Memo: If a trouble occurs in communication with a non-Canon machine, and if a Canon machine operates properly without
any problems, it is recommended to let the user understand that the non-Canon machine needs to be examined
accordingly. Since the cause of the trouble may exists in communication ability of the machine, contact a relevant
