Test Name
FIND PLUNGE Calibrates the disk transport mechanism, establishes the
HOME mechanism's orientation, and determines the reference
points in the picker travel path. Assumes that the
mechanics and servo system are functional. No disks
are required.
FIND VERT HOME Recalibrates the vertical position of the disk transport
mechanism and verifies that the vertical path is clear.
No disks are required
FIND XLATE Calibrates the reference points for the side-to-side
HOME motion of the disk transport mechanism. No disks are
required
VERTICAL Moves the disk transport mechanism down to the lower
ENCODER stop, moves it back up a short distance, and then moves
it back down. On the second downward motion the
number of digital pulses is counted and verified.
Returns PASS/FAIL. No disks are required
EMPTY DRIVES Used by service personnel only. Do not run this test if
the jukebox contains disks with file system data on
them
returns them to their home storage slot locations if the
locations are known. If the home storage location is not
known, the jukebox moves the disks into the first
available empty storage slot
EMPTY PICKER Used by service personnel only. Do not run this test if
the jukebox contains disks with file system data on
them
to its home storage slot location if that location is
known, otherwise the disk is placed into the first
available empty storage slot

the jukebox contains disks with file system data on
them
from the first storage slot containing a disk. This test
