Troubleshooting and routine maintenance
95
The machine does not answer
when called.
Make sure the machine is in the correct receiving mode for your setup. (See
Receiving a fax on page 39.) Check for a dial tone. If possible, call your machine
to hear it answer. If there is still no answer, check the telephone line cord
connection. If there is no ringing when you call your machine, ask your telephone
company to check the line.
Sending Faxes
Difficulties Suggestions
Poor sending quality. Try changing your resolution to Fine or S.Fine. Make a copy to check your
machine’s scanner operation. If the copy quality is not good, clean the scanner.
(See Cleaning the scanner glass on page 118.)
Transmission Verification Report
says ‘RESULT:ERROR’.
There is probably temporary noise or static on the line. Try sending the fax again.
If you send a PC FAX message and get ‘RESULT:NG’ on the Transmission
Verification Report, your machine may be out of memory. To free up extra
memory, you can turn off fax storage (see Turning off remote fax options on page
63), print fax messages in memory (see Printing a fax from the memory on page
45) or cancel a delayed fax or polling job (see Checking and cancelling waiting
jobs on page 38). If the problem continues, ask the telephone company to check
your phone line.
If you often get transmission errors due to possible interference on the phone line,
try changing the Compatibility setting to Basic. (See Compatibility on page 105.)
Vertical black lines when sending. If the copy you made shows the same problem, clean the scanner. (See Cleaning
the scanner glass on page 118.)
Handling Incoming Calls
Difficulties Suggestions
The machine ‘Hears’ a voice as a
CNG Tone.
If Fax Detect is set to on, your machine is more sensitive to sounds. It may
mistakenly interpret certain voices or music on the line as a fax machine calling
and respond with fax receiving tones. Deactivate the machine by pressing
Stop/Exit. Try avoiding this problem by turning Fax Detect to off. (See Fax Detect
on page 42.)
Sending a Fax Call to the machine. If you answered on an external or extension phone, press your Fax Receive Code
(default setting is (l 51)). When your machine answers, hang up.
Custom features on a single line. If you have Call Waiting, Call Waiting/Caller ID, Voice Mail, an answering
machine, an alarm system or other custom feature on a single phone line with your
machine, it may create a problem sending or receiving faxes.
For Example: If you subscribe to Call Waiting or some other custom service and
its signal comes through the line while your machine is sending or receiving a fax,
the signal can temporarily interrupt or disrupt the faxes. Brother’s ECM feature
should help overcome this problem. This condition is related to the telephone
system industry and is common to all devices that send and receive information
on a single, shared line with custom features. If avoiding a slight interruption is
crucial to your business, a separate line with no custom features is recommended.
