 result. Flips the disk transport 

mechanism at various locations. No disks are 
required. 

PICKER TEST

Flips the disk transport mechanism and 
switches active thumbs. No disks are required.

FIND PLUNGE 
HOME

Calibrates the disk transport mechanism, 
establishes the 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 
HOME

Calibrates the reference points for the 
side-to-side motion of the disk transport 
mechanism. No disks are required.

VERTICAL 
ENCODER

Moves the disk transport mechanism down to 
the lower 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

EMPTY DRIVES

Do not run this test if the jukebox contains disks 
with customer data.

 Moves disks out of the drive 

mechanism(s) and 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.
