Abstract: A sheet laminator including a thermal pressure roller, a power cutoff device, a mover, a power line, and circuitry. The thermal pressure roller pair includes first and second rollers, and first and second heaters, to form a nip region to press and convey a two-ply sheet. The power cutoff device detects a change in temperature of at least one of the first or second roller, and cuts off a power to at least one of the first or second heater. The mover relatively moves the second roller away from the first roller. The power line couples the power cutoff device to the mover. The circuitry is to cause the power cutoff device to cut off the power line, and cause the mover to relatively move the second roller away from the first roller, in response to the power cutoff to at least one of the first or second heater.

Abstract: A stencil printer of the present invention perforates, or cuts, a thermosensitive stencil with a thermal head to thereby make a master. The stencil printer includes a stencil distinguishing device for automatically identifying the kind of the stencil or a master setting device for allowing the operator of the printer to set the kind of the stencil. An adjusting device selects, among master making conditions experimentally determined beforehand, a master making condition matching with information output from the stencil distinguishing device or the stencil setting device. The operator can easily change the master making condition in accordance with the kind of a stencil to use.

Abstract: An image forming system includes an image forming apparatus and a sheet laminator. The image forming apparatus forms an image on a sheet being conveyed as an inner sheet. The sheet laminator performs a sheet laminating operation on a two-ply sheet in which the sheet conveyed from the image forming apparatus is inserted between two sheets of the two-ply sheet. The sheet laminator includes a heater and circuitry. The heater heats the two-ply sheet during the sheet laminating operation. The circuitry is to execute a control mode when a specific abnormal event occurs among a plurality of abnormal events that occurs in the image forming apparatus, where the control mode maintains heating by the heater of the sheet laminator for a predetermined time and interrupt the heating by the heater when an abnormal event other than the specific abnormal event occurs.

Abstract: A sheet processing apparatus including a sheet feeder, a sheet processing device, a sheet ejection device, a purge unit, a multifeed sensor, a sheet sensor, and circuitry. The circuitry stops an operation of the sheet processing apparatus when the multifeed sensor has not detected multifeed of the sheet and the sheet sensor does not detect a trailing end of the sheet after a first set time from detection of a leading end of the sheet, stop the operation when the multifeed sensor has detected the multifeed and the sheet sensor does not detect the trailing end of the sheet after a second set time from the detection, and conveys the sheet toward the purge unit without stopping the operation when the multifeed sensor has detected the multifeed and the sheet sensor detects the trailing end of the sheet before the second set time elapses from the detection.

Abstract: A thermal master making device and a thermal printer including the same are disclosed. A thermistor senses ambient temperature around a thermal head. A correcting device corrects the amount of heat to be generated by the thermal head, i.e., the duration of energization at least two times during a single master making operation. This configuration reduces a change in the perforation conditions of a thermosensitive medium ascribable to the heat accumulation characteristic of the head. The printer achieves high resolution, high-speed master making and space saving.

Abstract: A master making device includes a thermal head with heat generating elements and a platen roller. While the head and platen roller convey a thermosensitive medium in a subscanning direction perpendicular to a main scanning direction, the heat generating elements selectively generate heat in order to perforate the medium in accordance with an image signal. The head includes a stepped portion formed at a medium outlet side in the subscanning direction. The edges of the heat generating elements adjoining the medium outside side are located at a distance of 0.018 mm to 0.5 mm from the end of the stepped portion adjoining the above edges. It is not necessary to position the head with respect to an effective nip between it and the platen roller by a troublesome procedure. Further, the distance over which the perforated medium is conveyed is reduced to obviate the reduction or contraction of an image ascribable to the sticking of the medium to the head.

Abstract: A sheet laminator includes a sheet ejection roller pair, a sheet ejection tray, a presser, and circuitry. The sheet ejection tray has a receiving face to receive the two-ply sheet standing in the sheet ejection tray, and a stacking face facing the receiving face and inclined with respect to the vertical direction. The presser has a leading end to move the two-ply sheet on the receiving face toward the stacking face, and press the two-ply sheet onto the stacking face. The circuitry is to perform a first operation to move the leading end of the presser from the receiving face to an intermediate position beyond the extension line and before the stacking face, perform a second operation to move the leading end of the presser from the intermediate position to the stacking face, and press the two-ply sheet against the stacking face with the leading end of the presser.
