4.2 Disassembly and Assembly

This section describes procedures for disassembling and assembling the
main components of the printer. When the procedure for installing a
component is simply the reverse of removing the component, this chapter
does not describe the assembly procedure. If necessary, special notes on
assembling or adjusting a component are given at the end of the
description of each procedure. Be sure to follow the instructions in these
notes.
The exploded diagrams in the appendix show how the components fit
together. Refer to them as necessary.

Before you disassemble the printer, follow the

Whenever you repair the printer, wipe the
surface of the paper width (PW) sensor
assembly with a soft cloth, and keep it clean to
avoid abnormal operation. If the surface is dirty
because of any adhering material, sensor
sensitivity decreases and printer operation is
impaired.
