Error U002 Fujitsu fi-7700S: Paper Feed Issue

The Fujitsu fi-7700S error U002 is a common diagnostic signal indicating a failure in the document transport system. This error frequently triggers when paper is improperly fed or when the rollers lack the necessary friction due to dust or wear. Performing regular maintenance on the pickup and separation rollers usually prevents this error code from appearing during high-volume scans.
