Black printhead needs clearning daily on 6960 Officejet Pro attached to Mac computers
Product: Example: PavilioOfficejet Pro 6960
Operating System: macOS 10.15 Catalina
The black ink is printing very streaky. Cleaning the printhead solves this but the head is needing cleaning on a daily basis. Not printing a huge volumn as on 300 page per month instant ink plan. Any ideas of how we can improve the situation.
