Printing Black & Pink Streaks

[lagb]

I had to recently replace the laser scanner assembly. I did transport the printer to have it replaced. Now that it's back home, it prints with black and pink (or red) streaks. I've updated the software, I've run the supplies status report (I have plenty of ink), I've run the diagnostics page, and the print quality page. I've done a color calibration. I've checked the print drums (without touching them) and they all look spotless. I checked the chips on each ink cartridge to make sure they are in good shape.  I've tried looking this up online on various websites, include HP and haven't found anything regarding my specific issue.  The attached print quality page shows white streaks and even check marks on the gray section. Those don't show when I copy or print.

Bad cartridges would be my first guess. Did you recently change them? Are these OEM or 3rd party? The white streak on the right side of the page looks more like a transfer belt or fuser issue. Measure the spacing on the defects and refer to the repetitive defect chart for your printer and it will tell you. Could be an issue with the HVPS but then I would expect to see the issue on all colors.

Thank you for your suggestions. The cartridges are the original ones that came with the printer. I will look into your other suggestions and report back.
