Print head needs to be cleaned

If the nozzle check page does not print satisfactorily (for example, if any segment of the printed lines is missing), there is a problem with the printer. This could be a clogged ink nozzle or a misaligned print head. See Cleaning the Print Head for details on cleaning the print head. For information on aligning the print head, see Aligning the Print Head.The nozzle check page also indicates the amount of ink remaining in each cartridge. BK: shows the amount of remaining black ink, and CL: shows the amount of remaining color ink.
