Theory of Operation 2

Introduction

This chapter explains the mechanical and electrical theory of operation of the ENCAD NovaJet 500/630/700 Series Color Inkjet printers.

The NovaJet 500/630/700 Series is a PowerPC 33MHz microprocessor- based digital printer that receives plotting instructions from a host computer through either the RS-422 serial interface or the Centronics parallel interface.

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

The NovaJet 500/630/700 Series printers consist of three mechanical assemblies:

1.Paper (Media) Axis Drive

2.Carriage Axis Drive

3.Media Feed and Take-Up System

(Mechanical Take-Up system is optional on the 500 & 630 printers.)

and four main electrical assemblies:

1.MPCB (Main Printed Circuit Board)

2.Carriage Assembly

3.Control Panel

4.Power Supply
