20150368063 | APPARATUS FOR PERFORMING BINDING PROCESSING ON SHEETS AND POST-PROCESSING APPARATUS PROVIDED WITH THE SAME - In performing press binding with a pair of pressurizing surfaces opposed to each other with sheets nipped therebetween, one of the pressurizing surfaces is configured to shift to positions relatively to the other pressurizing surface, and a shift section is provided in the pressurizing surface that shifts to positions. An apparatus for applying narrow pressure to a plurality of sheets with a pair of pressurizing surfaces to perform press binding is provided with first and second pressurizing surfaces opposed to each other with sheets nipped therebetween, and a pressurization driver that shifts a position of at least one of the first and second pressurizing surfaces from a waiting position separated to an actuation position for coming into press-contact. | 12-24-2015 |
20160016753 | IMAGE FORMING APPARATUS, METHOD OF CONTROLLING THE SAME, AND STORAGE MEDIUM - An image forming apparatus that is capable of preventing failure of binding of printed sheets. A PDL processor determines based on print data whether or not needleless binding has been set. If needleless binding has been set, the PDL processor acquires a sheet type of each page from the print data. The PDL processor determines whether the sheet type of the page is needleless binding executable. The PDL processor replaces a sheet type which is determined to be needleless binding unexecutable, with a sheet type which is needleless binding executable. A post-processing apparatus performs needleless binding on the bundle of printed sheets in which any needleless binding unexecutable sheet is replaced with a sheet of the needleless binding executable type. | 01-21-2016 |
20160185559 | SHEET PROCESSING DEVICE, METHOD FOR CONTROLLING SHEET PROCESSING DEVICE, PROGRAM, AND STORAGE MEDIUM - A sheet processing device includes a stapler that executes stapling processing, a sheet detection sensor that detects a sheet as a processing target, and an execution button that receives an instruction to execute the stapling processing from a user. The sheet processing device lights up the execution button when the sheet detection sensor detects the sheet, and causes the execution button to blink when the execution button is pressed or a predetermined time period has elapsed. | 06-30-2016 |
