DR082 - Resolve Library Calibration Failure

This DR provides customer resolution steps for:
• T019 on page 216
• T020 on page 217
Problem: The library encountered a problem during calibration. This ticket can be caused by a blocked or
obscured line of sight of the calibration sensor, or a damaged white calibration target. This ticket may also
be caused by a brightly colored tape cartridge located in a slot immediately above a white I/E station
calibration target.
1 Note the ticket details to determine the library module, as well as any I/E or storage column, or drive
location; then close the ticket.
2 If the ticket details identified a module's I/E station column, perform the following steps:
a. Ensure that the I/E station in the identified module was firmly closed, to allow proper calibration.
b. If it was properly closed, open the I/E station and inspect the white I/E station calibration
target(s) for any damage, such as scratches in the white calibration target square.
c. If no damage is found, inspect the slot above the I/E station calibration target(s) for a brightly
colored tape cartridge (such as yellow or orange), and if such brightly colored tape cartridge is
present, ignore this ticket and continue.
3 If the ticket details identified a storage location, perform the following steps:
a. Open the module's access door identified in the ticket details; locate all white calibration targets
of the identified storage column, and inspect them for any damage.
b. If no damage is found, open the bottom module's main access door; gently move the picker
assembly toward the door opening, and rotate it gently as far clockwise as possible.
c. Open and fully extend the bottom I/E station door, then reach through the main access door
and locate the picker assembly's recessed calibration sensor in the picker base, just slightly to
the right of the picker's center line. Gently wipe the surface of the calibration sensor, using a
soft, lint-free cloth.
Note to Service: The picture below shows the location of the calibration sensor. If you are
guiding a customer by phone, you may want to copy the picture and e-mail it to them.
4 If the ticket details identify a drive sled, remove the identified drive and inspect the drive's calibration
bracket's horizontal white stripe for any damage.
