  • Publication number: 20190126550
    Abstract: A method comprises switching on a first radiation source of a plurality of radiation sources. The plurality of radiation sources are for delivering radiation towards a print area of a printing apparatus. Each of the plurality of radiation sources may be connected to control circuitry via one of a plurality of circuit terminals. The method may further comprise detecting, using a detector, a change resulting from radiation from the first radiation source. The method may further comprise determining, using a processor, based on the detected change, connection information indicative of the circuit terminal to which the first radiation source is connected.

  • Publication number: 20190118479
    Abstract: In an example, a method includes controlling a drive mechanism (110) of an additive manufacturing apparatus (100) to move a build platform (104) of the apparatus relative a static member (102); monitoring the movement of the build platform (104) using an optical sensor (302) that senses relative displacement between the build platform (104) and the static member (102); and generating calibration data based on the movement of the build platform (104) for calibrating a drive controller (120) of the drive mechanism (110) to compensate for run-out effects in the movement of the build platform.

  • Publication number: 20180281418
    Abstract: In an example, a printhead-wiping device comprises: a wiper element and a biasing mechanism, the biasing mechanism to bias the wiper element towards a printhead. An actuator may be used to adjust a preload force applied to the biasing mechanism. The preload force applied to the biasing mechanism may be controlled using a controller so as to control a wiping force applied by the wiper element against the printhead.

  • Patent number: 9931847
    Abstract: A printer is disclosed herein. The printer has a printhead having a plurality of ink nozzles for ejecting ink, a servicing mechanism for capturing the ejected ink from the ink nozzles, to service the printhead, and a control device coupled to the printhead and the servicing mechanism for regulating the servicing. As part of the regulation, the control device continues feeding a substrate towards the printhead during an idle period. The idle period of the printhead can be a duration when printing on the substrate is suspended. Further, the control device regulates ejection of ink from the ink nozzles towards the substrate during the idle period and operates the servicing mechanism during the idle period. In an example, the servicing mechanism captures the ink before the ink reaches the substrate.

  • Publication number: 20170210136
    Abstract: A printer may comprise a printhead comprising a number of nozzles, an immiscible fluid applicator, and a processor to instruct the immiscible fluid applicator to apply immiscible fluid onto the surface of the printhead to cap the number of nozzles. A printer subassembly may comprise an immiscible fluid applicator to wipe a layer of immiscible fluid onto a surface of a printhead. A printer may comprise a page wide array printhead, an immiscible fluid applicator to wipe a layer of immiscible fluid over a printhead to cap nozzles over the width of the printhead, and a controller to instruct the printhead to print after the layer of immiscible fluid has been applied over the printhead so that ink ejects through the immiscible fluid while non-used nozzles remain capped by the immiscible fluid layer.

  • Patent number: 9427955
    Abstract: A method to control a printer carriage in which the printer carriage is controlled to move along a first axis at a first predetermined speed when a printhead, installed on the printer carriage, is ejecting printing fluid in a print zone. The printer carriage is moveable bidirectionally along the first axis in swaths to enable the printhead to print in the print zone. The printer carriage is also controlled to move along the first axis at a second predetermined speed, higher than the first predetermined speed, when the printhead is not ejecting printing fluid in the print zone.

  • Patent number: 9186890
    Abstract: A method of determining a delay value by an image forming system may include transporting a media along a media transport path by a media transport unit, heating the media by a heating unit, providing a plurality of print passes across the media transport path by a print head assembly, and applying ink to the media to form an image including a plurality of swaths by the print head assembly such that a respective swath is formed on the media corresponding to a respective print pass. The method may also include detecting a temperature of the media by a temperature module to determine whether the detected temperature is outside of a target temperature range, and determining a delay value by a delay determination module in response to a determination that the detected temperature is outside of the target temperature range.
