ABSTRACT:
A method of priming a printhead cartridge upon installation in a printer, the printhead cartridge having a printhead with a nozzle face defining an array of nozzles for ejecting ink on to a media substrate fed past the printhead in a media feed direction, by providing a printer with at least three ink tanks for storing the inks of different color, the printer also having a cradle for supporting the printhead cartridge adjacent a media feed path, a fluid interface in fluid communication with the ink tanks, and a latch for securing the printhead cartridge in the cradle, the latch being movable between an open position where access to the cradle is unobstructed, and a closed position where access to the cradle is obstructed, placing the printhead cartridge in the cradle while the latch is in the open position, the printhead cartridge having a fluid coupling positioned to align with the fluid interface when placed in the cradle, moving the latch to the closed position to secure the printhead cartridge in cradle, providing a mechanical linkage between the latch and the fluid interface such that the fluid interface sealingly engages the fluid coupling upon moving the latch to the closed position and, priming the printhead with ink from all of the ink tanks.
