Dial Tone detection
B
When you send a fax automatically, by
default your machine will wait for a fixed
amount of time before it starts to dial the
number. By changing the Dial Tone setting to
Detection
you can make your machine dial
as soon as it detects a dial tone. This setting
can save a small amount of time when
sending a fax to many different numbers. If
you change the setting and start having
problems with dialling you should change
back to the factory
No Detection
setting.

If you are having problems sending or
receiving a fax due to possible interference
on the phone line, we recommend that you
adjust the Equalization for compatibility to
reduce the modem speed for fax operations.

Routine maintenance

Replacing the ink cartridges
B
Your machine is equipped with an ink sensor.
The ink sensor automatically monitors the
level of ink in each of the 4 cartridges. When
the machine detects an ink cartridge is
running out of ink, the machine will tell you
with a
Near Empty
message on the LCD.
The LCD will tell you which ink cartridge is low
or needs replacing. Be sure to follow the LCD
prompts to replace the ink cartridges in the
correct order.
Even though the machine tells you that an ink
cartridge is empty, there will be a small
amount of ink left in the ink cartridge. It is
necessary to keep some ink in the ink
cartridge to prevent air from entering the print
head assembly.
a
Open the ink cartridge cover.
If one or more ink cartridges are empty,
for example Black, the LCD shows
Ink Empty Black
and
Replace Ink
.
b
Pull the lock release lever down and
take out the ink cartridge for the colour
shown on the LCD.
