28 Transfer shifts with halftone on thick paper under high
humidity
[Symptom]
Under high humidity environment (70%Rh and over) and when thick paper is used, density
change appears on halftone at 2 points (at 225mm and at 380 mm from leading edge).
Leading
edge
Approx. 225mm
Approx. 380mm
[Probable cause]
Separation DC current is improper.
[Solution]
1) With dipswitch setting, enable process adjustment for each tray.
Service mode=> [03 System setting] => [01 Software SW Setting] : Change 01-0 from 0 to
1.
2) For each tray, process adjustment, set the [Separation DC (Front)] and [Separation DC
(Back) optimum value within -20 to -30 so that the density difference is the least visible.
Set these values to
the range -20 to -30.
