Printhead Status Messages While Printing

Detailed below are the printhead status messages that may be displayed while printing.
OK
The printhead is operating correctly and will provide an acceptable level of print quality. To find more information on the printheads, refer to Obtaining Printhead Information.
Replace
The Printhead is faulty and needs to be replaced before the printer can continue printing.
If this message continues to appear (for example after installing new Printheads), try the following:
1. Reseat the Printheads and check if the message disappears.
2. Remove the Drop Detector and make sure that there are no obstacles inside which are blocking the sensor.
3. Print the Diagnostic Print. Check that the Printhead nozzles are firing correctly.
5. Replace ALL the Printheads.
