Replacing a BJ Cartridge
Replace a BJ Cartridge only after you have cleaned the print head and
determined that the BJ Cartridge is not operating correctly based on the
results of the Nozzle Check Pattern. (☞ 97) If the Nozzle Check Pattern is
abnormal and none of the ink tanks is empty, replace the BJ Cartridge.
1 Check the Nozzle Check Pattern to see which print head is not operat-
ing properly.
If the colour patterns are not normal, the colour BJ Cartridge on the
right must be replaced.
If the black patterns are not normal, the black BJ Cartridge on the left
must be replaced.
2 Open the top cover.
3 Press the REPLACE button. The cartridge holder moves to the left side
of the printer.
