The problem is 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 wil not appear. See How do I manage printhead monitoring?.
The problem is 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 How do I change the print quality?.
● Clean the printheads; see How do I recover (clean) the printheads?.
● Use the Image Diagnostics Print to identify which printhead is causing the
problem; see How do I use the Image Diagnostics Print?.
The problem is the printer does not print
Here are some possible explanations. See also The problem is a print job is waiting
for a time-out.
● You may have an electrical power problem. If there is no activity at all from the
printer, and the front panel does not respond, check that the power cable is
connected correctly and that there is power available at the socket.
● In the presence of unusual electromagnetic phenomena, such as strong
electromagnetic fields or severe electrical disturbances, the printer may behave
strangely, or even stop working. In this case, turn off the printer using the Power
key on the front panel, wait until the electromagnetic environment has returned to
