2ROT-CC Current adj at scndry trns cndctv idling
Lv.2 Details When resistance value of the secondary transfer roller is too low,
there will be white spot at the leading edge on image with thick
paper. Although this resistance value is increased by executing idle
rotation while applying bias voltage to the secondary transfer roller,
increasing the target current value can increase the resistance value
in a short time
ATVC control is executed at the initial stage of idle rotation if
changing the value.
1 increment of the value increases the current by 5.0 micro A.
Use case Increase the value in the case of white spot (dot) on HT image.
Adj/set/operate method Enter the setting value, and then press OK key.
Display/adj/set range -10 to 10
Unit 5.0 micro A
Default value 0

2RV-MODE Set sec transfer bias at paper interval
Lv.2 Details To set the secondary transfer reverse bias applied at paper interval.
To prevent the back side of the sheet soiled by the soiled Secondary
Transfer Outer Roller, positive and reverse secondary transfer bias
is alternately applied to the Secondary Transfer Inner Roller at paper
interval.
By setting 1 or 2 when the 2nd side is soiled, the secondary transfer
reverser bias becomes OFF or 0V is applied.
Use case When the 2nd side is soiled
Adj/set/operate method Enter the setting value, and then press OK key.

DRM-IDL Set first power-on idle rotation time
Lv.2 Details To set idle rotation time at first power-on.
By performing idle rotation of the Photosensitive Drum, the fusion of
toner with the Drum can be prevented.
Use case When image smear or low density occurs right after power-on
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF and then ON the main power supply.
Display/adj/set range 0 to 4
0: OFF (Not idle-rotated), 1: 30 seconds (at high humidity only),
2: 120 seconds (at high humidity only),
3: 30 seconds (in all environments),
4: 120 seconds (in all environments)
Default value 0
DV-RT-LG Adj of WH band eject time at pre-rotatin
Lv.1 Details Adjust the time to execute white band discharging at multiple initial
rotations.
When the value is incremented/decremented by 1, time increases/
decreases by 1 minute. (Initial value 0: 7 minutes)
+: Increase
-: Decrease
Use case When a user gives priority on startup time
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF and then ON the main power supply.
Caution When time is set to be shorter, an image failure, etc. may occur due
to lack of electric potential in toner.
Display/adj/set range -7 to 7
