Try this one, may be you can get same ideas

InCase that Paper Setting for the Poor Image is "Plain Paper"

1) Target current setting ofdischarge current control

(COPIER>ADJUST>HV-PRI>DIS-TGM/TGC/TGK)<Level2>

The setting value of theapplicable service mode is set to "+2." If not improved, the setting

value is increased by every [+2 ].

2) Adjustment of electrostaticcharge AC current

(COPIER>ADJUST>HV-PRI>OFSTAC-M/OFSTAC-C/OFSTAC-K) <Level1>The setting value of the applicable service mode is set to"+2." The setting value is set to +4,

If not improved.

InCase that Paper Setting for the Poor Image is "Heavy Paper"

1) Target current setting ofdischarge current control (COPIER>ADJUST>HV-PRI>DIS-TGM2/

TGC2/TGK2) <Level2>

The setting value of theapplicable service mode is set to "+2." If not improved, the setting

value is set to +4.

2) Adjustment of electrostaticcharge AC current (COPIER>ADJUST>HV-PRI>OFSTACM2/

OFSTACC2/OFSTACK2)<Level1>

The setting value of theapplicable service mode is set to "+2." The setting value is set to+4,

If not improved.

[Notesabout remedy]

A drum life will be influencedif the 2nd service mode (adjustment of electrostatic charge AC

current) is changed.

For this reason, please do not set the setting value to +4or more at the maximum.

Like this example below ???????????????????

The Improvement Kit for the ITB Assembly was installed to resolved this copy quality issue. Part number FM4-8409-000.

Its 80, the solution was the external secondary transfer roller. Even though it was replaced 2 weeks prior, it was contaminated. Thanks.

That roller is still good pal.
You need to go in service mode and adjust your Transfer voltages, to compensate for the environmental changes (humidity, temp)
