From USPS News Link:
The Postal Service’s last Carrier Sequence Barcode Sorter (CSBCS), located in Opelika, AL, has been retired.
CSBCS deployment began in 1995, when the first of 3,750 machines — also known as “C’s” — was installed. Each machine processed 35,000 pieces of letter mail per hour.
Most C’s were placed in associate offices for sortation of letter mail. They helped sort the carrier’s mail into walk sequence each delivery day, with an initial carrier route primary sortation beginning the process.
The machines had a smaller footprint than the Delivery Barcode Sorters (DBCS) used at larger processing facilities. They required three passes to do the same amount of work as a DBCS.
Declining mail volumes led to the centralization of CSBCS machines in mail processing plants, and their utility diminished as sorting technology advanced. “Processing mail on a DBCS rather than on a CSBCS reduces operational and maintenance hours and increases efficiency,” said Delivery and Post Office Operations VP Ed Phelan.
Phelan said employees’ efforts to help make the removal a success were appreciated. “On behalf of the Postal Service, I’d like to thank everyone involved for their hard work in eliminating all the CSBCS machines in the field by the end of FY 2013.”
Retirement of the machines is expected to save USPS approximate $70 million each year.
