Once this machine started doing it (only on color), it never stopped the black lines until I removed the P/H and cleaned the polygon mirrors, so I'm hoping that was the issue and not P/H board. Time will tell.Originally Posted by REGSIS

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.
I have had those lines twice. First time machine was close to 2 million counter so we swapped machine. Second one I did swap board prior whole PH unit that didn't work. At the end I leave original machine's board and swap PH unit with another used(but good) one PH unit that fixed it.

Our dealership is primarily Toshiba, but also Kyocera, Konica Minolta, Lexmark, Kip, HP, Canon iPF, and others. The majority of dirty lasers I've seen are Toshiba & HP, but only because they made up the largest proportion of the machines. It's more about the environment than about the make.

If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

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

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.
I have done it before, but you guys are talking like it is normal shit
