A “printhead monitoring” message
This is not an error message. The message is displayed whenever the Printhead monitoring option
is set to Intensive. If you change the setting to Optimized, the message will not appear. See
Manage printhead monitoring.

This message appears on the front panel during printing when the printer has detected that one or
more printheads are not performing optimally, and so it needs to make extra passes to maintain print
quality. To eliminate this message, choose one of the following:
●
Select a higher print quality; see
Change the print quality.
●
Clean the printheads; see
Recover (clean) the printheads.
