How can i fix printer roller marks on laser printer printouts?

HP Laserjet Professional CM1410 Series
I have replace the toner cartridges thinking maybe that was it and no luck.. I've blown out the printer with an air compressor (gently)
I cannot see an toner spilling out or anywhere in the printer.
The first page comes out clean but everything after progressively gets worse.
I've attached a blank page with the marks on itcheri-printer.pdf

It looks like a roller problem.

Toner is getting stuck on one and gradually building up during the printing process.  

The quickest way to identify the culprit is to take your print out sheet and measure the distance between the center of the print defects - that equates to the diameter of the roller with the problem.  

You can determine which roller it is with the value for the diameter and using the repetitive defect interval  measurement details in the service manual (p 103)

Clean or replace the roller involved.

Sounds more like an issue with the drum, possibly that if this system has a toner refuse collector ................

It sounds as though the toner adheres to the drum and is not cleared for the next page.  when the drum cools, the toner drops off creating the mess you mentioned.

Not sure whether your printer actually has one, was a thought.

if you print dual duplex (both sides of the pages) do both sides of the subsequent page have the same issue?

Presumably you no longer have HP warranty on this....
