I've tried soaking in isopropyl alcohol and hot and cold ammonium hydroxide
(ammonia) as well as hot water, with no luck. Does someone know a better
way to unclog a Canon i550 print head?

YEAH, YOU CAN BUY AN IP4000 FOR $80 - $100 ON SALE WITH REBATE. YOU
ALSO GET A NEW SET OF CANON CARTS.

There are several tips in http://www.nifty-stuff.com/forum/ for clearing
Canon head clogs. Sign in, look for all the threads that have head cleaning
info, and post a question if you don't find what you need. In addition,
Arthur Entlich will send you his excellent Epson head cleaning manual if you
email him and request it. Although it is specifically for Epson printers
there is good info that can apply to Canons as well. Look at his cleaning
cartridge solution particularly. I have used cleaning carts filled with the
solution he described to clear an Epson print head clog. You don't have to
clean the print head the way he describes as the Canon print head is
removable and the Epson is not. Just look for his most recent post to get
his email address.

I have seen suggestions of dripping either distilled water, water/alcohol
combination, or windex (original) into the intake port of the blocked color,
reinstalling the cart, and running a purge print (purge files available from
MIS). Although it is a bit more involved, I would make cleaning carts and
run several purge pages. If you like the printer and don't want to spend
the money to buy a new one you have nothing to lose by trying these
techniques. Just don't soak the print head in deep enough fluid to get the
electrical contacts wet.

I have cleaned my i550 print head in hot water a couple of times with
success.

Recently, however, the failure mode is told by flashes of the LED on top of
the printer: 7 short orange flashes, then 1 long green flash.

I believe this means that the waste tank is full (perhaps measured by the
number of times I've used the maintenance menu to clean the print head.).

Apparently the only way to reset it is to return it to a service center,

I bought an ip4000.

I haven't decided whether to scrap the i550 (but my wife may decide for me).

Go back through the newsgroup with a google search or get on
www.nifty-stuff.com. There's been a lot of discussions on resetting the
warning and cleaning the waste ink pad. You'll really like the iP4000 but no
need to trash the i550. At least you can try the reset codes to see if they
work. It might come in handy late on.

Great Choice. Use OEM ink for best results.

Remove printhead and place on kitchen sink, fill an empty ink tank with hot
water, insert on printhead and hold tightly whilst injecting a syringe full
of hot water in inktank fill hole. Works a treat, 2 empty tanks, 3e & 6
required.

SIMPLE GREEN !

this stuff works great. I would soak the entire print head in SIMPLE GREEN then flush off with water and blow dry before reinstalling the print head. Make sure you dont blow out the little rubber gaskets where the cartridges rest.

Now I just remove the ink cartridge's and put a few drops of SIMPLE GREEN in each ink port where the little rubber gaskets are. Then reinstall the print head then the cartridges. Then just print anything a few times and the clogs will clear out. I have repeated this up to three times before it stops clogging but usually one time works. I do a lot of printing (2000 pages a month ) and my print heads clog every three or four months ?
