The good news is that you MAY be able to solve the problem using some basic household products. In fact, Windex glass cleaner can actually work well for dissolving dried ink. What’s the secret ingredient?

Ammonia.

Tough printhead clogs can usually be brought into submission by soaking the printhead in a solution of 50/50% ammonia and distilled water.

A important word of warning… ammonia is potent and powerful stuff. When working with ammonia, always make sure you’ve got adequate ventilation, and avoid mixing it with other chemicals. Very important.

So, if your printhead is located on the inkjet cartridge itself, you’ll want to soak the printhead in the 50/50 solution for an hour or two.

If the printhead unit is located inside your inkjet printer itself, then you’ll first need to remove the inkjet cartridges. After those are removed, put some of the solution into the top of the printhead (directly into the nozzle holes) and let it sit a few hours. Go ahead and put a little more into the printhead resting seat. (This is the rubber rectangle part that seals off the printhead unit while the carriage is in its resting position.)

If this initial soaking doesn’t work, then repeat another time using 100% ammonia for up to one hour. Afterward, make sure to rinse completely with distilled water.

If the clog doesn’t immediately clear, go ahead and let the printer sit overnight and try it again the next day. Sometimes the clog will breakdown slowly and release later as the ammonia takes its toll.

Finally, for those of you wondering about the effectiveness of using alcohol to unclog cartridges and printhead - here’s a quick note…

Alcohol won’t work as well as ammonia, but may work better than a few cleaning cycles. The downside is that alcohol may actually dry out the plastics and metals in the printhead. This could actually increase the chances of clogging later on down the road. So try to avoid alcohol if possible.

91% isopropyl alcohol could be too strong and damage some plastic parts. Alcohol makes ink dry and some pigment ink can turn into jell and clog the head so it is not recommended to clean print heads.

You can use ammonia + distilled water solution, put only a few drops of ammonia into water solution. The cotton swabs and paper towels are also not recommended also because micro fibers can clog or scrape the print head nozzles.

You should always use coffee filters they are safe to use, no rubbing the nozzles should be always avoided if possible.

My recipe for print head cleaning:

1. Soak the print head in distilled water until it is very clear. Use a small plastic container that did not contain any chemicals in it before procedure. Single use containers should be used.
2. Leave the head in distilled water solution for 24hrs. Make sure water level covers ink inlet ports too.
3. Change distilled water in the container and heat it to degrees 40-50C. Too hot can damage the dead so make sure to not overheat the water. When the water is ready submerge the head into the container for 15mins or so. Make at least 4 cleaning cycles this way.
4. Put a coffee filter on the table, underneath the coffee filter put 3 - 4 sheets of paper towel to absorb the cleaning solution.
5. Put the print head on the coffee filter and get some soda straws (they are ideal for ink ports on pixma printers) remove rubber padding around ink ports on the print head by using some instrument as tweezers. Recommended way is to submerge the head into distilled water because rubber padding can be removed easily without friction in water. Now when you are ready connect each soda straw to every ink port.
6. Make a cleaning solution by using few drops of ammonia solution and distilled water. For example 2ml of ammonia and 19ml of water in a 20ml syringe. Mix the solution by shaking the syringe.
7. Fill the soda straws with cleaning solution. If you get air pockets in the straws use another 20ml syringe to connect and force air trough the straws until there are no more air pockets and solution level is decreasing in the straws. Take some patience the method is slow but well worth it. The solution should decrease faster as more nozzles are cleared. Don’t hesitate to use the empty syringe to force some air trough the nozzles if you get air stuck when filling the straws.
8. Finish the cleaning by injecting pure distilled water and by submerging the print head into distilled water for 15mins. Then blow the ports with air using a syringe with a soda straw.
9. Clean the gold contacts on the head with some isopropyl alcohol and then immediately install into printer and perform 2 to 5 cleaning cycles or some deep cleaning to prime the head, and then print some purge pages. Now you can print nozzle check to see how well the cleaning unclogged the nozzles.

Ink refill instructions for
Canon
CL 41
( #41 )
ink cartridges

Instructions 1.     The filler pads of the cartridge are located under the top.  Remove the top before refilling by carefully prying it off with pocket knife. 2.    Insert the filling needle into the filler pad of the color to be refilled. 4.    Slowly inject up to 5ml. of ink until the sponge is saturated. Important:  When you take off the color cartridge cap will notice that the sponge is white.  Do not change the sponge color.  Fill the individual colors until the color just begins to show in the white sponge. 5. After refilling the top can be put back on with scotch tape. 6. Replace the cartridge and run 1 - 3 cleaning cycles as per printer instructions. If necessary leave cartridge in printer for up to 24 hours. (Allows ink to flow to the print head).

Note: Each time the cartridge is removed from the printer an "empty cartridge" message appears and a blinking amber light will come on, on the printer. Holding the paper feed button down for 3-5 sec. will allow you to override the counter.
