  • Publication number: 20210014379
    Abstract: A duplex printing method includes, determining an amount of shrinkage of a media sheet onto which a front side image has been printed; scaling an image to be printed on a back side of the sheet with a scaling function that depends upon the determined shrinkage; and printing the scaled image on the back side of the sheet. The step of determining includes predicting a shrinkage of a media sheet on the basis of process parameters, and on the basis of a model that is defined by a set of model parameters and that describes a dependence of the shrinkage on the process parameters, the process parameters including at least an amount of marking material to be applied to the front side of the sheet; measuring an actual shrinkage of the sheet; and adjusting the model parameters based on a comparison between the predicted shrinkage and the measured shrinkage to improve a prediction of a shrinkage for a subsequent sheet.

  • Patent number: 10391794
    Abstract: A duplex sheet printer comprising a first and second sheet quality detection device for determining a suitability of a sheet for printing. The first sheet quality detection device applies a first sheet rejection threshold to which sensed sheets are compared, while the second sheet quality detection device applies a second sheet rejection threshold different from the first. The controller designates sheets in the printing system to be sensed by one of the sheet quality detection devices in accordance with the sheet's media type or the sheet being on a simplex or duplex pass. Different rejection criteria are thus applied to the sheets without adjustment of a sheet quality detection device, resulting in high speed printing.
