    Ventilation RequirementsThe RealScan 7875 is designed to operate without an exhaust fan in the checkstand;however, there must be adequate convection airflow. The ambient temperature insidethe checkstand cannot be higher than 40 C (104 F). Also, the ambient temperatureinside the checkstand cannot be higher than 7 C (12.6 F) above the ambienttemperature outside the checkstand. For example, if the ambient temperature outsidethe checkstand is 24.4 C (76 F), the ambient temperature inside the checkstand cannotbe greater than 31.4 C (88.6 F). If the checkstand contains other heat producingequipment, you may need to use forced air to keep the temperature within the specifiedrange. However, air coming into or leaving the checkstand MUST NOT enter or exitpast the RealScan 7875.

    RS-232 Peripheral CablesThe cable on some RS-232 hand-held peripheral devices is not long enough to connect tothe RealScan 7875 (under the checkstand) and still permit easy use of the device. Inthese cases, NCR recommends that you install an extension cable. You can obtain onefrom NCR (Corporate ID Number 1416-C313-0040) or you can make your own. If youmake your own, it should be approximately 39 inches (1 meter) long with 8-pin phonetype connectors on each end.

    Step 4 Calibrate the ScaleNote: The Bizerba computing scale, used in a RealScan 7875-4000, is calibrated at thefactory and cannot be calibrated in the field. However, you can reset the scale byturning off the power, then turning it back on with no weight on the Top Plate. If youare installing a RealScan 7875-4000 with a Bizerba scale do not attempt to calibrate thescale, but continue to Step 5 Check the Scanner Operation.

    Note: You MUST calibrate the scale when you install a RealScan 7875. To be incompliance with governmental weights and measures regulations, you must be certifiedto calibrate the scale.

    Note: Calibration information is NOT sent to the host terminal. If your RealScan 7875does not have voice enabled or does not have an integrated or remote display, you mustuse a Field Service Calibration Display.

    Note: Be sure the Interface Cable between the RealScan 7875 and the host terminal isdisconnected during scale calibration. Some host terminals can cause interference thatcan invalidate the scale calibration.

    You can calibrate the scale after power has been supplied for 30 minutes if the ambienttemperature has been 20 C (68 F) for at least 24 hours. If this condition is not met, thenthe scale must be on for at least 6 hours before you can calibrate it. Also, you must use acertified weight set to calibrate and certify the scale.

    The RealScan 7875 maintains an audit trail of scale calibration and programmingactivity. The audit trail records the number of times the scale has been calibrated. Youcan display the audit trail count on an Integrated, Remote 7825, or Field ServiceCalibration Display by pressing the Scale Zero Button on the Operator Display Panel.The display alternates between Cal xxx and PAr xxx.

    Exercise the ScaleYou must exercise the scale before performing a calibration. Add and remove weight toyour scale in the order given in the following chart. This is a building procedure inwhich you start with no weight (0) and sequentially add and remove weight to obtainthe values shown in the chart. Go through this procedure four times.

    Step 5 Check the ScannerOperation

    Now you need to make any necessary programming changes to the RealScan 7875 andthen scan some bar codes to assure the scanner is working properly. The RealScan 7875does not have an On/Off switch. Use the circuit breaker switch in the checkstand thatsupplies power to the unit as the On/Off switch.

    Setting the Program ParametersCaution: Some host terminals can corrupt the RealScan 7875 program if they arerunning and are connected to the RealScan 7875 while you are making programchanges. Either turn off the host terminal or disconnect the interface cable beforescanning any programming tags.

    To make changes to the program parameters, enter information from the ProgrammingWorksheets located toward the back of this book. The Programming Worksheetsidentify all the available program parameters. Each worksheet relates to a specificprogramming mode. Most programming options have defaults, identified by a heavybox, which are determined at the factory. Scanning the Default tag as the first tag afterapplying power to the unit sets the parameters to these values.

    Changing the RealScan 7875 program is accomplished by scanning the proper sequenceof programming tags. Following are three major steps for making program changes.

    1. Enter the Base Programming State by scanning the Programming Mode tag; mustbe first tag scanned after applying power.

    2. Select a Programming Worksheet and enter its parameter data by scanning theappropriate Hex tags.

    3. Save the program by scanning the Save and Reset tag.

    Note: In most cases the factory determined defaults are the correct parameter setting.However, if you do need to make changes, it is recommended that you first set allparameters to default values then make any necessary changes to the appropriateparameters.

    Operating the ScannerThe RealScan 7875 is a fixed position device that is installed in a checkout counter. It isnot handled or moved by the operator during operation. The RealScan 7875 ismaintained and serviced by trained service personnel only. The operator has no accessto any laser module components.

    The RealScan 7875 does not have a power switch. However, you turn it on and off byusing the circuit breaker switch, located in the checkstand, that supplies power to theunit. Be sure this switch is in the On position.

    The Status Indicator on the Operator Display Panel is Red when the RealScan 7875 isready. The correct way to scan is to slide an item from the checkstand, across thescanner, and back onto the checkstand. With a good scan, the Status Indicator FlashesGreen, then turns Red. Nothing happens if the bar code is not read.

    Operating the ScaleThe RealScan 7875 typically takes from 1.0 to 2.0 seconds to weigh an item, dependingon the items weight. The heavier the item, the longer it takes. Before weighing an item,make sure the scale display is displaying all zeros. If not, press the Scale Zero Button.

    Note: The item you are weighing should be placed in the center of the Top Plate. Makesure the item does not overhang onto the checkstand; whatever is weighed must fit fullyon the Top Plate. If the RealScan 7875 includes the Produce Guard, larger items may restagainst it.

    When the scale weighs an item, the Status Indicator flashes Green and a good weightone is sounded. Nothing happens if the scale cannot weigh an item.

    Cleaning the RealScan 7875Keeping the scan windows clean helps keep the read rate exceptionally high. Duringnormal operation the scan windows get dirty, and if you permit the dirt to accumulate,performance degrades to the point where the scanner cannot read bar codes. The PleaseClean Window indicator flashes when the scan windows need cleaning. Use a soft clothmoistened with a common, non-abrasive, liquid window cleaner to clean the scanwindows. Be sure to spray the cleaner onto the cloth, not directly onto the RealScan 7875

    Note: Scale problems can occur from debris collecting under the Top Plate. Be sure tokeep the plastic Subplate clean to prevent interference with the Top Plate whenweighing items.
