6. Increase the transfer current for all stations in the Advanced Settings as follows.
-No 18: Image Transfer Current: FC: Black 55uA 70uA
-No 19: Image Transfer Current: FC: Cyan 50uA 70uA
-No 20: Image Transfer Current: FC: Magenta 50uA 70uA
-No 21: Image Transfer Current: FC: Yellow 55uA 70uA
Note the possible side effect “a” when applying the above setting.
If the results are accepted by the customer, complete the procedure.
If the results are unaccepted by the customer and/or exhibits No.2 Shock-jitter at OPC, do
the following step.
7. Set the transfer current values back to the default for all 4 stations.
8. Modify the Advanced Settings “No 14: Process Speed Setting” from High Low, to
reduce the amount of shock generated at the PTR nip.
Note the possible side effect “b” when applying the above setting.
If the results are accepted by the customer, complete the procedure.
If the results are unaccepted by the customer, do the following step.
9. Set the process speed back to “High” in Advanced Settings “No 14: Process Speed
Setting”.
10. In Advanced Settings, adjust “No 37: Paper Feed Interval Setting” to move the band
to a position less noticeable on the printouts.
Note the possible side effects “c” and “d” when applying the above setting.
Increase the value in 0.1 increments to move the banding/shock-jitter toward the leading
edge. Banding/shock-jitter exhibited on 2
nd
page and on will move 46mm toward the
leading edge, and those exhibited on 3
rd
page and on will move 92mm toward the leading
edge.
For more detail, see the appendix.
Make sure to retrieve the default value in the Advanced Settings if no improvements are
confirmed.
Side effects
a) Possible toner scattering of poor transfer
b) Productivity will reduce to approximately 78%
c) Productivity will reduce as follows:
“No 37: Paper Feed Interval Setting”
0.1 Approx 90% productivity
0.2 Approx 85% productivity
0.3 Approx 80% productivity
d) Possible occurrences of “Blister”
