TR-VL16 2 Sec trn indiv set ppr allot voltg:set 16
Detail To adjust the paper allotted voltage of secondary transfer for setting 16.
Setting 16 is the combination condition of environment, paper type (paper weight), color mode/
feed side that are set in TR-ENV16, TR-PPR16 and TR-DUP16. When this condition is satisfied,
the paper allotted voltage adjusted here is applied at the time of secondary transfer. If the setting
of 2TR-OFF is made, the setting voltage is added to the paper allotted voltage.
Increase the value when low-voltage mottled image or toner scattering on solid image occurs.
Decrease the value when high-voltage mottled image or density loss due to excessive transfer
occurs.
As the value is changed by 1, the voltage is changed by 30 V.
+: Increase
-: Decrease
Use Case When an image failure occurs on all paper types (mottled image, density loss due to excessive
transfer, toner scattering on solid image, etc.)
Adj/Set/Operate Method Enter the setting value (switch negative/positive by -/+ key) and press OK key.
Caution Increase/decrease the value by 1 at a time while checking the symptom.
Display/Adj/Set Range -128 to 127

Supplement/Memo Up to 16 combination patterns can be set in TR-VL1 to 16 (setting 1 to 16). When there is more
than one setting where all conditions (environment, paper type and color mode/feed side) are the
same, the setting with a smaller setting number is applied.

1TR-TGK2 2 Adj Bk pry trns ATVC tgt crrnt:1/2 speed
Detail To adjust the target current for Bk-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.
