Problem Description
Cause Description
Action to Resolve
Horizontal Thick
Band(s) for a
Particular Color
(continue..)
1. Unstable Charging
Bias
2. Unstable Transfer
Bias
(continue..)
1.3) If the ITB grounding is OK, check the THV bias. [TM #107-
0000~0009]
- If there is any wrong value, change the value [TM #107-
0000~0009],
- If the THV value is defective [EDC #107-0000~0005],
replace the HVPS.
1.4) Check the Transfer Bias Harness.
1.5) If it is OK, check the Charging Bias Harness.
1.6) If it is OK, replace the Imaging unit.
1.7) If the problem persists, replace the HVPS.
[2. Unstable Transfer Bias]
2.1) Check and confirm the transfer bias [TM #107-0000~0009].
If there is any wrong value, change the value [TM #107-
0000~0009].
2.2) If the THV value is defective [EDC #107-0000~0005],
replace the HVPS.
2.3) Check the transfer bias noise [EDC #107-0000~0005].
If there is a noise, check the ITB grounding.
2.4) If the grounding is OK, check the transfer bias connection.
2.5) If the transfer bias harness is connected properly, replace
the ITB.
2.6) If the problem persists, replace the HVPS

1. High Transfer
Voltage
2. Low Image Density
[1. High Transfer Voltage]
1.1) Check and confirm the THV bias[TM #107-0000~0009].
If there is any wrong value, change the value [TM #107-
0000~0009].
1.2) If the THV value is defective [EDC #107-0000~0005], check
the T1 roller contact conditions.
1.3) Check the T1 Bias Harness.
1.4) Check the ITB grounding. If it is defective, replace the ITB.
1.5) If the problem persists, replace the HVPS
[2. Low Image Density]
2.1) Check the T/C control value [TM #111-0006~0017]. If there
is any wrong value, change the value.
2.2) Check that the density is increasing or not. [EDC #117-
0000]
2.3) If the density is not increasing, check the CTD density [EDC
#117-0001]. And increase the color density until proper
level on Custom Color Setting.
2.4) If you can't increase the density on Custom Color, change
the T/C control value to increae the density [TM #111-
0006~0017].
