  • Patent number: 10500864
    Abstract: In an inkjet printing apparatus, a controller causes a scanner to read an image formed on an original in response to reception of a copy instruction and generates image data representing the read image. The controller determines a standby period in response to reception of the copy instruction. In response to elapse of the standby period since the reception of the copy instruction, the controller separates a cap and an inkjet head. After the cap and the inkjet head separated each other and completion of reading at least part of the image on the original, the controller causes the recording head to eject ink droplets based on the image data.

    Abstract: An embodiment of this invention is directed to a leakage detection of a printhead. The embodiment executes leakage detection as follows in a printing apparatus which uses a reciprocally movable printhead. That is, the embodiment monitors a voltage appearing on a second power line which supplies, to the printhead, a second voltage that is used for detecting the current leakage from the printhead and is lower than a first voltage to be supplied to perform printing by the printhead through a first power line to which a capacitor is parallel-connected. If a timing at which detection of the current leakage is executed is detected, the embodiment performs control so as to execute detection of the current leakage based on the monitored voltage, by turning off supply of the first voltage and turning on supply of the second voltage.

  • Patent number: 8894180
    Abstract: A wiping assembly includes a pair of guide elements located at opposite ends of a headland region of a fluid ejection assembly to extend in a second orientation generally perpendicular to a first orientation through which the opposite ends extend. Each guide element includes at least one first portion and a second portion. The at least one first portion selectively receives biased releasable engagement from a non-wiping portion of a wiping element extending along the first orientation to cause a wiping portion of the wiping element to be in generally parallel relation to, and spaced apart from, the headland region. The second portion causes the non-wiping portion to no longer be in biased releasable engagement against the guide element and causes the wiping portion to be biased in wiping relation against the headland region.
