I have similar problem. I found this solution that may help you. My problem insists tho.

>>> 5 flashes indicates a faulty printhead or possibly a problem with the p/head contacts. Try removing the head which is easier if you take the cartridges out first(no tools required) and re-seat it having checked the contacts for dirt.

If that doesn't work it may be that the waste ink tank is full. Try this ...
Canon S9000, S300, S400, i550, i560, i850, i860, i865, i9100, i9950, PIXMA iP3000 above,
1. Turn off printer
2. Hold down Resume button and press Power button.
3. Keep holding down Power button and let Resume button go.
4. Press Resume button 2 times then let BOTH buttons go.
5. Green lights will flash and then stop blinking.
6. When green lights are solid, press the Resume button 4 times.
7. Press the Power button and the printer should turn off, if not, press the Power button once more.
8. Your printer should respond as normal.

The cartridges have small chips on the lower face Once it registers empty that casette will not woek again. Many of the replacement cartridges that are not genuine have this chip missing. You can transfer the old chip to the new vcartroidge ( if its not a genuine with a replacement reset chip. I think you can by a chip resetter for this model. do a web search fot your model they are por etty cheap to buy
