Abstract

A cradle assembly for a pressure decay leak tester is provided. The assembly operatively receives a printhead integrated circuit carrier having a plurality of printing fluid paths defined therein, respective fluid inlets in fluid communication with respective fluid paths and a locating formation to facilitate correct location of the carrier on the tester. The assembly includes at least one complementary locating formation for engaging the locating formation of the carrier, and at least one fluid outlet for charging the carrier with fluid via a respective fluid inlet of the carrier. Also included is a clamping device for clamping the carrier to the fluid outlet, so that the integrity of the fluid paths is observable via pressure decay testing, and a control system operatively connected to the clamping device for controlling operation of the clamping device.
