Abstract
Printing systems are disclosed for preventing sediment buildup. In one implementation, a printing system is provided. The printing system includes a print area and a print head housing configured to enclose a print head spaced from the print area. The print head has a plurality of nozzles for expelling a printing liquid therefrom. The printing system further includes a pipe for interconnecting the print head with a reservoir, a pump for circulating the printing liquid from the reservoir to the print head and through the plurality of nozzles, and a processor. The processor may cause the pump to circulate the printing liquid to the print head and through the plurality of nozzles during a period of non-printing. In one embodiment, circulating the printing liquid includes flowing the printing liquid from the reservoir to the print head and from a retainer located below the plurality of nozzles back to the reservoir.
