6.
The bar code reader has failed.
7.
The barcode labels are dirty or damaged.
6.2.4 The Barcode Reader does not read bar code labels reliably.
The library uses the Code 3 of 9 (also know as code 39) barcode format for the car-
tridge labels. In the default configuration, a check character is expected. This can be
altered in the configuration. If the library is configured for a check character, and
none is present on the labels, then the library will be unable to read the labels. If the
library is configured for no check character, and there are check characters on the la-
bel, the library will interpret the check character as an additional character, and you
will see one extra character in the element label reported on the SCSI bus or in the
menus.
Possible causes:
1.
The barcode labels are not of a high enough quality for reliable reading.
2.
The barcode labels are dirty or damaged.
3.
The barcode labels are printed in a code that the library configuration does not
understand.
4.
The lens on the face of the barcode reader is not clean.
5.
The configuration is set to the wrong type of barcode reader.
6.
The barcode reader has failed.
7.
The Configuration\Advanced\Changer\LabelCheckChar (label check character)
option is not set correctly.
6.2.5 When the library takes an inventory and reads the barcode labels, it scans
the tapes without barcode labels repeatedly.
The library can be configured to make several attempts to read a label with the bar-
code reader, if it cannot read the label the first attempt. If the library is configured
this way, and no label is on the cartridge, it will be scanned several times before the
library abandons the effort.
Possible causes:
1.
The Fixed Labels value in the Configuration\Advanced\Changer\Inventory
menu is set to ALL, and some of the Fixed Slot cartridges do not have barcode
labels. Change the Fixed Labels value to SOME, or put bar code labels on all of
the Fixed Slot cartridges.
2.
The Mag. Labels value in the Configuration\Advanced\Changer\Inventory
menu is set to ALL, and some of the magazine cartridges do not have bar code
labels. Change the Mag. Labels value to SOME, or put barcode labels on all of
the magazine cartridges.
