6.8.3 LIST OF PROCESS CONTROL ACRONYMS

The potential control phase of process control involves many adjustments. Here is list of
acronyms used in the descriptions of process control adjustments.
Acronym
Cdc Charge dc bias
Vb Development charge bias
Vb*1 Development charge bias after Vr (residual potential) adjustment
Vd Drum potential after the drum is charged by the charge roller.
Vd*1 Drum potential after Vr (residual potential) adjustment
The electrical potential of the drum after a fixed dc bias (dc –700V) is
Vdhome
applied by the drum charge roller.
Development potential (Vb – Vpl). This is the ability to attract toner to the
Vdp
drum.
Development start voltage (checks the developer at the beginning of
Vk
process control to determine whether it has deteriorated)
Light potential. Development potential of areas on the drum exposed by the
Vl
laser diodes. Maximum laser power has been applied to the diodes.
Electrical potential after laser exposure, with 24/63 of maximum laser power
Vpl
(power is controlled with PWM).
1
Vpl* Electrical potential (Vpl) after Vr (residual potential) adjustment
Vpp Charge ac bias.
Vr Residual potential
Vsg after checking the bare surface of the ITB by the diffused reflection
Vsg_dif
sensor.
Vsg ID sensor output after reading bare surface of the ITB
