I see it's a repetitive pattern of spots.
Can be a noise from PC network but if this pattern exist already, when you print using machine usb port, then is something with internal electronic boards or internal hdd. Try to reseat the memories dimm and all connectors inside machine. Never seen this pattern before.

This might be stupid, but could someone have set up a "default watermark" on that machine?
On the pictures it looks a little like the repeating pattern has somewhat of an alphanumeric pattern. As such, that's something I'd check anyway.
Sorry if that was a waste of time.

Are you printing from a PDF file or maybe off the web HTML?Is it the same for other PC's connected to the printer?Looks like an image or author copyright encoding. You might not see it until the screen colours are converted to nearest PCL colour.

Is the developer yellow clear?
Or there is black contamination in the yellow developer housing?
