Does anyone know where I can get exploded views of this item?
I'm repairing a broken piece of plastic and need to remove or separate the side piece, pic 1 with circuit card.
There's a screw bottom left, bottom, right, center of circuit card and two tab locks, top left and top right.
The end plate becomes loose but there's something holding it in the middle. I can lift the circuit card off its mount but can't see any more screws.
Do anyone know what's holding the middle in the general area under the circuit card?

I figured out how to remove the end cap plate of the PIU.
There's a screw bottom left, bottom right and two tab locks, upper left and side right.
Remove the screw from the circuit card and disconnect any cables.
It'll take some wiggling but the end plate will come off but make sure the end is upright so two gears don't come popping off.
The reason for doing so was that I had to epoxy the broken end piece and there was a white piece with two ears that need to be put back in place.
The broken piece that was epoxied in held one ear hole and the second was on the base.
See pictures.

There will be no official blow up as these printers were repaired via sub-system replacements, not individual components. Check out You tube, you might find something. It has been years since I had one of those apart and beyond pulling the circuit board to replace it, never went any further. Sorry to not be able to guide you further.

I've searched and searched for exploded views, including YouTube, because it was a shot in the dark that someone might know how to remove the end plate where the circuit card mounts.
I see plenty of places that sell refurbished units (no longer available) so I assumed someone might know how to remove the end plates.
