HP StoreEver ESL G3 Tape Libraries - Manual (Page 156)

•
If there are a large number of issues, use rubbing alcohol to clean the picker fingers and the
detents in the side of the tapes.
•
If the problems persist, you might need to replace the picker assembly.
Scan fiducials
The scan fiducials graphical report shows the results for tests of the fiducial barcode on each tape
magazine and drive sled, including the width, expected Y position (shift), and the number of hits
the scanner receives while traveling up and down. (Only known magazines are tested.)
•
If the graphical report shows a failed result for one or more tape magazines, replace the
affected magazines.
•
If there are multiple marginal or failed results, run the library alignment test (part of the
installation verification or partial frame test) to ensure that the library is level.
•
If the library is level and there are multiple marginal or failed results, inspect the scanner and
replace it if necessary.
Picker pivot/reach
The picker pivot/reach graphical report shows the results for tests of the picker while performing
rotation and reach/retract actions.
See Figure 20 (page 157) .
