Thanks in advance for any help offered.
We have a Customer whose aging ImageRunner 5000 recently started making a horrendous racket while printing, and the pages that come out are very very faint.
Through the front I removed everything necessary to take out the Drum (I have the Service Manual), but after reading this forum I decided not to. From what I saw from both the front and the right side, the drum moves properly, and the surface is free from defects.
I opened a portion of the right back corner (near the power switch), and can see a tensioner start jumping all over seemingly coinciding with the noise.
Shortly before/while printing the last page or two the noise stops.
I'll be attaching 2 brief videos, one of which i recorded from this "inside" vantage point.
I'm pretty sure the problem is something the developer unit is geared with.
I removed the Developer unit and the gears turn fine, and the toner seems distributed evenly, so I don't believe it is the unit itself.
I even marked the gears, and test printed to confirm the gears (on the Developer) are in fact moving when it is printing.
It is my belief they are not turning enough, and it is related to the clicking.
Every gear I was able to see looks to be in good shape, and is able to turn.
Here is an example of the Printout:

Here's a video from the front of the copier:

Here's the "internal" video I referenced (NOTE: the middle portion of this video is slo-mo):

If somebody could give me some feedback, or suggestions I'd appreciate it a whole lot.
