Abstract:
A sheet feeding device comprising a sheet feeding mechanism having a feed motor for feeding sheets and a drive-controller for drive-controlling the feed motor of the sheet feeding mechanism, the sheet feeding device further comprising:correction value storage memory which stores a plurality of correction values for drive pulses applied to the feed motor in correspondence with various sheet feed amounts based on a number of drive pulses;selecting means for selecting a correction value which minimizes the sheet feed error of the sheet feeding mechanism from among the correction values stored in the correction value storage memory, based upon a visual observation of a printed pattern as a result of printing execution;wherein the drive-controller reads the correction value, which minimizes the sheet feed error of the sheet feeding mechanism, from among the correction values stored in the correction value storage memory, and corrects the sheet feed amount in the sheet feeding mechanism based on the selected correction value.
