SYSTEM AND METHOD FOR PRESERVING INKJET OPERATIONAL STATUS DURING LONG PERIODS OF PRINTER INACTIVITY

The printhead maintenance station includes a printhead cap having an opening, a printhead vent blocking member configured to block manifold vents in the printhead when the printhead engages the printhead vent blocking member, and a valve. The valve is positioned within the printhead cap to enable the printhead cap to hold a volume of high pH fluid entering the printhead cap through the opening in the printhead cap when the valve is closed and to enable egress of the high pH fluid when the valve is opened. A printhead is lowered onto the printhead cap and a vacuum applied to an ink supply line to the printhead to inject the high pH liquid into the printhead.
An inkjet printer uses ink supply containers that includes bladders for holding waste fluids produced by printhead maintenance stations. The bladders are connected serially or in parallel to the output ports of the printhead maintenance stations to store waste fluids within the bladders of the ink supply containers. As the ink supply containers are depleted of their supply ink, they are replaced and new ink supply containers having bladders within them are installed to renew the capacity of the printer to store waste fluids. In two embodiments, the need for a waste fluid reservoir is eliminated and in a third embodiment, the operational life of a waste fluid reservoir is extended. In all of these embodiments, the production of plastic waste by the printer is reduced.

PREDICTION OF REMAINING USEFUL LIFE OF AN ASSET USING CONFORMAL MATHEMATICAL FILTERING
A system determines that an asset of an engineering system has transitioned from a quasi-steady degradation stage to an accelerated degradation phase based on sensor measurements received from an asset. During the accelerated degradation phase, features are extracted from the sensor measurements that are indicative of wear of the asset.
