Canon MX922 can't fax always get "Line Busy" #018



Hi, I have a Canon MX922 printer, and I cannot send a fax.  I can hear it dial the number, the other fax answers (I sent it to a friend) but the MX922 continues to say calling on the LED and eventually hangs up with a "line busy" report #018.  I have tried reducing the sending speed and disabling the ECM TX, still the same.  Have tried faxing multiple numbers with the same result. So it would seem to not be a problem with the destination fax machines.  Also checked the phone line - fine.

It could be also a telephone network problem or the fax line. To verify this, try to use a different fax machine connected to your fax line. If it also fails, therefore the fax line is faulty.
