Checking the Dial Tone before Sending
Checking the Dial Tone before Sending
The following redirection problem may happen with certain kinds of fax machines on the
market made by companies other than Canon. The Check Tone Before Sending mode
prevents this rare occurrence from happening.
If you are sending a fax document from your machine at the same time another fax machine
(made by a company other than Canon) is trying to send you a fax, your fax document may
end up being redirected to that fax machine, instead of the original destination you had
intended.
Setting <Check Tone Before Sending> to <On> enables you to avoid such sending problems.
The default setting is <On>.
