MANAGING THE INK CARTRIDGES
Print Cartridge Nozzle Test
You should test the print cartridge when the print is not clear or image
information is missing. The problem may be caused by blocked nozzles on
the ink cartridge.
The nozzle test cleans the ink cartridge by purging the nozzles. Then it prints
a test so you can see the results. Use the nozzle test:
•
When you suspect the nozzles are clogged.
•
When characters are not printing completely.
Cleaning the Print Heads
To clean the print head using your WorkCentre
The Clean Head procedure cleans the print nozzles and removes any
deposits that may impair printing functions.
To run the Clean Head Procedure:
1. Press the Menu
button, then press the 1 + 2 buttons on the keypad.
Then press the Start
button. The display indicates SELF TEST ?.
2. Press the Up
button. CLEAN HEAD ? appears in the LCD display.
3. Press the Start
button. PRINTING... appears on the LCD display.
The WorkCentre 490cx prints a head cleaning test pattern. Notice the series
of diagonal lines across the top and bottom of the test pattern. Breaks within
a line of the same color indicate a clogged nozzle. Try running the Clean
Head procedure again if you see breaks in the diagonal lines.
