How to unplug Canon print heads.
Remove the print head from the printer. Pour enough Print Head Clog Buster into a glass cereal bowl (about ) so that the you can immerse the nozzles into the Print Head Clog Buster. Allow the print head to sit in the Clog Buster for at least 24 hours. You can take the syringe and drop some Print Head Clog Buster into the screened inlets in the top of the print head. Remove and use a can of compressed air to blow through the screened inlets out the bottom of the nozzles. Use a pair of safety glasses to prevent any ink and compressed air from coming back into your face to protect your eyes. Do not get any liquids including Print Head Clog Buster on the gold contacts of the print head. If you inadvertently touch the gold contacts, wipe them down with some Isopropyl Alcohol.
Reinstall the print head into the printer.
On a scale of 1 to 10, 10 being the most difficult the Canon print head is one of the easiest to service. The Canon print head is very durable and reliable. In my estimation the Canon printer is one of the best on the market today. The Canon printer is also about the least expensive printer to run. Unlike most of the printers on the market the Canon ink cartridges are very easy to refill.
