2TR-TGT8 Sec trns indiv set target currnt: set 8
Lv.2 Details To adjust the target current of secondary transfer for setting 8.
Setting 8 is the combination condition of environment, paper type
(paper weight), color mode and feed side that are set in TR-ENV8,
TR-PPR8, TR-CLR8 and TR-DUP8. When this condition is satisfied,
the target current that is set here is applied to the Secondary
Transfer Outer Roller.
When low-voltage mottled image or toner scattering on solid image
occurs, increase the current.
When high-voltage mottled image or density loss due to excessive
transfer occurs, decrease the current.
As the value is incremented by 1, the current changes by 2 uA.
+: 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, and then press OK key.
Caution Increase/decrease the value by 1 while checking the symptom each
time.

Setting 1 is the combination condition of environment, paper type
(paper weight), color mode and feed side that are set in TR-ENV1,
TR-PPR1, TR-CLR1 and TR-DUP1. When this condition is satisfied,
the paper allotted voltage that is set here is applied to the Secondary
Transfer Outer Roller.
As the value is incremented by 1, the voltage changes by 100V.
+: Increase
-: Decrease
Use case When an image failure that differs due to the paper type occurs
(mottled image/density loss due to excessive transfer/toner scattering
on solid image)
Adj/set/operate method Enter the setting value, and then press OK key.

TR-PPR3, TR-CLR3 and TR-DUP3. When this condition is satisfied,
the paper allotted voltage that is set here is applied to the Secondary
