2-2 Using BJ Cartridges Chapter 2
If Printing Is Unclear or Colors Are Missing
If your printing is unclear or colors are missing, one of the following may be the reason:
The BJ cartridge print head nozzles are clogged.
An ink tank is empty.
If printing becomes unclear or colors are missing, print the Nozzle Check Pattern to
determine whether each nozzle in the print head is operating correctly. If the print head is
clogged, perform the print head cleaning procedure. If the print head is operating
properly, replace the ink tank.
Printing the Nozzle Check Pattern
Make sure paper is loaded in the paper supply tray.
Important! Paper must be loaded in the paper supply tray! You cannot print a
Nozzle Check Pattern when using manual paper feed. The paper in the manual
feed slot will be ejected.
If the printer is on, turn it off.
Press and hold the POWER button until you hear four beeps, then release
the button.
The printer loads paper and prints the Nozzle Check Pattern. (If the printer has
not been used in awhile, the printer cleans the print head before loading paper.)
