A media handling system for delivering media sheets to be printed from a staging location to a drum along a media path, including: at least one drive roller positioned along the media path between the staging location and the drum; a sensor positioned along the media path between the at least one drive roller and the drum; and, an encoder that provides an output responsive to the sensor; wherein, when the at least one drive roller advances a media sheet from the staging location to engage the drum, the sensor detects a position of the advancing media sheet prior to engaging the drum, and the rate of further advancing of the media sheet to engage the drum by the at least one drive roller is dependent upon the encoder output.

Media handling system and method

In one embodiment, a system and method pertains to detecting a position of a sheet of media that has been loaded onto the print surface, determining from the detected position a current loading error with which the media sheet has been loaded onto the print surface, and calculating a loading offset that can be used to adjust the position at which a future media sheet will be loaded onto the print surface.

Systems and methods for adjusting loading of media onto a print surface

A first position of a media is determined with respect to a surface. The surface is advanced and a second position of the media is determined with respect to the surface. The relative speed between the surface and a linear speed feed of the media is altered based on the first and second positions.

Feeder speed

In one embodiment, a system and method pertain to measuring the length of media using a first sensing system of the printing device to obtain a first length value, measuring the length of the media using a second sensing system of the printing device to obtain a second length value, and calculating a scale factor that can be applied to measurements made by the first sensing system to increase the accuracy of those measurements, wherein the scale factor is calculated relative to the first and second length values.
