No. There is no pump in between the ink cartridges and print head. There is
only one pump assembly. The pump is connected to the cap assembly. When the
cap assembly is pushed up against the bottom of the print head it creates
an air tight connection. The suction action of the pump will suck air and
ink through the print head, damper, tubing and ink cartridges.
