Summary:A printing carriage comprises a printhead, and two sensors for scanning an image deposited on a print media by the printhead. The sensors are provided on opposite sides of the printhead in a direction of movement of the printhead so that, during a printing pass of the printhead on the print media, one sensor is positioned on a trailing side of the moving printhead. Un chariot d'impression comprend une tête d'impression, et deux capteurs pour balayer une image déposée sur un support d'impression par la tête d'impression. Les capteurs sont disposés sur des côtés opposés de la tête d'impression dans une direction de déplacement de la tête d'impression de telle sorte que, pendant une passe d'impression de la tête d'impression sur le support d'impression, un capteur est positionné sur un côté arrière de la tête d'impression mobile.
