Chapter 3 Maintenance & Disassembly

 

3.2 DISASSEMBLY/ASSEMBLY PROCEDURES

General Information

This section contains the printer disassembly procedures. Only the removal procedures are 
explained. Reverse the procedure for the installation.

This Service Handbook lists the disassembly procedures for major components of the unit. 
Okidata does NOT recommend disassembling a unit which is operating normally. If you decide to 
perform disassembly during this training, Okidata recommends that you perform only

 

the 

disassembly procedures for RSPL items. All other procedures are provided to assist you in 
identifying parts. It is not likely that you will perform these procedures while servicing the product.

Read all notes, cautions, and warnings. They contain important information regarding 
assembly/disassembly.
