  • Page 22: About The Ncr 7870 Scanner/Scale

    Bi-optical scanning creates a larger, four-sided scan zone which allows the 7870 to read bar codes faster and with less orientation effort from the checker. Scan line speeds of 2,400 lines per second permit continuous item speeds of 2 meters per second. A good checker operates in the range of 0.8 to 1.0 meters per second.

  • Page 24 This is the standard bi-optic scanner only model. It is full-sized, designed to fit in a 20+ inch (51+ cm) wide checkstand. It can be configured with a variety of top plates and glass options. The 7870- 1000 will fit into the counter hole for the NCR 7820.

  • Page 25: Chapter 2: Features, Functions, And Kits

    EAN-8/13 JAN-8/13 It is possible that in some situations, the 7870 may be able to read more types of bar codes than the host terminal’s application program. In such a case, either the application program must be upgraded to read these bar codes or the 7870 must be told, using the Programming Tags (BST0-2121-74), to ignore the particular bar code type.

  • Page 26: Bi-Optic Scanning

    Chapter 2: Features, Functions, and Kits Bi-Optic Scanning The NCR 7870 combines horizontal and vertical scan patterns. Having two active scan windows allows the checker to bring a product into the scan zone without having to orient it to a single scan window. Portions of the bar code are read by each scanner, assembled into a complete code by the digital board and sent to the host terminal.

  • Page 27: Displays

    In Mode 1 the tally counts are displayed on the integrated display or the NCR 7825 remote display. The percentage of each error type to the good reads tally is also displayed. All the tally counts can be reset to zero.

  • Page 28: Integrated Display

    Compact Display Depending on the checkstand construction, a keyboard may be mounted above the 7870, which will obstruct the view of the integrated display. In this case, it may be advantageous to install an NCR 7825 Post Mounted Display, which can be used with or without an integrated display.

  • Page 29: No Display

    This enables the 7870 to read at a continuous item speed of 2.0 meters per second. An experienced checker scans at a rate of 0.8 to 1.0 meters per second, so the 7870 is able to keep up with high volumes and fast checkers.

    7-68 Chapter 7: Programming Special Programming Some of the NCR 7870 features require programming that is somewhat different than the normal programming. Delay Weight Data to IBM Host Terminal A timing condition is possible when the NCR 7870 Scanner/Scale communicates with an IBM host terminal. The condition occurs when the IBM Host is requesting weight data, but the scale is not settled.

    Chapter 7: Programming 7-69 EAN/JAN/UPC Multi-Symbol Scanning Parameters The optional Multi-Symbol programming feature permits you to scan bar code labels containing two or three EAN-13, JAN-13, or UPC-A symbols. Label Construction A multi-symbol label must consist of any combination of two or three EAN-13, JAN-13, or UPC-A symbols, each with different flag digits.
  • Page 186 7-70 Chapter 7: Programming Perform the following to program the NCR 7870 for multi-symbol scanning. 1. Disconnect the communications cable from the scanner or the terminal. 2. Apply power to the NCR 7870. 3. To enter the Multi-Symbol program parameters mode, scan the following tags: Programming Mode, Hex 1, Hex 3, and Hex F.
  • Page 187 6. Scan the Save and Reset tag to save the multi-symbol programming. The scanner should go through a sequence similar to a power up sequence. 7. Remove power from the NCR 7870 and connect the communications cable. Chapter 7: Programming 7-71...
