Xerox Internal Use Only Phaser 7100 Service Manual 1-57
Toner Supply
The Phaser 7100 uses dry bi-component magnetic toner with the two components: Toner and Carrier.
Other than toner, a small amount of carrier is also present in the Toner Cartridge. To prevent the
degradation of the toner, the toner together with the carrier are supplied into the Developer Housing
Assembly while at the same time removing the used toner from the Developer Housing Assembly.
