An imaging apparatus configured for mounting an ink supply cartridge includes a guide frame defining a main scan direction. A printhead carrier for mounting the ink supply cartridge is coupled to the guide frame. The printhead carrier includes a housing cradle. A first latch device is pivotably coupled at a first axis to a front portion of the housing cradle, the first latch device being rotatable between a first latched position and a first unlatched position. A second latch device is pivotably coupled at a second axis to a rear portion of the housing cradle, the second latch device being rotatable between a second latched position and a second unlatched position. The first latch device and the second latch device are configured to define a top opening for vertically receiving the ink supply cartridge between the first latch device and the second latch device.
