Hello,
I am having an issue with my PIXMA MG3620 printer in which it prints blank horizontal lines. I have cleaned the print head twice, deep cleaned once (the support page advises on only doing it once every 24 hours- https://support.usa.canon.com/kb/index?page=content&id=ART162783) and printed the test page multiple times to no avail. Each test page still shows a blank horizontal line for the blank ink. Can someone advise on whether manual cleaning is needed (along with what to do) or if I should just look into contacting support at this point?
