New transfer and charge rollers, new fuser, different toners tried; still getting a noticeable light print down the complete left side of page. HVPS? Electrical bearing? Had to get back in the field for other work and have not finished the machine. I got everything back to operation except this print quality issue. Any thoughts appreciated.
TIA
Have you cleaned the lase slit glass yet? It sounds like you've covered all the other logical choices. =^..^=
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.

Ah, something I did overlook. I will check into it when I get back to the workbench. I'll let you know if it improves.

I've seen light print over an entire page, but not where it's just on the left margin, however....
transfer roller springs out of position on one side? if it is, it may account for light print. same with the charge roller arms (make sure springs are attached and in position correctly. Have to take front and top cover off to check that.
OK, thanks, I will look at those when I am back at the bench. I've taken these units apart pretty far, so getting the covers off is no problem....
more common problem is toner or dust on laser scanner mirrors/lenses. I would try that first as blackcat recommended. Either way you're going to have the top cover off. I take the scanner completely out, open it and blow out any dust or other obstruction. (swabbing only if blowing out doesnt work).
Oh and by the way, pay attention to the registration, unlike HP scanners, lexmarks can be adjusted by moving position of the screws. You should be able to print with the top cover off, but you'll need the front door on. In service mode you can adjust registration too. I know this is a side point but its something I ran into before.
(Some idiot tech friend put a piece of black tape over one side of the scanner one time a joke. After 1.5 hours of troubleshooting, I figured it out. I did NOT think it was as funny as he did!)

Printer looks OK now as far as printing. A "new" bad charge roller looks to be the suspect. Installing yet another new charge roller gave much more acceptable results.
Now the door close micro switch is also acting up, need to replace that....always something.
Look at transfer & laser process. Ensure first that machine is leveled evenly. Leveling deffect are like u have said
You can get faint print on one side by reversing the transfer roller too.
