Thanks for that! There were so many replies, it was too tedious a task to find the key facts and follow the outcome of any action taken, if any. Good to hear there was follow through, though I will not reap any benefit.
MP530. Followed reset procedures many times. When it does work, printer prints a couple pages then locks up again with same error message. I do not see any recent solutions or actions posted. Are we contacting Canon individually?
