Canon S900-clogged printhead

While printing pictures today, there was a dark band running across the
bottom of the page. A nozzle check showed the bottom half the grid of
photo magenta doesn't print.

I did a several deep cleaning runs but there wasn't any change in the
nozzle check.

I have an S820 which is also a 6 ink printer head. Can I swap these?
Will there be any difference in photo quality if I do?

Is there anything else I can do to unplug the nozzle?

Thanks!

The two pinters use very different print heads although they do look remarkably
alike.
The s900 print head has about twice as many nozzles so even if the s820
printhead would fit it would not work.
There are techniques for recovering Canon print heads that have clogged, see
http://www.neilslade.com/papers/inkjetstuff.html for some info.
Also scan the messages at http://www.nifty-stuff.com/forum/index.php and if
there is nothing there ask a question in the forum.
I have had some success with Canon printheads using an ultrasonic cleaner but
nothing will work if the printhead has burned out.

Time to call it a day.

A few months ago when my s900 started to demonstrate symptoms of
aging, it really didn't make sense to blow $90 or so on a new head.
Notwithstanding that the expense of replacing Photo Cyan and Magenta
cartridges was starting to become somewhat annoying; when pics from
the latest generation of 4-colour printers displayed no obvious
deficit.

So . . . I bought an IP4200; and couldn't be more pleased! After
deducting the cost of the new ink cartridges included, it turned out
to be a mere $50 experiment. In printing out some of my old
"standardized" photos, and comparing them to the same photos printed
on the s900, I failed to observe the slightest deficit in the I4200,
compared to the s900 photos.
 
Thanks for the replies. Photos printed on my kids S820 look pretty good
to my untrained eye.

So, if a couple attempts at clearing the nozzle doesn't work, I'll take
theirs!

They don't show a perfect nozzle check either. Same color, they're only
missing the bottom row of the grid.
 
PROBABLY CAUSE BY AFTERMARKET INK

Not necessarily. Either the printhead inevitably reached its end of life,
or a dry cart was used too long, causing printhead burnout. It could also
be an electronic problem.

Gary we all understand that the fool meashershithead knows absolutely
nothing about ink, paper or printers.
He's mentally deranged. An idiot and a moron.
As you well know.
