2TR-TGT6 Sec trns indiv set target currnt: set 6
Lv.2 Details To adjust the target current of secondary transfer for setting 6.
Setting 6 is the combination condition of environment, paper type
(paper weight), color mode and feed side that are set in TR-ENV6,
TR-PPR6, TR-CLR6 and TR-DUP6. 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.)
