ALSO, I HAVE HP 64 CARTRIDGE INSTALLED FOR BLACK, WHICH IS WHAT CAME WITH PRINTER,  HP UTILITY NOW SAYS HP 70 FOR BLACK.  BUT I HAVE BEEN PRINTING FOR 6 MONTHS NO PROBLEMS.

 

NOW ALL OF A SUDDEN BLACK IS NOT SHOWING UP,  I DID CLEAN PRINT HEADS,  DID ALIGN ( WONT ALIGN). DID THE 60 SECOND POWER OFF.

 

COULD IT BE AS SIMPLE AS HP UTILITY IS WRONG AND CARTRIDGE IS E,PTY?
