Charging
The primary component of the charging process is the high voltage power supply. The following provides
information that covers the mechanical transfer of the high voltage through a set of springs to each
subcomponent of the charging process.
Photoconductor unit (charge roll)
The following illustration shows the circuit path that allows high voltage current to flow from the HVPS to the
charge roll contact on the photoconductor unit. It is essential that the contact springs are properly touching to
provide a good flow. If not, print quality problems will occur.
Photoconductor unit (photoconductor drum)
The following illustration shows the circuit path that allows high voltage current to flow from the HVPS to the
photoconductor drum contact on the photoconductor unit. It is essential that the contact springs are properly
touching to provide a good flow. If not, print quality problems will occur.
