2 Power off the library.
3 Open the front door and remove the two magazines.
4 If the tape cartridge is toward you, grasp it and remove it gently. However, if the tape cartridge is away
from you, gently push it into a rear slot with a long narrow object like a ruler.
Barcode Labels
Cartridges to be scanned must have an external label that is machine readable to identify the volume serial
number. A barcode must use only uppercase letters A to Z and/or numeric values 0 to 9. The Scalar 24
currently supports Code 39 type barcode labels.
Three different types of barcode label modes are supported in the Scalar 24:
The barcode scanner will read and report the information that it scans and will display this information on
the operator panel. The library will report the barcode information to the host according to the mode it is
configured for and will display alert messages on the operator panel LCD if the scanned barcode does not
match the barcode length and media identifier requirements of the mode.
For customers who wish to print the barcode labels, the individual media labels are supported if the labels
meet the ANSI MH10.8M-1983 standard and other additional requirements. The requirements are:
• ANSI MH10.8M–1983 Standard
• Number of digits: 5–16 (based on mode)
• Background reflection: at least 25%
• Print contrast: at least 75%
• Ratio: at least 2:2
• Module: 250 mm
• Print tolerance: ± 57 mm
Additional Requirements:
• Length of the rest zones: 5.25 mm ± 0.25 mm.
• No black marks can be present in the intermediate spaces or rest zones.
• No white areas may be present on the bars.
• Bars should read in a uniform direction. Nonuniform reading directions have a detrimental effect on
performance.
Note
If a cartridge is partially in the drive and partially in the picker, contact ATAC for
removal instructions.
Default: The scanner will expect to read and report to the host six characters. If optional
one or two character media identifiers are present they will not be reported.
Media ID: The scanner will expect to read and will report seven or eight characters (six
plus the media identifier) to the host.
Extended: The scanner will read and report between 5 and 16 characters to the host.
Note
ADIC brand barcode labels are recommended.
