Looks like the developer is spoiled or old. Try another know good developer unit. What happens when you force feed the K developer?

Or they are not using Genuine Ricoh toner.

Hmmmmm. No where in this post do they mention the toner supply. You may be on to something..

All toner in the machine is genuine Ricoh toner.

So I misread the previous comment regarding force feeding the developer and I executed a force feed of the black toner. However, I noticed that my black looks decent near the bottom of the test page but as you get towards the top, it gets worse.

The one on the right is near the top and left is near the bottom.

That is affecting all four colors, C M Y K. Something with either the ITB or the PTR. Start by cleaning the PTR. If it improves but doesn't eliminate then replace the PTR.

The ITB was replaced a few months ago and the PTR was cleaned as well. Since the issue still persists I guess that would leave the last option to replace the PTR?

Now that you say it, it does look like all colors are mottled or uneven.

That looks like it could be the PTR assembly itself that's broken or one of the large tension springs inside it is out of position.

Just curious, how and why would a faulty PTR result in mottling on solids?

The grounded paper transfer roller pulls the toner off the ITB onto the paper as it passes. On the '03 series a worn PTR can give all sorts of copy quality issues.

Not a Ricoh tech. Most of my experience is in large format offset presses.
