2 new Maintenance Cartridges put in but the message won't go away. No ink had been ejected into them. The printhead was also replaced because the machine said to. Afterwards, got test prints that were not printed correctly. Currently, test prints are blank.

When running 'cleaning', 'nozzle check' appears a few times, then says 'Hardware Error 03800500-2F30'. I see on another post the problem was the Flexible Cable.
Has anyone seen this problem? Thanks
