    Abstract: A printing apparatus includes a media support assembly, a scanning module, and a control module. The media support assembly may position a respective media portion in a print zone to receive a printing fluid thereon. The scanning module may scan the media portion in the print zone and generate a media shape signal corresponding to a shape of the media portion. The control module may compare the media shape signal to a reference signal to form a resultant comparison and determine a media malfunction event based on the resultant comparison.

    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.

    Abstract translation: 一种控制打印机托架的方法，其中当安装在打印机托架上的打印头正在打印区域中喷射打印流体时，打印机滑架被控制成以第一预定速度沿着第一轴线移动。 打印机托架可沿着第一轴沿双向移动，以使打印头能够在打印区域中进行打印。 当打印头不在打印区域中喷射打印流体时，打印机托架也被控制为以第一预定速度高于第一预定速度的第一轴线移动。

    Abstract: Aspects of the disclosure provide an electronic device comprising a controller. The controller to determine a volume of print fluid in a first tank of the electronic device, monitor current printing conditions of the electronic device disposing print fluid on a substrate, determine, based on the volume of print fluid and the current printing conditions, whether an adverse printing condition exists, responsive to the volume of print fluid being less than a threshold and the adverse printing condition not existing, control a pump to refill the first tank from a second tank at a flow rate determined at least partially according to the determined volume, and responsive to the volume of print fluid being less than the threshold and the adverse printing condition existing, control the pump to refill the first tank from the second tank at a default flow rate determined independent of the determined volume.

    Abstract: A method is disclosed. The method may involve obtaining information indicative of a number of printing passes of a print head to print a swath on a printable medium. The method may comprise determining that the print head is to perform a particular printing pass which is one of: a printing pass during which an amount of print agent to be deposited from nozzles of the print head differs, by an amount that exceeds a defined threshold, from an amount of print agent to be deposited from the nozzles during a printing pass immediately preceding said particular printing pass; and a printing pass to print a swath which is the first of a plurality of adjacent swaths in which each swath has an area coverage exceeding a defined threshold. The method may comprise preparing, based on said obtained information, a schedule for a nozzle spitting procedure to commence before the print head performs the particular printing pass.
