In daily use

Installed in the internal paper feed path before the imaging unit, the sensor continuously monitors sheet arrival and alignment. When paper reaches the registration point, the sensor triggers the timing sequence for image transfer, ensuring every page is positioned accurately. A failing sensor typically manifests as intermittent jams, skewed output, or registration errors—replacing it with this unit restores smooth, dependable operation in busy office environments.
