Chapter 4: Removing and Replacing Components
Introduction
This chapter covers removal and reinstallation of selected field replaceable compo-
nents and assemblies of your printer.
Unplug the printer and remove paper and ribbon for all procedures in this chapter.
Any time you remove a component that is involved in some aspect of the printing

Unless otherwise noted, reinstallation of components is in the reverse order of installa-
tion or removal.
