Pixma 5320 won't print black

[PMHilton]

Pixma 5320 some time ago stopped printing black. I placed the print head in a shallow dish of Windex for 2-3 hours and all was fine for several months. Today it stopped printing black, but soaking print head did not help. Installed brand new OEM printhead and Canon 225 cartridge. Still no black. Colors on nozzle check are fine but no black. What to do?
