posted earlier to two other newsgroups...

So, I have this printer the Canon MX700 all-in-one.

Which, I would recommend, only as the inks are affordable if you use
refurbs and such. Basically $2 an ink cart.

But, buyer beware, what will $2 get you? Pretty sure you can omit "quality".

I have two questions:

1) How do you know when your print-head has gone bad? I took it off,
soaked it in alcohol, put it back and it was a little better, but not
completely. Seriously, is there any difference between a new print head
and mine other than the new one isn't clogged?

and

2) Actually, I only have that one question.

Thanks in advance

Mr. Curious

From my experience and reading, the ink nozzles eventually burn out.
That, and some inks (black, for instance) can take days of soaking, and
pressure, to get it all out (took 9 days before a massive amount of ink
came out of an old Epson PM-670C head last year). If you're sure you
have gotten all the ink out, and some color still does not work, it may
be that the nozzles are simply burnt out. A way to check that is to see
if on cleaning the inks does come out, but it does not print.

I am not sure how air bubbles affect the above phenomenon---maybe you
can have a stray air bubble still interfering.

Soaking the head overnight in rubbing alcohol didn't do the trick.
Swapping out a cheap Cyan cart for a different, but sealed, Cyan cart
--- did.

The Black (the printer uses 4 different inks) still is not *perfect*,
and but at least now I feel as though I am back to "average".

Glad to hear that worked in your case.

Yes, some you lose, some you win, and some you draw :-)
