Disassembly and Assembly LQ-2070 Service Manual 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 are given at the end of the description of each procedure. Be sure to follow the instructions in these notes. CAUTION • 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. If the surface is dirty from any adhering material, sensor sensitivity goes down and operation is not correct. • Be careful operating the release lever. Frequent operation of the release lever back and forth without the upper housing cover may cause damage to the lever or dislocation of the engagement. Note: Exploded diagrams in the appendix show you how the components fit together. Refer to them as necessary. The flowchart below shows the order you need to use to disassemble the printer.
