How does the B200 error differ from other common Canon Pixma errors like 5B00 or 1403?

The B200 error specifically points to a printhead malfunction or a main logic board issue affecting the printhead, often indicating a hardware failure. In contrast, error 5B00 (or 5B0x) typically indicates a full waste ink absorber, which requires resetting the waste ink counter and potentially replacing the absorber pads. Error 1403 (or similar 14xx codes) often suggests an issue with the printhead not being installed correctly or being incompatible, which can sometimes be resolved by re-seating or replacing the printhead, but usually without the deeper electrical fault implication of a B200. The B200 is generally considered a more critical and harder-to-resolve hardware failure than most other common Canon errors.
