Blown fuse - new fuse and printhead will not stop firing on test print - any ideas - tried a old printhead and the problem was the same - swap cables and problem stays with the printhead - thanks Scott

it's not just a "swap cables" in order to prove it the carriage board port vs the head you need to do a "data swap". if the band of ink follows the head the head is bad, if the issue follows the data ribbon (via port) the board needs repaired. (don't buy carriage boards, have macmedia fix them).
