Error in Printhead Drop Detection.
This error code appears when the Printer detects that the same area
of nozzles do not work in different Printheads. The possible causes
are either fibres or a piece of paper in the Drop Detector or that
the Scan-Axis reference is incorrect.
Corrective Action:
Try the following:
-Manually recover the Printheads (See How
to fix the Nozzle Defects) and check whether the error
still appears.
-If the error does appear again, then check that
there no fibres or pieces of paper in the Drop Detector.
-If the error does not appear again, then check
that the Scan-Axis stop of the Carriage is not deformed too much
(some slight deformation of upto 0.5mm is normal, but if it is bigger
than that, then replace the Carriage Assembly and recalibrate the
Printer).
-If the Scan-Axis is OK also, then replace the Drop
Detector Assembly or the Service
Station Assembly and
recalibrate the Printer.
