Abstract: Systems and methods for printhead position control. The system comprises a controller that identifies a target distance for moving a printhead in a lateral direction to compensate for lateral shifts in a web of print media as the web travels in a continuous-forms printer in a conveyance direction. The controller also identifies a maximum distance for moving the printhead in the lateral direction based on an allowable print error in a color plane of the printer and one or more previous positions of the printhead. The control further moves the printhead for a distance that is a lesser of the maximum distance and the target distance.

Abstract: A method and a device for monitoring gas sensors in an internal combustion engine, in which in a steady-state operation of the internal combustion engine, the output signal of the gas sensor is filtered by a high-pass filter and higher-frequency signal components are analyzed by a comparison with an appropriately processed model value. When using the method and the device for executing the method, electrically oscillating gas sensors or the incoupling of interference variables or faults in the evaluation circuit, especially in the case of exhaust gas sensors in an exhaust-gas purification and reducing system, are able to be detected, which minimizes faulty interpretations in a dynamic diagnosis. This monitoring function is advantageously combinable with dynamic diagnosis functions that likewise analyze higher-frequency signal components by a comparison with appropriately processed model values. This increases the operational reliability of the exhaust-gas purification or reducing system.
