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.
