Users while working on Canon printers can sometimes come across an error message
which will appear as “U075” by clearly defining that the device is well capable
of reading the cartridge but it is detected in the wrong side. Though it is
known that the colored one and black cartridges look quite similar to each other
and the other two cartridge positions within the printer are identical, it is
suggested that both the cartridges should be installed in an appropriate
position for the printer to recognize them accurately.
