Abstract: A print medium with encoded data and a print media detection system for use in detecting at least one characteristic of the sheet of print medium based on the encoded data are disclosed. The encoded data is designed to minimize its visual perceptibility. The print media detector is designed to recognize various characteristics of print media based upon the encoded data and transmit information regarding these characteristics to a printing device so that one or more operating parameters of the printing device can be adjusted to help optimize print quality for the particular characteristics of a particular print medium. A printing device including the print medium and print media detection system is also disclosed. A method of detecting one or more characteristics of print media used in a printing device is additionally disclosed. Further characteristics and features of the print medium, print media detection system, printing device, and method are described herein, as are examples of various alternative embodiments.

Abstract: Overall print quality is improved via a method whereby an actual image is printed, a virtual image is defined based on image data, and the actual and virtual images are compared to identify a printhead error pattern which may be used to correct subsequent printing errors. This typically is accomplished via a system which employs an optical device which views an actual image to produce optical data, and a controller which derives a virtual image from image data provided to the printhead. The controller then compares the actual and virtual images to identify an error pattern, and modifies subsequent image data to compensate for perceived errors.

Abstract: A print media preheating method and apparatus uses heat, vacuum, and mechanisms for drying and flattening a sheet prior to ink-jet printing thereon. Pre-shrinking the media, driving out and substantially reducing inherent moisture content prior to depositing wet ink thereon provides greater flatness in the print-zone whereby ink-jet print quality is improved.

Abstract: A monitoring system monitors a pressure wave developed in the surrounding ambient environment during inkjet droplet formation. The monitoring system uses either acoustic, ultrasonic, or other pressure wave monitoring mechanisms, such as a laser vibrometer, an ultrasonic transducer, or an accelerometer sensor, for instance, a microphone to detect droplet formation. One sensor is incorporated in the printhead itself, while others may be located externally. The monitoring system generates information used to determine current levels of printhead performance, to which the printer may respond by adjusting print modes, servicing the printhead, adjusting droplet formation, or by providing an early warning before an inkjet cartridge is completely empty. During printhead manufacturing, an array of such sensors may be used in quality assurance to determine printhead performance. An inkjet printing mechanism is also equipped for using this monitoring system, and a monitoring method is also provided.
