Description
Details and Solution
2070 Inventory scan failed because
of Elevator axis problem.
• Check for obstructions in the vertical pathway of the
accessor such as a cartridge that is sticking out.
• Verify module alignment and frame alignment.
• For proper operation, the accessor must be able to reach the
bottom of the library. Verify that no obstructions are at the
bottom of the library or on the bottom cover of the library in
the path of the accessor.
1. To check for obstructions at the bottom of the library, rst
power off the library by pressing Power for 5 seconds and
select the Default Park location.
2. When the library is powered off, remove the left magazine
of the lowest library module, and verify that the entire area
of the bottom cover is free of any objects that might
obstruct the accessor's path.
3. After obstructions are cleared, replace the magazine, power
the library on, and after the library nishes initialization and
inventory, verify that no further critical events were
generated.
2071 Cartridge on picker when
trying to scan.
• Verify that no obstruction is in front of the bar code scanning
module on the cartridge table that is on the accessor.
• If the error persists, replace the accessor.

2076 I2C bus signals invalid.
• Remove all drive canisters of the affected chassis and restart
the library.
• If the problem persists, replace the chassis. If not, add one
drive after the other until the problem comes back.
• Replace the last drive that was added before it failed again.
2077 Failed to store Calibration
Data to Chassis.
Restart or power cycle system.
Note: This is a singular ticket and must be resolved manually.

reader rmware.
Restart the library and if the error persists, replace the
