Introduction

This chapter explains the mechanical and electrical theory of opera- tion of the ENCAD Croma24 D-Size Color Inkjet printer.

The Croma24 is a MC68322 microprocessor-based digital printer that receives plotting instructions from a host computer through either the RS-422 serial interface or the Centronics parallel inter- face.

Figure 2-1 illustrates the major functional areas of the printer.

The Croma24 printer consists of two mechanical drives:

1.Paper (Media) Axis Drive

2.Carrier Axis Drive

and three main electrical assemblies:

1.MPCB (Main Printed Circuit Board)

2.Carrier Assembly

3.Power Supply
