Nice to join in now and again.
No amount of cleaning helped me - but a spare Poly Motor cleared it...

To remove the PH unit, you must first remove power supply board and small board on the bottom with two flat cables. That's a PH unit control board.

So, you probably "solve" the problem by dissconnecting and connectin flat cables into it.

No dirt can cause the vertical lines. Dirt in PH unit can only cause faint images. This is an electrical issue.
This PH control board is cheap, better hope it is the cause rather than MFP board.

Well, that explains it if it's electrical. All I know is it needed the polygon mirrors cleaned and after I put it all back together, it worked and still is working. So, yes, might have been re-securing the cables that fixed the lines issue.

BTW, this machine has 579K on it.

I'm still in the dark ages here.
Are the PH serviceable now on the 8 series?
Or are you just doing it cause you know how to?

No, it should not be opened according to the service instructions,
but if the problem can be solved only by cleaning the poligon mirrors, why not try,
Write unit is not very cheap so worth trying.

Definitely not usual but with so many machines in the field it happens.

Just to add my experience....it's electrical noise/sparking in power connections for most of the time for me.....faded images are definitely dirty laser windows but never had to clean inside of the laser... confirm your electrical mains for any loose connections..
