I don't see how this could have anything to do with refilling the
cartridge.  I mean, the whole print head IS the cartridge.  If you
replace the cartridge, you'd have to invoke homeopathic magic to
blame it on the previous cartridge!

To the guy that claimed that your HP repair guy would be able to tell
the difference between HP clogged ink and so-called "bogus" clogged 
ink -- NONSENSE!  Do your really believe that the HP repair guy is
going to send out samples of your clogged ink to a chemical analysis
to determine if he should void the waranty or not?  Nobody has that
amount of luxury time available.

When I had my HP DeskJet Plus taken apart to pieces (a very easy
task, by the way) I saw the little plastic tube that runs the primed
ink down to a blotter pad in the base of the unit.  It certainly
wouldn't take a rocket scientist to figure out how to clean the
tube out if it did become clogged!  (The fact that HP ink is 
air drying and so is "bogus" ink, leads me to seriously doubt that
one is more likely to clog than the other.)

The type of person who refills ink cartridges is almost suredly the
same type of person who will take the skins off the DJ+ to clean
his own plastic tube.  Let HP make is ripoff money off the types
who don't know which end of a soldering iron to hold.  I'll gladly
continue to (start to) refill my cartridge without fear of HP
detection or loss of waranty.
