T082 - Barcode Scanner Failure
Description GUI Description: The library barcode scanner is not operating properly.
Explanation: The barcode scanner is detected to be in a state where the
library control logic cannot use it. Library robot power is known to be applied
(door is closed and robot is detected to be functioning enough to confirm that
power is applied), but scanner communication cannot be established at all or
appears to be not healthy.
Detection Scenarios • During any library bootup or door close operation, picker power is applied
and barcode scanner communication is established.
• During run-time operations such as inventory, where the barcode scanner is
used.
Root Causes • Scanner is physically disconnected.
• Various electrical hardware failures that prevent proper communication
between LCB and barcode scanner.
• Barcode scanner is not functioning properly.
Service Resolution
Steps
1 Perform RR004 - Remove and Replace Picker
Assembly on page 422. See
also Removing and Replacing the Robot Assembly
on page 164.
2 Clear the RAS ticket. Power down the library. Open the main door and
inspect the flex cable on top of the picker to determine if it is loose or not
seated properly.
Possible CRUs/FRUs Note: Read and perform all resolution steps before dispatching any parts.
Dispatch the first part listed below for replacement. If this does not solve the
problem, dispatch the second part, and so on, in order. Dispatch only one part
