T2TR-LNG 2 Adj of lead edge weak bias apply length
Detail To adjust the length (distance from the leading edge of paper) to apply leading edge weak bias.

Use Case When an image failure (white spots at the leading edge) occurs
Adj/Set/Operate Method Enter the setting value (switch negative/positive by -/+ key) and press OK key.
Caution Use this item only when an image failure occurs.

1ATVCTMG 2 Adj pry trns ATVC ctrl exe intvl: 1/2SPD
Detail To adjust the intervals (the number of sheets) to execute primary transfer ATVC control at 1/2
speed.
Decrease the value if the condition of image failure occurrence caused by primary transfer is as
follows:
- It does not occur at 1/1 speed, but occurs at 1/2 speed.
- It is alleviated by executing primary transfer ATVC control.
- It is temporarily alleviated when continuing output, but it occurs again.
These indicate that primary transfer ATVC control is not executed at 1/2 speed.
Image failure can be alleviated by increasing the frequency to execute primary transfer ATVC
control, but productivity at 1/2 speed decreases.
Use Case When an image failure or blocky image at 50 mm intervals occurs at 1/2 speed
Adj/Set/Operate Method Enter the setting value, and then press OK key.
Caution As the value is smaller, productivity at 1/2 speed decreases. As the value is increased, productivity
is increased, but image failure may occur.
