Polaroid has found that the load sensor for the film carrier can sometimes
collect dust that renders the sensor inoperative. The scanner may run
continuously. Running continuously can also occur if the scanner is set to
SCSI ID 7 which is a test position and not a fault.
Polaroid has made available, free of charge, a cleaning brush kit that
cleans this sensor. For customers in the US, call 1-800-432-5355 (Mon-Fri,
8am to 8pm EST). Ask for a SprintScan 4000 Cleaning Brush Accessory, part
number CPS 546
