When the print head clogs on any of my Canon printers:
2 i960
1 i950
2 ip4000
I use the following technique.
Mix a solution of 20% household Ammonia (non detergent) and 80% distilled
water.
Fill an eye dropper with the solution.
Remove the cartridge or cartridges for the color that is clogged.
Drip a drop or two of the solution onto the intake for the printhead DO NOT
ALLOW THE DROPPER TO TOUCH THE INTAKE SCREEN!
Right away, replace the cartridges and run a deep cleaning cycle on the
printer.
Do it a second time if needed. In two years time I have only needed a second
application once.
