Do I have to purge the system of all traces of the previous ink ( don't even know what that would entail )or just do one or more "deep cleanings" or what? For instance, changing from one brand of 3rd party ink &amp; their cartridges to another 3rd party ink with their refillable cartidges.</P> Wed, 29 Mar 2017 15:35:02 GMT brassman 2017-03-29T15:35:02Z https://community.usa.canon.com/t5/General-Discussion/Changing-ink-brand-procedure/m-p/204855#M22903 <P>What is required when changing from one ink brand to another on the same printer?
