choose to slow the scanner speed rather than replace all labels, or you may want to
slow the scanner speed while you wait for an opportunity to re-label the media.
Depending on the severity of the problem, the error recovery procedure (ERP) for
poor labels may greatly exceed the time lost by slowing the scanner. If you have
cartridge bar code labels that meet the LTO bar code label specification, there is no
need to slow the scanner speed. For information about slowing the scanner speed,
see the section about adjusting the scanner speed in the IBM System Storage TS3500
Tape Library with ALMS Operator Guide.
To order bar code labels, see “Ordering bar code labels for Ultrium cartridges” on
page 171.
Guidelines for using Ultrium bar code labels
Apply the following guidelines whenever you use Ultrium bar code labels:
v Use only IBM-approved 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 they are 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 you apply it to the cartridge. Do not use the label if it
has voids or smears in the printed characters or bar code (an application'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 bar code label area.
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 bar code reader to read the bar code.
