Potential sensor calibration error 2
C
During drum potential sensor calibration, the drum potential sensor output
voltage does not meet specification when test voltages (–100V, –800V) are
applied to the drum.

Potential sensor defective
Potential sensor harness disconnected
Potential sensor connector defective or disconnected

Potential sensor calibration error 3
C
During drum potential sensor calibration when adjusting the drum potential
(VD), the drum potential sensor detects VD higher than VG (grid voltage).
-or-
When adjusting VD (drum surface potential of black areas after exposure),
even after 5 adjustments of VG (charge corona grid potential), VD could not
be set in the target range (–800±10 + VL + 130V)

Potential sensor calibration error 4
314 C
During drum potential sensor calibration when adjusting the drum potential
(VH) for LD power adjustment, the first time the VH pattern is made, the
drum potential sensor detects that VH is more than 500V:
VH > –500 + VL + 130 V
