A consumable supply item for an imaging device holds an initial or refillable volume of ink. A housing defines an interior having a pair of opposed electrodes. The electrodes have a capacitance that varies in response to an amount of liquid between them. A controller energizes one electrode and receives an output reading from the other. The controller processes the reading on board the housing and supplies it as a digital data stream to the imaging device during use. A memory stores calibration values for an empty and full housing. The controller writes back to the memory present fluid levels obtained from the output reading of the electrode. An enable output allows operation or not of a fluid pump in the imaging device. Materials, construction, modularity, and fluid communication ports are further embodiments, to name a few.

Ink use amount evaluation apparatus and method, and inkjet apparatus

Номер: US20130128286A1

Принадлежит: Fujifilm Corp

When image is formed by a liquid ejection head, input image data is subjected to conversion processing including tone conversion using a first look-up table (LUT) and density correction or non-uniformity correction in nozzle units using second LUTs. Ink use amount in image formation is predicted from reduced image data which is generated from the input image data. In this, the calculation is made more efficient by applying a third LUT which is compiled according to requirements from the second LUTs, to the reduced image data, rather than using the second LUTs directly. Since the image conversion processing is carried out which combines the first LUT for tone conversion and the third LUT corresponding to the non-uniformity correction, and the ink amount distribution data is calculated from the reduced image data after the conversion, then it is possible to ascertain an accurate ink amount which reflects the image adjustment conditions.
