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 1-19 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.
