Product: HP Officejet Pro 8630
Operating System: macOS 10.14 Mojave
Hi there - my officejet pro recently started printing thin horizontal lines spaced approx 1" apart (it looks like a darker version of whatever color it runs over - maybe an overlap?) when I print on any type of media. For years prior it had not done this, this is a new problem.
I ran the print quality diagnostic page, and then based on the results, I ran the "calibrate linefeed" function. This did not do anything to help with the problem.
Has anyone had a similar experience and can you offer any suggestions?
Thank you!
