Phone line interference

B

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

B

Replacing the ink cartridges

B

Your machine is equipped with an ink dot 
counter. The ink dot counter 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 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 drying out and 
damaging 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

 and 

Black

.

b

Pull the lock release lever down and 
take out the ink cartridge for the color 
shown on the LCD.
