SUGGESTIONS
Try changing your resolution to Fine or S.Fine. Make a copy to check
your MFC's scanner operation. If copy quality is not good, clean the
scanner. (See Cleaning the scanner on page 22-24.)
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' or, on
the Transmission Verification Report, your MFC may be out of memory.
To gain extra memory, you can turn off Fax Storage (see Setting Fax
Storage on page 8-2), print fax messages in memory (see Polling on
page 5-10) or cancel a Delayed Fax or Polling Job (see Cancelling a job
while scanning the document on page 6-12). If the problem continues,
ask the telephone company to check your phone line.
If the copy you made shows the same problem, your scanner is dirty.
(See Cleaning the scanner on page 22-24.)
If your MFC is set to Fax Detect ON, it is more sensitive to sounds. Your
MFC may mistakenly interpret certain voices or music on the line as a
calling fax machine and respond with fax receiving tones. Deactivate the
fax by pressing Stop/Exit. Try avoiding this problem by turning Fax
Detect to OFF. (See Fax Detect on page 5-4.)
If you answered at the MFC, press Start and hang up immediately. If
you answered on an external or extension phone, enter your Remote
Activation Code (default setting is (
hang up.
If you have Call Waiting, Call Waiting/Caller ID, RingMaster, Voice Mail,
an answering machine, an alarm system or other custom feature on a
single phone line with your MFC, it may create a problem sending or
receiving fax data.
Make sure that MFC is in Fax mode. If the Fax
illuminated, press it to turn on Fax mode. Setup Receive Setting (Menu,
2, 1) and Setup Send Setting (Menu, 2, 2) are available only when the
MFC is in Fax mode.
Sometimes you may see vertical streaks on your copies. Either the
scanner or the primary corona wire for printing is dirty. Clean them both.
(See Cleaning the scanner on page 22-24 and Cleaning the drum unit
on page 22-26.)
