Hi Joe,
You covered all the options. I can add a picture of an issue of 2ND BTR wich is part of Maintenance Kit and hwo may cause Light print. It will be better if we can see an image proof with issue.

Troubleshoot to find where the problem is.
1. Print with no PC or driver, does it still occur? (You can submit a print job via EWS > Home > Submit File
It works with .pdf, .ps, .pcl, .prn, .xps, .jpg, .tif, or .txt. files
That will tell you if you are troubleshooting hardware or software.
2. If it is still bad, a simple thing is to just update the firmware, it probably won't work (there is no "all the sudden prints are garbage for no reason bugs that I know of), but it can't hurt and doesn't cost money either.
3. If it still fails to get good results, check that the paper isn't humid, and that it isn't loaded as plain when it is really cardstock or some other setup.
4. If it worked via EWS, the issue is the PC/Software/Driver. So does it happen with a particular Application? Indesign has some things that cause this issue (can be resolved), Acrobat/Reader has also had some similar bugs that could be worked around/fixed.
5. If it happens from all applications, look to the driver, and here there are many options, don't just reinstall the same driver, change them up completely, you Have the native driver in both PS and PCL, then there is the Global Print driver, which has PS, PCL5 and PCL6. They are made by different people in different teams in different locations, they won't all behave the same, and if they do, the driver has been eliminated from the equation as well.
6. Hardware (Now we are looking into the money things) It is possible the print engine is toast, though I have never heard of it actually happening without a plethora of faults, usually unable to boot up. The Fuser could be bad (Mottling due to overheating) A drum, Maintenance kit needed. I don't think it is any of these, especially since they are such long life items. So wait and see if Gabiene sees this and has anything to add
