My printer has been working fine up until now and the black ink cartridge is almost completely full. I have run several cleaning cycles, but the black ink comes out streaky or not at all. When I run a deep cleaning, it passes the nozzle check, but the actual printing still comes out streaky. Is there any way to inspect the cartridge when it doesn't need to be changed. The ink is actual Canon ink, not a knockoff, and it worked fine until yesterday,
