Product: MFP 377 dw
Operating System: Microsoft Windows 10 (64-bit)

My HP PageWide 377dw MFP is a couple of years old and has just recently starting printing vertical streaks in yellow, cyan and black about every 1 inch across the page.  

 

I've tried replacing the toner cartridges, cleaning level 1 and 2, and calibrating color density. I am unsure how to go about troubleshooting any further.

Please help.

Hello,

 

Hope you are well, based on the information provided, if you replace the toners with HP originals and issue remains even after the print head cleaning, at this point is better to reach an authorized service center for print bar repair.
