  • REFILL SYSTEM AND METHOD
    Publication number: 20220410576
    Abstract: A fluid supply device includes a variable fluid volume to contain a supply of fluid and a variable gas volume to receive pressurized gas to pressurize the supply of fluid. A method of monitoring the fluid supply device may include controlling a gas pressure of the pressurized gas to feed the fluid from the fluid volume, the gas pressure varying in a plurality of pressurization cycles; monitoring a parameter of the pressurization cycles; and determining a change in fill state of the fluid volume as a function of the monitored parameter.

  • Printing fluid container
    Patent number: 10471724
    Abstract: An example printing fluid container (100) comprising a container body (102) defining a cavity (104), and a piston (106) located within the cavity (104), is described. The piston (106) divides the cavity (104) into a first chamber (108) to receive printing fluid and a second chamber (110), fluidically isolated from the first chamber (108), to receive a positively pressurized fluid.

  • PRINT DEVICE WITH VALVE IN PRINT FLUID SUPPLY PATHWAY
    Publication number: 20190070860
    Abstract: In one example, there is disclosed a print device 100 comprising: a print fluid supply pathway 102 extending from a reservoir inlet 104 to a printhead outlet 106; a valve 108 in the print fluid supply pathway 102 downstream of the reservoir inlet 104: a pressure sensor 110 to monitor print fluid pressure upstream of the valve 108; a pressure sensor controller 112 to temporarily close the valve 108 for a closed period and monitor print fluid pressure using the pressure sensor 110 during the closed period; and a print operation controller 114 to control printing operations of the print device 100 so that in use a printing operation continues and print fluid is discharged from a printhead 234 during a closed period of the valve 108 in the respective print fluid supply pathway 102.
