Printhead Status Messages While Printing
Detailed below are the printhead status messages that may be
displayed while printing.
OK The printhead is operating correctly and will provide an acceptable
level of print quality. To find more information on the printheads,
refer to page 3-9, Obtaining Printhead Information.
Ready/Replace The front panel displays Ready and the printhead status is
REPLACE. The printer is giving an early warning that there may be
a degradation of print quality. The Printer has detected more than 4
black nozzles or 7 color nozzles out in 5 out of every 8 servicing
procedures.
A new printhead should be bought. Depending on the print mode
you are using (best, normal or draft) you may still be able to print
with an acceptable print quality, there may be however, a slight loss
in speed. Refer to the table below for more details.
The printer can still operate with a printhead that needs replacing.
The front panel will display:
