TR-DUP7 Set PPside for PPallotted volt adj: set7
Lv.2 Details To set the paper side for setting 7.
Setting 7 is the condition combination of environment, paper type
(paper weight) and feeding side that are set at TR-ENV7, TR-PPR7,
TR-DUP7. When this condition is true, paper allotted voltage that is
set at 2TR-TGT7 is applied to the secondary transfer inner roller.
Use case When an image failure that differs on 1st and 2nd side occurs (mottled
image/density loss due to excessive transfer/toner splash on solid
image).
Adj/set/operate method Enter the setting value and press OK key.
Display/adj/set range 1 to 4
1: Host 1st side, 2: Host 2nd side, 3: Deck 1st site, 4: Deck 2nd side
Default value 1

TR-DUP8 Set PPside for PPallotted volt adj: set8
Lv.2 Details To set the paper side for setting 8.
Setting 8 is the condition combination of environment, paper type
(paper weight) and feeding side that are set at TR-ENV8, TR-PPR8,
TR-DUP8. When this condition is true, paper allotted voltage that is
set at 2TR-TGT8 is applied to the secondary transfer inner roller.
Use case When an image failure that differs on 1st and 2nd side occurs (mottled
image/density loss due to excessive transfer/toner splash on solid
image).
Adj/set/operate method Enter the setting value and press OK key.
Display/adj/set range 1 to 4
1: Host 1st side, 2: Host 2nd side, 3: Deck 1st site, 4: Deck 2nd side
Default value 1

2EL Set of sec trans static eliminator bias
Lv.2 Details To adjust the application voltage of the secondary transfer eliminator
to improve the static eliminator trace or separation failure.
As the value is increased, static eliminator trace and separation
failure will be improved; however, if the value is increased too much,
static eliminator trace occur again. Adjust the value by 100 V and
gradually use the smaller scale to get the optimum point.
As the value is increased by 1, the voltage is increased by 1 V.
Use case When the image failure due to the secondary transfer static
eliminator occurs (related to the static eliminator trace, separation
failure)
Caution If the value is increased too much, static eliminator trace occurs
again.
Display/adj/set range -4000 to 0
Unit 1 V
Appropriate target value -3000 to -2000

1TR-STS1 Ajd of prmry trns sheet interval current
Lv.2 Details To adjust the offset value of sheet interval target current of primary
transfer.
Increase the value 1 by 1 until image failure is fixed.
As the value is increased by 1, the current is increased by 5 uA.
Use case When the image failure due to primary transfer occurs (related to the
drum memory)
Display/adj/set range -10 to 10

Appropriate target value 0
Default value 0
1TR-TGT1 Adj of prmry trnsfer target current(Ev0)
Lv.2 Details To set the target current that is applied to the primary transfer roller
under the condition of absolute moisture ratio 0.63 g/m
When mottled image occurs, increase the current and when water-
drop mark occurs, decrease the current.
As the value is increased by 1, the current is increased by 5 uA.
+: Increase
-: Decrease
Use case When the image failure due to primary transfer occurs (related to
mottled image, water-drop mark)
Adj/set/operate method Enter the setting value and press OK key.
Caution Increase/decrease the value 1 by 1 and check the symptom each
time.
Display/adj/set range -10 to 10
Unit 5 uA
Default value 0
1TR-TGT2 Adj of prmry trnsfer target current(Ev1)
Lv.2 Details To set the target current that is applied to the primary transfer roller
under the condition of absolute moisture ratio from 0.64 to 1.72 g/m
When mottled image occurs, increase the current and when water-
drop mark occurs, decrease the current.
As the value is increased by 1, the current is increased by 5 uA.
+: Increase
-: Decrease
Use case When the image failure due to primary transfer occurs (related to
mottled image, water-drop mark)
Adj/set/operate method Enter the setting value and press OK key.
Caution Increase/decrease the value 1 by 1 and check the symptom each
time.
