Go to Ebay & buy a set of remanufactured #11 printheads for about $45... no firmware updates or bababa...

 

I just repaired 2 DJ500 42" model last week with these perfectly.

if you still have old printhead what happens when you put it back in the printer?

 

Contacts on new printhead are cleaned?

Since you updated firmware that fixes a problem with dates on printheads, you might have defective printhead.

 

Do you have proof of purchase, can you contact your dealer and ask for the warranty claim on a printhead, you might have defective printhead.
