3.2 DISASSEMBLY/ASSEMBLY PROCEDURES
This section contains the disassembly procedures. Only the removal procedures are explained
here. Reverse the procedure for the installation.
At the bottom of each procedure is a listing of Okidata part numbers, item descriptions, and
cross-references to Appendix B. Items included in the Recommended Spare Parts List are
designated RSPL. N/A will appear where a part number is not available.
We have listed disassembly procedures for major components of the Doc-It 3000/4000.
Remember that Okidata does NOT recommend disassembling a unit which is functioning
normally. If you decide to perform disassembly during this training, we recommend 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
a Doc-It 3000/4000.
On the following pages is a flowchart of disassembly procedures and an index for the flowchart.
Follow these steps when disassembling the Doc-It 3000/4000.
1. Identify the item you need to replace.
2. Determine which procedure contains the instructions for this item. Refer to the Table of
Contents or Appendix B.
3. Use the Flowchart Index to find the page of the flowchart which contains the procedure
you will use.
4. Go to the appropriate page of the flowchart.
5. Locate the box of the procedure you will use.
6. Plot your order of disassembly, moving from the procedure you identified and ending
with START. We recommend that you write the procedure numbers on another sheet of
paper.
7. Perform the disassembly procedures you have plotted, beginning with START and
ending with the procedure for the part you wish to replace.
For example:
1. You have determined that the engine controller board (SPPY) needs to be replaced.
2. The disassembly procedure for the engine controller board is 3.2.29.
3. The flowchart index tells us that this procedure is on page two.
4. Go to page two of the flowchart.
5. Locate the box for the engine controller board, 3.2.29.
6. Write 3.2.29 on another sheet of paper.
Follow the flow line back to the box for the main controller board (SPSX), 3.2.23.
Write 3.2.23 on your other sheet of paper.
Follow the flow line back to the box for upper cover, 3.2.06.
Write 3.2.06 on your other sheet of paper.
