Solution 4d:

My Canon MX860 locked up with the B200 error when I continued printing without black ink. I removed printhead as described elsewhere and carefully flushed with hot tap water until no further ink waste was present. Reinstalled, but this did not resolve the B200 message and lockout.

Removed printhead again and this time removed 2 small screws (with jeweler's scredriver) on printhead to dimantle it. Use care to protect the ribbon cable. Do not try to remove this cable. You will see a complex rubber gasket. Remove this and clean with hot water. Set aside.

With screws removed, this will give access for more cleaning of the ink passages. Used hot water, then isopropal alcohol to wash, and finally a small (1/4") soft rubber tube to gently blow out water/alcohol from the printhead body. Be careful to not touch or push on the ink jets (little metal strips - large set for color; second set for black printing). Dried parts and reassembled. Carefully replace the gasket so that it fits over the plastic tips of the several ink ports.

Error B200 has disappeared

Ran printer maintenance from the PC: head deep cleaning, regular cleaning 3 times and head alignment check. Gradually print quality has been restored as ink has flowed into the printhead cavity and to the ink jets.

Solution 5:

Clean the printhead

Solution 5a:

Replace the Printhead

Solution 6:

Replace the power supply unit.

Solution 7:

Replace the logic board.
