When to Replace Ink Tank and Maintain Printhead
When an ink tank is empty, it must be replaced.
The BJ Status Monitor (Windows) or the BJ Print Monitor (Macintosh) will initially advise 
you of a low ink level. At this stage, you can still continue to print.
Once an ink tank is empty, the BJ Status Monitor (Windows) or the BJ Print Monitor 
(Macintosh) will tell you to replace the ink tank. Attempting to print causes the POWER 
lamp to flash four times.
If printing becomes faint or a specific color is no longer printing, even though there is still 
enough ink, the printhead nozzles are probably clogged. Follow the procedures below to 
clean the nozzles.
If the print quality is poor
If the problem remains
If printhead deep cleaning does not resolve the problem, the printhead may be worn out.
