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 on page 97 .
A “printheads are limiting performance” message
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 on page 57 .
● Clean the printheads; see Recover (clean) the printheads on page 97 .
● Use the Image Diagnostics Print to identify which printhead is causing the problem; see How do
I... (Image Diagnostics Print topics) on page 117 .
