"Our 1055CM is leaking badly at the print head and over the head cleaners. Some times it'll make it through one poster before it pukes up a bunch of cyan or black on the poster & all over the head cleaners. "
It is possible the print head valve (inside the print head) is not working and pressurized ink is present while it is printing. This will cause a virtual ink leak. If you replace the print head and the loose ink is still present, replace the ink tube system.
