Removal of DX4 manifold screw? Help! -- 1/2 way through manifold replacement!)

[Jumpshoutmedia]

Is there a trick to removing the 2 screws that hold the print head and plastic manifold together? (see photo)

I broke one of the nipples so I bought a replacement manifold and I'm trying to swap it out, but neither of the two tiny phillips screws will BUDGE!

I tried every size phillips driver that I own, I've even tried using a flat blade that was wide enough to fit in the entire screw head, but when I went to unscrew it, the screwdriver blade actually bend/twisted!

I'm afraid to try any harder for fear of breaking something or stripping out the tiny head on this screw causing the entire head to be junk!! PLEASE.. any advise would be GREATLY appreciated!

PS, do I need to remove the white rubber looking stuff that's covering the hex shaped nut on the other side of the manifold? I didn't want to pluck that stuff out to see if there was a nut that could be removed because it looks important.

Thanks!

I have never had an issue, did one today.
I usually remove the brown base first.
You can remove the white rubber stuff, there is a nut under that, put a drop of cleaning solution from the nut side.
You may get lucky.

You absolutely must remove the printhead from the brown head adapter plate. It is physically impossible to remove the manifold screws without doing so. You might need to remove the nut with the white RTV from the old manifold if the replacement manifold doesn't have any. The best way to remove them from the old manifold after you have removed the manifold from the head is to put one of the screws into the nut from the bottom and push the nut out by putting pressure on the screw. No need to put cleaning solution on it, as the RTV will help keep the nut in place while installing it in the new manifold.
