System Overview
The Phaser 8860 in either the printer (8860) or multifunction (8860MFP) version uses a Print-
head and new ink formulation to produce color or black and white output. With the exception of
the DADF, Scanner, Exit Module, Ink Loader, covers, and some electronics, the two models are
essentialy the same. For this overview, the 8860MFP is divided into two main components:
Image Input Terminal (IIT - Document Feeder/Scanner) and Image Output Terminal (IOT -
Print Engine). IOT descriptions also apply to the 8860.
