1. A device comprising:
a cleaning-fluid-supply reservoir;
a cleaning-fluid-supply conduit;
one or more electrical connectors that are configured to be attached to a printhead and supply electrical signals to the printhead;
one or more memories; and
one or more processors that are in communication with the one or more memories and that cooperate with the one or more memories to cause the device to perform operations including:
supplying cleaning fluid from the cleaning-fluid-supply reservoir, through the cleaning-fluid-supply conduit, to the printhead, and
while supplying the cleaning fluid to the printhead, sending a signal to the printhead, through the one or more electrical connectors, to activate one or more piezo-electric actuators of the printhead to eject the cleaning fluid through one or more nozzles of the printhead.
