/+ key) and press OK key.
Use OFSTACK2 only when an image failure is not alleviated with DIS-TGK2. In such case, be sure
