摘要： The disclosed embodiments illustrate a thermal printer apparatus that includes a media sensor. The sensor generates an input signal indicative of a measure of a media transmissivity/reflectivity. Further, the thermal printer includes a processor that is configured to receive the input signal from the sensor, while the media is stationary with respect to a print head. The processor further determines one or more characteristics of the input signal. Thereafter, a first transmissivity/reflectivity threshold is determined based on the one or more characteristics in the input signal. Further, the processor receives the input signal from the sensor, while the media traverses with respect to the print head. Subsequently, the processor determines one or more current characteristics of the input signal while the media traverses with respect to the print head. A media jam condition is detected based on the one or more current characteristics and the first transmissivity/reflectivity threshold.

摘要： A method for evaluating a print quality of a printed document that is printed by a printer is provided. The printer comprises a pre-print image scanner, a post-print image scanner, and a printhead disposed between the pre-print image scanner and the post-print image scanner. The method comprises generating a pre-printing image of a print media, generating the printed document, generating a post-printing image of the printed document, generating a validation image by comparing the post-printing image with the pre-printing image, and comparing the validation image with the source image.

摘要： An apparatus and method for automatically calibrating a media sensor configured to detect advancing print media in a printing device. In some embodiments, the apparatus selects a first light intensity level and a second light intensity level greater than the first light intensity level. A light source unit, such as a light emitting diode or laser diode is activated to emit light at the second light intensity level. The light passes though print media, for example, a roll of self-adhesive labels, that is advanced along a print path of the printing device. The amount of light transmitted through the print media is measured as the print media advances. If the measured light increases, the light source unit is reactivated to emit light at the first light intensity level. In some embodiments, the apparatus identifies whether print media has changed or an out-of-stock condition exists.
