Abstract
An information process device according to an embodiment includes a thermal head that prints on paper at positions along a width direction based on a reference position. The sensor is at a sensor position in the width direction and detects marks on paper being conveyed by a conveyance unit. The controller controls the conveyance unit to convey a confirmation sheet and then detects a position of a mark on the confirmation sheet with the sensor. The detected position corresponds to the sensor position. The controller next controls the conveyance unit and the thermal head to print a line on a sheet corresponding to the sensor position. The controller is configured to receive a corrected sensor position based on a measured distance of the printed line to an edge of the sheet and update the print reference position accordingly.
