  • Electrophotographic device provided with a mechanism for attaching marks to edges of sheets
    Patent number: 5243394
    Abstract: An electrophotographic device records linear marks, according to jobs, at an edge of at least one side of a sheet. By designating according to jobs, the sorting of recorded sheets which are stacked up in a stacker is facilitated. The sheets are fed one after another by a carrier device, and thereafter an edge of the sheet is detected by a paper tip detecting device or a paper side edge detecting device. Based on the detected position of the paper edge, a linear mark K, corresponding to a position designated by a control device, is recorded on the sheet.
