Printhead Recovery Procedure
The Printer regularly performs a series of controls on the health of
the Printheads and when they start to degrade the Printer will
prompt the user to recover the Printhead [(XX20)Recover].
At this stage, the customer should obtain new Printheads.
Depending on the print mode being used (Max. Quality,
Productivity or Max. Speed) the Printer may still be able to print
with an acceptable print quality. Refer to Page 6-15 for details on
performing Printhead recovery.
If the Printer is printing a job and the Printhead health degrades to a
significant degree [(XX16) and (XX17)
REPLACE], the front panel
will display a warning.
Press the ↓ or ↑ down key to select YES or NO and press the Enter
key. If you select YES the print job will be cancelled and Printhead
replacement will be started. If you select NO, the Printer will finish
the current print job.
NOTE This message will be displayed each time you send a print job to
the Printer until you replace the failing Printhead(s).
WARNING If you select NO the Printer finishes the current print job
WITHOUT using the failed Printhead i.e. without using that
color.
