Does anyone have an HP-46 printer for parts?

I'm quite tired of this stuff and almost planning to throw everything away. There must be something not so obvious I am missing, but I am stuck now.
I thought I had found a way to do it, but something is still missing.

Did you change the main (large) filter capacitor? Any ripple on the DC supply line to the printer will make it act as if it's not aligned. This is a common problem.
