| 1. An ink priming system for an inkjet printhead, the system comprising:
a priming inlet of the printhead for receiving a supply of priming ink;
an ink flow passage interconnecting the printhead and an ink storage compartment; and
a bypass flow passage interconnecting the ink flow passage and the ink storage compartment, the bypass flow passage incorporating
a depressible region provided in a wall of the bypass flow passage which is depressible to open or close the bypass flow passage,
wherein the priming ink flows from the printhead to the ink storage compartment via the ink flow and bypass flow passages
to prime both the printhead and the ink storage compartment with ink simultaneously.
