Blue dots on all pages

I have Color LaserJet Pro MFP M277dw and I'm getting blue dots printing on every page - spaced 1 inch or so apart down center of page.  Any help or guidance on this?

 

I have tried cleaning the machine.

The cyan cartridge is at 70%

If you get cyan dots on all pages then you likely have either a defective cartridge or there is something stuck on the drum of the cyan cartridge. Remove the cyan cartridge and check the bottom of the cartridge and look at the blue/green cylinder. It should be smooth with nothing sticking to it.
