Abstract:
According to one example, there is provided a printing system. The printing system comprises a print engine to print a print job on media in a print zone, a heating module to apply heat to media in a heating zone and a media handling system to move media through a media path comprising the print zone and the heating zone. The system further comprises a controller to determine when a printing operation is stopped, and when it is so determined to control the heating module to stop heating and to control the media handling system to continue advancing media through the media path until a predetermined condition is met.
Abstract:
Ink drying apparatus and method for controlling ink drying apparatus are described herein. An example ink drying apparatus includes first and second heating elements positioned adjacent a drying area in a printer, and a controller to determine a temperature of the heating area and to selectively operate, based on the temperature determination, the first heating element in a burst mode and the second heating element in an on/off mode.
Abstract:
A method of determining an angle between a first direction of movement of a print head and a second direction of movement of a print media, comprises: printing an array of markings on said print media, said array of markings extending along said first direction and along said second direction; traversing a sensor device along said first direction, and detecting a signal corresponding to said plurality of markings; identifying a plurality of peaks in said sensor signal as a plurality of data co-ordinates; and obtaining an angle data describing an angle between said plurality of data co-ordinates and a reference data.
Abstract:
A method of determining a registration offset in a hard copy apparatus, the apparatus comprising a pen arranged to mark a print medium and a sensor arranged to detect marks on the medium along a sensor path, the method comprising the steps of: marking a alignment pattern on the medium, the pattern being at least partially located along the sensor path; detecting the position along the sensor path of a portion of the pattern; and, determining a distance by which the pattern is offset from the sensor path in a direction substantially perpendicular to the sensor path, the pattern being configured such that the detected position is indicative of the offset distance.
Abstract:
A system for adjusting measurements is disclosed. In one embodiment, the system includes an optical sensor having a window marked with two fiducials and at least one processor coupled to the optical sensor.

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.
