blue ink appearing on page

laserjet pro 400 color M451dw
Microsoft Windows 10 (64-bit)

Pinter is intermittently printing/spraying blue ink in an area 2" to 3" from the top of page in the center.

The pattern of spray may change but not the location.

I have replaced the blue cartridge (HP brand 305a)

Out of a ten page document, it might happen on first page only, all ten pages, or zero pages.

I have switch from color to black and white mode (and back) with no effect.   

Any possible solutions?

I have seen non-HP toner cartridges cause a spattering/spraying of toner due to bad cartridges, but rarely an HP branded cartridge, but it can happen, and usually not two cartridges in a row. Is the printer on a solid flat surface large enough to support it properly and not on a slope of any kind? Is the toner pull-out tray straight and moving freely?
