How to use

Install the Magellan 3550HSi at a fixed checkout or scanning station and connect it to the host system using the appropriate wired interface. Position items so the barcode passes through the scanner’s active scan zone; for smartphone-displayed codes or Digimarc watermarks, present the screen steadily within the scan area. Use the Micro-B USB service port or insert a Micro-SD card to perform firmware updates or load configuration files as required.

Recommendations

For best results, mount the scanner at recommended checkout height and maintain a clean scanning window. Allow the Object Sense illumination control to operate normally to balance user comfort and read performance. Use supported interface and configuration settings that match your POS or host system and apply firmware updates from Datalogic when available.
