Troubleshooting and routine maintenance
103
Phone Line or Connections
Difficulties Suggestions
Dialing does not work. Check for a dial tone.
Change Tone/Pulse setting. (See the Quick Setup Guide.)
Check all line cord connections.
Check that the machine is plugged in and switched on.
Send a manual fax by pressing Hook or by lifting the handset of the external
phone and dialing the number. Wait to hear fax receiving tones before pressing
Start.
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 40.) 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 128.)
Transmission Verification Report
says ‘RESULT:NG’. 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 66), 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 canceling
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 Phone line interference on
page 115.)
Vertical black lines when sending. If the copy you made shows the same problem, clean the scanner. (See Cleaning
the scanner glass on page 128.)
Handling Incoming Calls
Difficulties Suggestions
The machine ‘Hears’ a voice as a
CNG Tone. If Easy Receive 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 Easy Receive to off. (See Easy
Receive 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.
