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

To eliminate this message, choose one of the following:
●
Select a higher print quality; see
Change the print quality on page 57.
●
Clean the printheads; see
Recover (clean) the printheads on page 97.
