3.2. PRINTER 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
aregiven at theend of thedescription of each procedure. Be sure tofollow theinstructions in these notes.
•Before disassembling any part of the printer, note the warnings in Section 3.1.
•Before beginning to disassemble the printer, remove the paper and the ink ribbon.
Also disconnect the interface cable.
•Whenever the printer is repaired, wipe the surface of the paper width (PW) sensor assembly
with a soft cloth, and keep it clean to avoid abnormal operation. Ifthe surface is dirty from
any adhering material, sensor sensitivity goes down and operation is not correct.

them as necessary. The flowchart below shows the orderyou need to use to disassemble the
