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 gain extra memory,
you can turn off Advanced Fax Operation (see Turning off Advanced Fax
Operation on page 59), print fax messages in memory (see Printing a fax from the
memory on page 37) or cancel a Delayed Fax or Polling Job (see Canceling a fax
in progress on page 27). 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 menu setting of Compatibility to Basic. (See Phone line
interference on page 111.)
