Test Name

Description

MAILSLOT IO

Makes a combination of moves with a PASS/FAIL result. It

 

moves an optical disk from the lowest-numbered full slot to

 

the mailslot with a random flip. It then moves the cartridge

 

back to its original slot with its original orientation. This test

 

displays FAIL if there are no disks in the jukebox or if all

 

storage slots are full. The drives and mailslot must be empty.

 

 

VERTICAL TEST

Moves the disk transport mechanism up and down the full

 

length of the rail. Returns PASS/FAIL. No disks are

 

required.

 

 

TRANSLATE TEST

Moves the disk transport mechanism from side to side. No

 

disks are required.

 

 

FLIP TEST

Makes a combination of moves with a PASS/FAIL 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

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 HOME

Calibrates the reference points for the side-to-side motion of

 

the disk transport mechanism. No disks are required.

 

 

VERTICAL

Moves the disk transport mechanism down to the lower stop,

ENCODER

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.

 

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.

 

 

EMPTY PICKER

Moves a disk from the disk transport mechanism to its home

 

storage slot location if that location is known, otherwise the

 

disk is placed into the first available empty storage slot.
