Cleaning Clogged Print Heads

I have had very good luck cleaning dried or clogged printheads by using a waterpick. The litle pressure washer for your teeth. Just wash the nozzles with the waterpick. Sort of a miniture pressure washer. It can get you wet so its best to hold the cartrige in some sort of container to prevent getting to wet. Wash long enough to dislodge the dried ink, or soak the cartrige for a while befor cleaning.

SX200 Not Printing

Not sure how you will have removed the dry ink but there will undoubtedly be more clogged ink in the printheads and nozzles themselves.
There's two approaches to resolve the issue...
1. Active
Through the use of a cleaning solution that you effectively force into the appropriate ink receiver on the printhead.
This can delaminate (technical term: knacker/mess-up) the printhead so avoid the use of anything other than the gentlest of pressure.
2. Passive
Get the printhead off the cleaning station (where it normally rests when not in use) and then soak the cleaning station pad with cleaning solution (so you have a puddle)... Return the printhead to it's normal resting position and leave the printer disconnected from power for a few hours. You then plugin and switch printer back on and it will purge the solution out of the cleaning station. Print one nozzle check then repeat as required. Be prepared to leave overnight to allow the cleaning solution to wick into the nozzles and break the clog does like soaking dishes in a sink.
You could use both methods in tandem to tackle the clog from both sides but patience and time are both critical ingredients. Expect it to take up to a couple of days.
Best of luck.

HP print heads that work with water-based inks can be fixed using a lint-free cloth wetted with luke-warm water. First wipe off all the gunk outside the bottom chip, taking care to NOT touching the chip itself - avoiding to be careful can clog the printhead even more! Then gently dab the printhead on the wet cloth, letting the water sorta slosh around the chip, cleaning the nozzles. You could also let the printhead sit on the cloth for five minutes or so. This will both draw out new ink from the nozzles and dissolve any dried ink that are clogging them. Be careful NOT TO WIPE OVER THE BOTTOM CHIP, since this most probably will wipe dried ink into the nozzles! With newer, solvent-based inks, you could use either pure alcohol (NOT ACETONE, THINNER OR ANY PETROLEUM-BASED SOLVENTS!) or isopropanol to do the same thing, and doing an ink cleaning in the driver immediately after this procedure. However, the best way to avoid the printheads clogging up, is to use the printer regularly and leave it powered on so it can do its own cleaning. Shutting it off after use will speed up the clogging process no matter how you look at it. Also, using HP's own ink systems instead of aftermarket stuff, will give you "peace of mind" since things are always new, HP doesn't refill/reuse their cartridges and printheads. "Always clear, always sharp!" :) Also, cleaning the contact matrix in the printer's carriage and the carriage itself is a good way to avoid dust and other kinds of debris to enter the printhead nozzles. Do this at least twice a year and you should experience no probs with your printheads. Hope this helps. This method ought to be appliccable to other brands as well, but I've never tried since I work exclusively with HP printers. //Al

My 6M ink will not print. I have tried cleaning and deep cleaning but nothing. I am concerned the ink may have dried in the head as I was out for a while and did not get it replaced.

I do not recommend deep cleaning, it wastes a lot of ink. If you don't see improvement after each cleaning, the printhead is most likely clogged. You can attempt to wash it out, running the nozzles under warm water, and allowing it to dry for a day. Don't use air or any chemicals, and don't touch the contacts or nozzles.
Sometimes it will recover, it is more likely it won't. A new printhead might be in order.

Printer will not print anything, has been working very good up to this point.

Most likely your print head is clogged, there are 2,000 some nozzle's in it. If the printer is not used for a moderate amount of time the ink can dry up and cause a clog in those nozzle's. You can try reseating the ink cartridges(take them out turn off power, unplug printer, power back on & wait for it to get done making noise) then proceed doing a printhead clean from the main menu, or homecenter->?->maintenance. Then after that do a calibration, print a demo sheet to see if there is any improvment. The printhead clean pushes ink through the nozzles to try to clear clogs. The calibration scans those nozzles to see which are avalible to use, and makes sure that all the avalible nozzles are being used. If this does not fix the problem you most likely need a printhead but you will have to call kodak; as they are not avalible in stores. Also you can try updating your firmware from kodak home center, or www.kodak.com/go/downloads
