DR100 - Resolve Barcode Scanner Malfunction
This DR provides customer resolution steps for T134 on page 333.
Problem: The barcode scanner is communicating properly, but it cannot read any barcodes. There are two

• The barcode scanner is damaged.
1 Open the library door to gain access to the robot. Look for any obstructions in front of the barcode
scanner (inside the picker assembly).
2 If no foreign material is found, close the access door and wait for the library to complete initialization.

labels, contact Service for assistance with replacement of the picker assembly.
