  • Patent number: 10245854
    Abstract: In one example, a printer having a removably-installable platen. The platen has a platen type. A surface of the platen has a feature that is indicative of the platen type. The printer includes a single platen-type-discriminating sensor. The sensor detects a distinguishing characteristic of the feature. A controller determines the platen type from the distinguishing characteristic.

  • Publication number: 20190092060
    Abstract: A device (2) includes a media roll (4) to output a print medium (M) in a forward direction (26) and a wiper roll (6) to contact the surface of the print medium (M) at a rotation speed to cause friction on the print medium (M). The device (2) may determine a radius (r2) of the media roll (4) outputting the print medium (M) and, based on this radius (r2), adapt parameters such as the rotation speed of the wiper roll and a back tension (T2) exerted by the media roll (4) on the print medium (M) so as to control the friction caused by the wiper roll (6) on the print medium (M).

  • Publication number: 20180104970
    Abstract: An example printing apparatus is described comprising a wiping element before the print zone, for slipping in contact with a print medium and wiping a printing surface of the print medium. An implementation of a wiping roller for wiping the printing surface of a print medium may comprise a rigid core, a layer of elastic material and a driving pinion. An example method for printing is also described, comprising spreading over a larger print medium area, by wiping, amounts of a substance that may migrate through a print medium and that is present on the printing surface of a print medium, before printing on the print medium.

  • Patent number: 9108435
    Abstract: Registering images during two sided printing is disclosed. An example is carried out by program code stored on non-transient computer-readable medium. The program code is executable by a processor for printing on a first side of a media a first plurality of plots and a plurality of associated fiducials along an edge of the media. The program code is executable by a processor for determining a distance from the edge of the media to at least one of the plurality of associated fiducials based on sensed input. The program code is executable by a processor for printing a second plurality of plots on a second side of the media based on the distance from the edge of the media so that the second plurality of plots is substantially in registration with the first plurality of plots.

  • Patent number: 8817317
    Abstract: In one embodiment, printing, on a first side of a media, of a first plurality of plots and a plurality of associated fiducials is caused. For each of a second plurality of plots, using data from a sensor, a distance to one of the plurality of associated fiducials is measured to discern a reference for printing that plot on a second side of the media. Printing of the second plurality of plots on the second side is caused so that each of the second plurality of plots is substantially in registration with one of the first plurality of plots.

  • Patent number: 8123327
    Abstract: In one embodiment, a distance that a target moves is calculated utilizing an optical sensor. A first temperature of a first portion of the optical sensor is measured at the time of the distance calculation. A second temperature of a second portion of the optical sensor is measured at the time of the distance calculation. The distance is adjusted by a compensation factor that is a function of the first and second temperatures.
