Error light
If the ERROR light on the console lights up:
• The called party is disconnected or has not
responded or
• The called fax machine is incompatible
with your DF450 or
• Errors have been detected during
transmission/reception.
To switch off the
ERROR light, press the
STOP button.
To reset your DF450
If you encounter a problem and your DF450 will
not respond to any button presses, turn the
power switch off for ten seconds. Turning the
power back on will reset your DF450 to standby
mode. Your personalised settings and memorised
numbers will be maintained.
Document memory
If your DF450 runs out of ink or paper while
receiving a fax, the document will continue to be
received and stored in your DF450’s memory, to
be printed out when ink/paper is replenished. No
further documents can be received until the
ink/paper is replenished and the documents
stored in the memory have been printed. The
maximum storage capacity is about ten pages of
the industry standard test sheet (shown on page
39).
The capacity may be less depending on the
document content.
In the event of power failure, the data retained in
the document memory will be maintained for
several hours.
Print cartridge life
The replacement ink cartridge contains sufficient
ink to produce 500 copies of the industry standard
test sheet (shown on page 39, which has about 6%
black on white coverage of an A4 sheet).
If your average black on white coverage exceeds
this standard then, the number of printed sheets
will be reduced.

No dialling tone when using monitor button
Is your DF450 line cord plugged into the
phone socket? Ensure that the speaker volume is
not set to the minimum (see page 25).
Poor print quality
If there is a problem with the quality of a fax you
have sent, or a document you have copied, the
optical scanner may need cleaning (see “Cleaning
the optical scanner”, page 35).
