OKI b4350 - how to remove cover for repair

[Copy link]

Post time: 2010-1-30 23:32:31 |Show all posts
I've been receiving an error 020 message on my OKI B4350N printer and was told by a local repair company that I need a new logic board.
I would like to buy a cheap OKI 4350 printer for parts on ebay and simply swap out the logic board. I am having difficulty figuring out how to remove the cover to get to the board for repairs.
I found a service manual, on-line, however it did not explicitly state how to remove the cover. Are there screws or clips?
Any help would be appreciated.

Thank you, Mcprinter !
Perfect! I would have never found those two clips on my own.
I made it through the first several steps. Will wait to finish the disassembly until after I actually get the swap board. Should be smooth sailing from here.
Thanks again, for the quick and thorough response.
I apprececiate it!

Remove the small cover at the rear.
Open the top cover. The main body is held on by clips.
The clips are on each side about 2 inches from the front. Use a flatblade screwdriver.
Unplug control panel cable and remove the screw from the silver strip.
Remove 1 screw from the left and 2 on the right of the rear metal frame
Slide it backwards to remove.
The whole black plastic part needs to be removed.
Unplug all cables.
1 screw in each corner, 1 in the middle towards the front, 1 between the motors.
You need to remove the transfer roller. Don't touch the foam part.
Remove the small horse-shoe shaped clip on the left side of the transfer roller by pulling it up. Squeeze the clip on the right and slide the transfer roller left to remove.
Remove the screw uncovered by removing the transfer roller.
The plastic part should lift off now giving access to the boards.
Replacing the board is easy from here.
