The invention is directed to a process for priming a
multi-chamber ink jet print head the nature of which is
apparent from an analysis of representative independent claim

1. A process for priming a multi-chamber ink jet print
head having an array of nozzles and an ink associated with
each chamber in fluid communication with said nozzles, said
process comprising the steps of:
positioning a resilient seal around the venting portion
of the print head;
positioning the nozzles so that said nozzles are elevated
in the vertical position above the ink; and
applying pressure to the vent side of the resilient seal
so that each chamber of the print head is pressurized and ink
is forced through the nozzles.
