Abstract:
1. A printer with a malfunction-diagnosis system, the printer comprising a printing unit arranged to produce a printout from image-representing data, an input device arranged to receive printer-operation-related input from a user, an output device arranged to provide printer-operation-related information for the user, a printer controller arranged to control operation of the printer in response to input commands by the user from the input device and to forward the image-representing data to the printing unit and to output the printer-operation-related information for the user at the output device, and at least one sensing device arranged to perform measurements on the printout produced by the printing unit and to output corresponding measurement data to the printer controller, wherein the printer controller further is configured to initialize a malfunction diagnosis by receiving an indication of a user perceived print quality defect from the input device, generate image data representing a test print job in response to the received indication of the user perceived print quality defect, and to forward the test print job image data to the printing unit to produce a corresponding test printout, receive and analyze the measurement data output from the sensing device as measured on the test printout, and output information indicative of a cause for the print defect based on an analysis of the measurement data output from the sensing device.
