If you are not sure about what type of line you have, contact your local
telephone company. See p. 14.
•Has the document been fed correctly into the FAXPHONE?
Remove the document, stack it and feed it into the FAXPHONE

oAre the images you send or copy spotted or dirty?
•Is the document scanning glass clean?
If the scanning glass is dirty, clean it. See p. 88.
•Is the other party’s fax working properly?
To confirm correct operation of your own FAXPHONE, make a copy. If

release it.
Make sure a document is set in the Automatic Document Feeder (ADF)
and the LCD displays DOCUMENT READY.

oMultiple sheets feed into the FAXPHONE.
•Make sure the paper is not sticking together. Fan the paper before load-
ing it into the paper tray. Always fan a stack of paper along the edge that
will feed into the FAXPHONE first.
•Make sure the paper tray does not contain too much paper. Remove a few
sheets of paper from the paper tray.
•If different paper types are loaded in the paper tray, load just one paper
type. See Loading the paper, p. 6.
oPaper is loaded skewed (Printing is skewed).
•Make sure the paper is loaded properly in the paper tray: the right side of
the paper is aligned against the right side of the paper tray and the paper
guide rests against the left side of the paper stack, see Loading the paper,
p. 6.GENERAL
oSending and receiving documents too slow?
• When sending, is the document mode set to FINE or PHOTO?
Before sending documents, press [RESOLUTION MODE] until
STANDARD appears on the display. Sending will be faster, but the
image will not be as clear, and photos will be reproduced in black and
white only.
• Is your FAXPHONE set for ECM sending or receiving?
Because the fax is constantly checking for errors during transmission,
ECM sending and receiving require more time. If the transmission speed
appears to be extremely slow, you may be able to speed it up by turning
ECM off. See pp. 76 and 77. 
						

							96oCannot get faxes from information services?
•Is your FAXPHONE connected to a rotary dial telephone line?
Press [TONE] to receive faxes from information services that require
touch-tone telephone lines for transmission.
oNothing shows on the display?
•Is the power plug firmly plugged in?
Check the plug and be sure it is firmly plugged into the socket.
•Cannot solve the problem?
Disconnect the power. Wait five seconds and reconnect the power again.
Check the other party’s fax and be sure that it is compatible with your
FAXPHONE. There are some compatibility problems between certain
types of faxes.
•Still cannot solve the problem?
Call for service.SHARING A TELEPHONE LINE
oFAXPHONE continues to ring.
•If you have only one telephone line, you can set the FAXPHONE to
receive both faxes and voice calls. This is called Fax/Tel Mode (see page
17). When you receive a voice call, you must pick up the telephone
attached to the FAXPHONE. If you pick up another phone attached to the
same line but NOT attached to the unit, the FAXPHONE continues to
ring.
•If you have only one telephone line, the most efficient way to set up your
system is to attach a cordless phone to the FAXPHONE. When the
telephone rings, you can pick up the cordless phone anywhere; you dont
need to be near the FAXPHONE.
•Another alternative is to use a Distinctive Ring Pattern (DRP) service
that may be available from your telephone company. See page 21 for
information on DRP service. 
						

							978Print quality problems
If the printout is unsatisfactory, consider the following suggestions:
zMost paper has a right side and a wrong side. If the print quality is poor, try
turning the paper over and printing on the other side.
zIf characters and images are blurred, check that you are using the correct
kind of paper, see p. 6.
zIf ink gets on the printer’s platen, the reverse side of the printed page will
have smudges. In this case, clean the platen area with a soft dry cloth.
See p. 89.
zIf white streaks or missing dots appear on printed pages, perform the print
head cleaning operation. See p. 90.
zIf the quality is not crisp and clear after cleaning the print head, repeat the
head cleaning procedure again. If output is still not satisfactory after clean-
ing the print head five consecutive times, replace the BJ cartridge. See p. 91.
zIf the following print quality problems occur in the entire printing area,
check for the most probable cause and remedy as listed below.

							1018 In case of a power failure
The user data settings and registered data for One-touch Speed Dialing and Coded
Speed Dialing are saved during a power failure using a built-in battery. However, docu-
ments stored in the FAXPHONE memory will be deleted. If a power failure occurs or
the power is turned off, the FAXPHONE will automatically print a Memory Clear List
as soon as the power is turned on or the power is restored. This list informs you of the
deleted memory files.
During a power failure __________________________
The following restrictions apply to the function of the FAXPHONE during a power
failure or while the power is turned off:
zA call can be received with the FAXPHONE during a power failure. However, a call
cannot be made since the numeric buttons, One-touch Speed Dialing and Coded
Speed Dialing features are not operational.
zA document can neither be sent nor received during a power failure.
