Troubleshooting and routine maintenance

C
The machine does not answer
when called. Make sure the machine is in the correct receive mode for your setup. (See
Receiving a fax on page 41.) 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 you do not hear 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 on page 138.)
Transmission Verification Report
says ‘RESULT:ERROR’. There is probably temporary noise or static on the line. Try sending the fax again.
If you are sending a PC Fax message and get ‘RESULT:ERROR’ 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 46) or cancel a delayed fax or polling job (See Checking and
cancelling waiting jobs on page 39). If the problem continues, ask the telephone
company to check your telephone line.
If you often get transmission errors due to possible interference on the telephone
line, try changing the Compatibility setting to Basic(for VoIP). (See
Telephone line interference on page 124.)
Vertical black lines when sending. Black vertical lines on faxes you send are typically caused by dirt or correction
fluid on the glass strip. (See Cleaning the scanner on page 138.)
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 44.)
Sending a Fax Call to the machine. If you answered on an external or extension telephone, press your Remote
Activation Code (default setting is l51). When your machine answers, hang up.
Custom features on a single line. If you have Call Waiting, Call Waiting/Caller ID, Caller ID, Voice Mail, an
answering machine, an alarm system or other custom feature on a single
telephone 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. KONICA MINOLTA 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.
