Theory of Operation
Print Process
The Phaser 7500 uses dry bi-component magnetic toner with the 2 components:
toner and carrier.
Other than toner, a small amount of carrier is also present in the Toner Cartridge.
To prevent the degradation of Developing Beads, the "Trickle Development
Method" is used. This involves supplying the toner together with the carrier into
the Developer Housing Assembly while at the same time removing the used
Developing Beads from the Developer Housing Assembly.
