Developing process
In the developing process, an electrostatic latent image attracts printer toner and becomes visible on the
OPC belt.
There are four toner cartridges. See “Printer theory of operation” on page 1-14 for toner cartridges
location. The toner cartridges are located in the printer from top to bottom in the order of black, yellow,
magenta, and cyan.
1. Toner adheres to the developer roller.
The developer roller makes contact with the surface of the OPC belt which begins the developing
process.
2. The developer roller has been biased to -DBV(V) potential.
The first illustration shows the relationship between the toner, the
-Vo(V) at the non-exposed area of the OPC belt and the -VR(V) at the exposed area of the OPC belt.
