A method and device for detecting, in a printer or scanner, the position of a carriage moving along a codestrip provided with a sequence of position marks. Sensors mounted on the carriage generate a detection signal each time that they detect an individual position mark, the timings of the detection signals are measured, and basic position information regarding the carriage is determined on the basis of these timings. Two sensors are arranged on the carriage at a predetermined distance, L, from one another in the direction of movement. The basic position information, derived from the timings of the detection signals from both sensors, is then calibrated on the basis of the distance, L, between the two sensors.
