Communication
This SelfCheck™ System sends and receives information from the
auto circulation system (ACS). This information is exchanged in a
manner consistent with 3M’s Standard Interface Protocol (SIP-2).
This SelfCheck system also communicates with patrons by
identifying the patron's ID and leading them through the process of
checking out materials. The SelfCheck™ System displays correction
instructions to help the patron solve problems. If this fails, the system
instructs the patron to ask for help at the circulation desk.
Bar Codes
Bad or Unreadable Bar Codes
When the scanner tries to read a bar code that is not configured on
the SelfCheck system, or if the bar code is unreadable (damaged or
incomplete), an error screen displays and the patron is instructed to
seek help at the front desk.
Bar Code Formats
The SelfCheck system identifies library cards and library materials by
reading bar codes on the items. Several bar code formats have been
developed. The SelfCheck system is pre-programmed to read the
following bar code formats:
§
Codabar
§
Code 39
§
Plessey
§
Telepin Alphanumeric
§
Code 128
§
EAN-13
§
UPC-A
In addition to the bar code formats listed above, the scanner can be
set to read one additional format.
Bar Code Placement
Consistent bar code placement on library materials is necessary for
the scanner to read the bar codes. If the bar code placement on
library materials varies, the SelfCheck system must be set up in the
center-scanning configuration.
