Reading Definition Abnormal Reading
Vd
Charge bias (Cdc). This is the output of
the potential sensor after –700V is
applied to the drum.
Range: -500 to –700 V
If the reading is out of range:
Potential sensor damaged
Charge unit malfunction
Charge power pack
malfunction
Vr
Residual voltage. This is the output of
the potential sensor after the LD fires at
full power.
Normal: -200 V
If above –200V:
Drum worn
Toner shield glass dirty
Potential sensor out of position
Voffset
This is the reading of the potential
sensor with no charge applied to the
drum.
Normal: 0 ±10V
If reading is out of range:
Potential sensor dirty
Potential sensor out of position
