The printhead side (30) of the carrier (22) defines ink supply formations and passages in fluid communication between the ink supply formations and one of the feed formations. A cover (78) is engageable with t he carrier (22) at the ink supply side (28) and is shaped to define a roof for the feed formations (60) and defines ink pathways (86) in fluid communicatio n with respective feed formations (60).
