Test Name
Description
FIND PLUNGE HOME
Runs mechanism recalibration, establishes which
picker side is up, and determines the reference
points in the picker travel path. This test assumes
that the mechanics and servo system are functional.
No cartridges are required.
FIND VERT HOME
Recalibrates the vertical position and verifies
that the vertical path is clear. No cartridges are
required.
FIND XLATE HOME
Calibrates the translate position. No cartridges are
required
VERTICAL ENCODER
Moves the disk transport mechanism down, then
moves it back up a short distance, and then moves
it back down. The last time the disk transport
mechanism is moved down the number of encoder
counts are verified. Returns PASS/FAIL. No
cartridges are required.
CAUTION
Use extreme caution when running the next three
tests.
EMPTY DRIVES
Moves cartridges out of the drive mechanism(s)
and returns them to their storage slots, if locations
are known.
EMPTY PICKER
Moves an optical disk from the disk transport
mechanism to its home storage slotlocation if that
location is known, otherwise the disk is placed into
the first available empty storage slot.
FILL PICKER
Moves an optical disk into the disk transport
mechanism from the first storage slot containing a
disk. This test must be run twice to fill both slots in
the transport mechanism.
EXERCISE MECHANICS
Runs the VERTICAL TEST, TRANSLATE
TEST,
FLIP TEST, MAGAZINE IO, DRIVE IO, and
MAILSLOT IO tests. Each test is run one time per
test loop.
