摘要： A sheet laminator includes a fuser pressure member, a conveyor, and a guide. The fuser pressure member thermally fixes a two-ply sheet and a sheet medium inserted between two sheets of the two-ply sheet. The conveyor conveys the two-ply sheet toward the fuser pressure member in a sheet conveyance direction. The guide guides the two-ply sheet in a sheet conveyance passage between the conveyor and the fuser pressure member. At least one of the fuser pressure member or the conveyor is operable to guide the two-ply sheet outside the sheet conveyance passage in response to an occurrence of an abnormal stop of the sheet laminator.

摘要： A laminating system sandwiches a sheet medium in a two-ply sheet in which two sheets are overlapped and partially joined together and applies heat and pressure to bond the two-ply sheet. The laminating system includes a sheet separating device, a laminate-fixing device, and a conveyor. The sheet separating device separates the two sheets of the two-ply sheet and sandwiches the sheet medium between the two sheets. The laminate-fixing device heats and presses the two-ply sheet sandwiching the sheet medium. The conveyor conveys the two-ply sheet sandwiching the sheet medium from the sheet separating device to the laminate-fixing device. The laminate-fixing device is disposed above the sheet separating device.

摘要： A lamination processing system includes a sheet separation device, a lamination fixing device, and a conveyor. The sheet separation device separates a two-ply sheet to insert a sheet medium between two sheets of the two-ply sheet to form an enclosed two-ply sheet. The lamination fixing device includes an inlet port and a heater. The conveyor conveys the enclosed two-ply sheet from the sheet separation device to the lamination fixing device in a conveyance direction. The conveyor includes a conveyance passage and a guide. The conveyance passage guides the enclosed two-ply sheet from the sheet separation device toward the lamination fixing device. The guide guides the enclosed two-ply sheet to the inlet port. The guide forms a space accommodatable a deflected part of the enclosed two-ply sheet formed by a difference in a conveyance speed of the enclosed two-ply sheet between the sheet separation device and the lamination fixing device.

摘要： A sheet laminator includes a thermal fixing roller pair, a first heater, a second heater, multiple temperature detectors, and a driver. The thermal fixing roller pair includes a first thermal fixing roller and a second thermal fixing roller facing the first thermal fixing roller. The thermal fixing roller pair thermally fixes and conveys a two-ply sheet and a sheet medium nipped between two sheets of the two-ply sheet. The first heater heats the first thermal fixing roller. The second heater heats the second thermal fixing roller. The multiple temperature detectors are at different positions along an axial direction of the thermal fixing roller pair. The multiple temperature detectors detect a surface temperature of the thermal fixing roller pair. The driver drives the thermal fixing roller pair.

摘要： An image forming apparatus includes a transfer unit that transfers a toner image on an image bearer onto a transfer medium. The image forming apparatus includes a control unit that controls a transfer voltage to be output to the transfer unit in accordance with a certain condition. The control unit applies currents having at least two different values while paper is not being fed. The two current values are lower than a current value during paper feeding. The control unit estimates an output voltage on a basis of a voltage detected through the application of the currents. When the estimated output voltage falls below a certain limiter voltage, the control unit controls to bring the output voltage to a value calculated through the certain condition. When the estimated output voltage exceeds the certain limiter voltage, the control unit controls to bring the output voltage to the limiter voltage.

摘要： A sheet processing system includes a sheet processing device and a lamination processing device. The sheet processing device includes a sheet separator that separates a two-ply sheet and inserts an inner sheet between the two-ply sheet to form a first enclosed two-ply sheet. The lamination processing device bonds the first enclosed two-ply sheet, and bonds a second enclosed two-ply sheet in which the inner sheet is inserted outside the sheet separator. The sheet processing system includes a relay conveyor that conveys the first enclosed two-ply sheet from the sheet separator to the lamination processing device attachable to a sheet feeder to directly feed the second enclosed two-ply sheet to the lamination processing device. The sheet processing device includes a cord holder to hold the power cord of the lamination processing device at a position where feeding and ejecting the two-ply sheet after bonding the two-ply sheet are not hindered.
