I had a similar problem with my IP4000. I tried all the solutions suggested but to no avail. I also used Markett to buy a new printhead. It was the best price by far and solved the problem immediately. I suggest you try the cleaning suggestions first though - a new printhead was not cheap!

am unfamiliar with the Canon set up except those with Thermal Jet cartridges.
I gather this model has built in heads like Epson.
When my Epson head clog- or a get one to unclog from one of my flock, this homemade gadget does the trick.

Put head in saucer of hot distilled water (1/4 inch), gently shack till water comes clear. Repeat with hot water. Leave in saucer over night. Repeat hot water in saucer for second night.
Dry carefully with paper towel. If this does not work,a new head is required. I have used this twice and got a 100% matrix printout following missing print lines because the head was partially blocked - it DOES work. David

Further to the above post -
Also pour small amounts of hot water onto each of the spigots on the inside of the head, so hot water will flow into the saucer.
"Shack" should read "shake". David

I usually save a set of empty carts. I can flush them clean and fill them with distilled water to which has been added ONE DROP of mild detergent or contact lens cleaner, to 250ml of liquid. After the overnight soak, as per David4637, replace the head and perform several head clean cycles. This usually has the desired effect.
I lost a printer to a blocked head, some years ago, and I now do a test strip print of my inkjet printers every week as part of my routine backup do backup, don't you???
All the best

Try to build into you routine a full colour print at least once a week- more often in summer heat or Winter central fug.
