1 DO NOT replace any parts. . Remove the
Printheads and clean the flex contacts on the Carriage and the Printheads. Reseat the
Printheads and try the test again.
2 Even if one of the Printheads failed the Printhead Continuity test, you must remove the
Printheads from the Carriage and try installing them . Before installing each
Printhead, check the continuity of all four Printheads. The frontĆpanel should display a
3ffff / 3fff result for each Printhead that is not inserted and the original values (the value
that was displayed before the Printhead was removed) for the Printheads when they are
inserted. If you get a value that is different than 3ffff / 3fff when the Printheads are
removed then you must perform step again. If you get the same results after repeating
step 1, then the carriage is damaged. Replace the Carriage Assembly. When you insert each
Printhead, the values for that Printhead. If the values of other
Printheads also change, then the problem is the Printhead itself and the actual Printer.
In this case you replace the complete Ink Delivery System of the color that failed.
3 If you continue getting the original value (the value that was displayed before the
Printhead was first removed) then you replace the complete Ink Delivery System of
the color that failed and try the test again.
4Asa , replace Carriage Assembly.
