Ver. 1.1
To generate a color image, the OPC drum suitably rotates to the image length, one for each of the primary
colors and for the black color. During each successive pass, the laser exposes the portions of OPC drum
that corresponds to the primary color’s component of the image. Toner is attracted onto the laser-exposed
portions of the OPC drum.
As each color layer is developed on each OPC drum, they are transferred to the Intermediate Transfer Belt
until all four color layers eventually reside one on top of the other on the Intermediate Transfer Belt.
At this point, a sheet of paper is advanced under the Intermediate Transfer Belt and the toner is transferred
to the sheet of paper. The paper advances to the Fuser, where heat and pressure permanently bond
the toner to the paper. From the Fuser, the paper is driven to the Output Tray.
A cleaning blade scrapes residual toner from the OPC drum before the next primary color toner is applied to
the OPC drum. This prevents contamination of the next color layer. The cleaning blade is in constant
contact with the OPC drum.
An Intermediate Transfer Belt cleaner scrapes residual toner from the Intermediate Transfer Belt. This
prevents “ghosting “ of the next print.

Charging
The charging roller, comes in contact with the OPC drum surface and charges it to approximately DC-480
volts + AC voltage, and ensures a uniform negative potential of approximately -430 volts on the OPC drum
surface by the charging roller, depending on the selected printing quality (
Std
: 600 dpi, or
Enhanced
: 1,200
dpi), and ambient temperature.
