The printer performs a drop detection and displays the drop detector values on the Front Panel.
5. Press OK to accept the values and pass the test or Cancel to reject the values and fail the test.
NOTE: The drop detector values for nozzles out should be below 150 nozzles per printhead.
If they are not print the “2.4.1 Print test plot” and verify that this printhead has so many nozzles
out. If the Printhead has many nozzles out, and it is causing banding, change the printhead. If
the printhead is ok this would indicate an error with the drop detector. Perform the “5.5.2 Drop
Detector Calibration and the “1.5.1 Force Drop detection” procedures.
