Guidelines for Using Bar Code Labels
Apply the following guidelines whenever using bar code labels:
v
Do not reuse a label or reapply a used label over an existing label.
v
Before you apply a new label, remove the old label by slowly pulling it at a
right angle to the cartridge case.
v
Use peel-clean labels that do not leave a residue after being removed. If there is
glue residue on the cartridge, remove it by gently rubbing it with your finger.
Do not use a sharp object, water, or a chemical to clean the label area.
v
Examine the label before applying it to the cartridge. Do not use the label if it
has voids or smears in the printed characters or bar code (a library's inventory
operation will take much longer if the bar code label is not readable).
v
Remove the label from the label sheet carefully. Do not stretch the label or cause
the edges to curl.
v
Position the label within the recessed label area (see 5 in Figure 6-1 on page
6-1).
v
With light finger pressure, smooth the label so that no wrinkles or bubbles exist
on its surface.
v
Verify that the label is smooth and parallel, and has no roll-up or roll-over. The
label must be flat to within 0.5 mm (0.02 in.) over the length of the label and
have no folds, missing pieces, or smudges.
v
Do not place other machine-readable labels on other surfaces of the cartridge.
They may interfere with the ability of the drive to load the cartridge.
Write-Protect Switch
The position of the write-protect switch on the tape cartridge (see 1 ) determines
whether you can write to the tape. If the switch is set to:
v
The locked position
(solid red), data cannot be written to the tape.
v
The unlocked position (black void), data can be written to the tape.
If possible, use your server's application software to write-protect your cartridges
(rather than manually setting the write-protect switch). This allows the server's
software to identify a cartridge that no longer contains current data and is eligible
