1TR-TGM2
Adj M pry trns ATVC tgt crrnt:1/2 speed
Lv.2 Details
To adjust the target current for M-color upon primary transfer ATVC
control at 1/2 speed.
Increase the value when low-voltage mottled image occurs, and
decrease the value when fogging occurs (especially in the 95 mm
portion of the image leading edge).
The setting is reflected at the next primary transfer ATVC control.
Use case
When an image failure due to the primary transfer occurs
Adj/set/operate method 1) Enter the setting value (switch negative/positive by -/+ key) and press
OK key.
2) Execute 1ATVC-EX.

Adj C pry trns ATVC tgt crrnt:1/2 speed
Lv.2 Details
To adjust the target current for C-color upon primary transfer ATVC
control at 1/2 speed.
Increase the value when low-voltage mottled image occurs, and
decrease the value when fogging occurs (especially in the 95 mm
portion of the image leading edge).
The setting is reflected at the next primary transfer ATVC control.

T2TR-LNG
Adj of lead edge weak bias apply length
Lv.2 Details
To adjust the length (distance from the leading edge of paper) to apply
leading edge weak bias.
Increase the value when white spots occur in a broad area of the
leading edge of paper.
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.

Adj of trail edge weak bias apply length
Lv.2 Details
To adjust the length (distance from the trailing edge of paper) to apply
trailing edge weak bias.
Increase the value when white spots occur in a broad area of the trailing
edge of paper.
Use case
When an image failure (white spots at the trailing 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
Adj pry trns ATVC ctrl exe intvl: 1/2SPD
Lv.2 Details
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.
