Devices, systems, and methods for printhead cleaning

A printhead-cleaning system comprising:

• a cleaning-fluid-supply reservoir that is configured to store cleaning fluid;
• one or more cleaning-fluid-supply conduits that are configured to connect to the cleaning-fluid-supply reservoir, connect to a printhead while the printhead is installed in a printer, and convey cleaning fluid from the console to the printhead while the printhead is installed in the printer, wherein the printhead includes a plurality of nozzles;
• a first pump that is configured to supply cleaning fluid from the cleaning-fluid-supply reservoir to the one or more cleaning-fluid-supply conduits;
• a cleaning-fluid-collection reservoir;
• a fluid collector, wherein the fluid collector is detached from the cleaning-fluid-collection reservoir, is moveable independent of the cleaning-fluid-collection reservoir, and can be positioned below the printhead while the printhead is installed in the printer;
• a cleaning-fluid return conduit that is configured to connect to the fluid collector and the cleaning-fluid-collection reservoir and that is configured to convey liquid from the fluid collector to the cleaning-fluid-collection reservoir;
• one or more printhead-communication cables that are configured to connect to a printhead and supply electrical signals to the printhead while the printhead is installed in the printer;
• 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 printhead-cleaning system to perform operations including:
• supplying cleaning fluid from the cleaning-fluid-supply reservoir, through the one or more cleaning-fluid-supply conduits, to the printhead while the printhead is installed in the printer, and
• while supplying the cleaning fluid to the printhead, sending one or more signals to the printhead, through the one or more printhead-communication cables, to activate one or more nozzles of the plurality of nozzles of the printhead while the printhead is installed in the printer.
