My printer Canon MP760 does not print bla...

Dear Sir,

Change the Black catrdge first. if the same things happen u have to clean the head once. Go to Printer Settings and preference there clean the head.

Cheers

Your black ink must be empty replace with a new one and print.

The black printhead/nozzle is clogged. Try performing the head cleaning procedure using Canon software, do it several times.

If that does not work, the printhead must be replaced.

Before replacing you can try removing the ink carriage with printheads/nozzles, and soak it in isopropyl alcohol for a couple of days.Another good way to fix clogged printheads that sometimes work is using a Cleaning Cartridge Canon I950 I960 Mp760
