US 2022/0176703 A1 · DEVICES, SYSTEMS, AND METHODS FOR PRINTHEAD CLEANING AND DIAGNOSTICS

Abstract

Some embodiments of a device comprise 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. Also, the one or more processors cooperate with the one or more memories to cause the device to perform operations that include 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.
