Note: This scanner is standard on most Lx3 libraries. However, if you are
unsure or if the scanner is not reading the labels, contact your IBM Service
Representative. The service procedure for verifying the type of scanner is
documented in RPQ 8B3510.
v The guidelines for using Silo-style bar code labels with the TS3500 Tape Library
must be followed.
Proper placement of the bar code label is required for optimum bar code scanner
performance. Follow these placement guidelines for Silo-style bar code labels on
3592 tape cartridges:
v Ensure that the label is top justified and centered within the recessed label area.
The VOLSER label should not fall into the media type label area.
v Ensure that the label is applied to the cartridge with the bars facing down (text
on top and bars on the bottom).
v Ensure that the label is applied straight, as a crooked label may cause label
reading problems.
In addition to these specific guidelines, also adhere to the general label guidelines
that are listed in “Guidelines for using 3592 bar code labels” on page 185.
Note that the bar code scanner only reads the VOLSER. If a single character media
type identifier is applied, it is ignored by the library. Also, it is difficult to read the
label of a cartridge mounted in the drive. Slower operation and repeated read
attempts may be observed. This is normal for these labels.
