Using Officejet Pro L7680 All-in-One printer with Macintosh v10.9 upgrade to 10.9 recently added. Printer purchased for home use, 2008
When I print a page containing a color photo, the result includes thin white horizontal lines across the photos.
Some black & white photos show lines. Some color do not have lines
I have tried, align printer, clean printhead, calibrate linefeed, changed magenta ink with no change,
did self test diagnostic page and printheads rated, Black Yellow good, Magenta/Cyan fair.
Should I consider replacing Magenta,Cyan print head?
