I replaced a black ink cartridge (genuine, canon 251) this morning and suddenly my printer isn't printing jobs. Printer status shows ink as correctly installed and ink level full.
Using Film maker v 10 to print transparencies for silk screening. Printer connected to desktop via USB cable.
Test page prints fine.
Nozzle check prints fine. No clog.
However, when I try to print a film, the printer just passes the film right through and doesn't print.
What do I do?
