摘要:
A deviation correcting system for a scanner including a central processing unit producing a control signal for reading out a correcting program for correcting a scanning deviation, and a test pattern, for printing the test pattern, for scanning the printed test pattern, and then for correcting a scanning deviation; a print driver producing a control signal for printing the test pattern produced from the central processing unit, feeding the test pattern back to a scanning position; a printing unit printing the test pattern and then feeding the test pattern back to the scanning position upon application of the control signal from the print driver; an image processing unit producing a control signal for scanning the test pattern upon application of the control signal from the central processing unit; and a shuttle scanner module scanning the test pattern and producing image data upon application of the control signal from the image processing unit.

A sheet-size-determining device in a scanner, includes: a sheet carrier, having a pattern formed across the entire surface thereof, for holding (loading) a sheet of printed medium; a paper feeding device for controlling the feeding operation of the sheet carrier; a shuttle scanner module for scanning image data of the sheet of printed medium and outputting the scanned image data; a carriage return motor for driving the shuttle scanner module; an image memory for temporarily storing the scanned image data output from the shuttle scanner module; and a controller for analyzing the temporarily stored image data and outputs a control signal to the carriage return motor according to the analysis. The sheet carrier includes a background panel having a pattern formed thereon and a transparent flap connected to the background panel along one edge thereof.
摘要:
A device and a method for using a temperature detector to detect heat generated from the lamp of a scanning device to prevent the operation of a scanner while the scanner is overheating. Thus, effectively preventing the degradation of a scanner due to the overheating of the lamp in the scanning device of a multi-function peripheral. In addition, when the lamp becomes overheated, a safety margin can be maintained even when the central processing unit is not operating properly, because the power of the lamp gets cut off compulsorily through hardware rather than software that is necessarily dependent on the central processing unit.
