Print head needs to be cleaned
|
If the nozzle check page does not print satisfactorily, 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. The percentages that appear on the nozzle check page will reflect an approximate value.
