  If your Canon Fax Machine displays a BUSY/NO SIGNAL error (#018), it could be due to several reasons. The dialed number might be busy, in which case you should simply call again later. Alternatively, the receiving fax machine may not be responding within 55 seconds; ask the other party to verify their fax machine's condition and try transmitting manually. For international calls, try adding a pause in the programmed number. It's also possible their machine isn't a G3 fax, so ask them to send or receive using G3. Ensure that your machine’s tone/pulse dial settings are correctly programmed for your telephone line.

  The BUSY/NO SIGNAL error (#018) on your Canon Fax Machine can occur for several reasons. It might be due to the other fax machine not responding in time, meaning you should contact them to check their fax or try sending manually. If it's an international call, try inserting a pause in the phone number. The issue could also be that the other machine isn't a G3 fax, so ensure they send/receive in G3. Also, make sure your machine's tone/pulse dial settings are correct for your phone line. If the number you dialed is busy, simply try calling again later.
