Step 5 Check the Scanner Operation
When power is applied to the RealScan 7872, it automatically performs a power on
wellness check on various components.
Scanner Units
After passing the power on wellness check, the Status indicator flashes green, a tone
sounds, then the Status indicator turns red. The RealScan 7872 is now operational.
Scanner/Scale Units
After the scanner passes the power on wellness check, the scale goes through a power
on wellness check. During this time all segments on the remote display are turned ON
so the operator can verify the display is working. Then the display reads 0.000kg or 0.00
lb. The Status indicator flashes red for five seconds, then it flashes green momentarily. A
tone then sounds and the Status indicator turns red. The RealScan 7872 is now
operational.
If The Unit Does Not Pass the Power On Wellness Check
If an error occurs during the power on wellness check, the remote display displays an
error code, and if available, the RealScan 7872 emits an audible description of the error
and what action to take. Refer to the
Correcting Scanner/Scale Problems
section for
additional assistance.
Verify Bar Code Reading
To verify the bar code reading operation of the RealScan 7872, attempt to read a good
tag on an item. The Status indicator should be red when ready to scan a bar code. A
good read is indicated when the Status indicator turns green and a tone sounds (if
enabled). Some good sample bar codes are provided to test the scanner.
Programming
The RealScan 7872 comes from the factory with the programming parameters set to
default values. The Communications Protocol is set at the factory to the specifications
you requested on the order. However, you may want to make some parameter changes
for the particular installation.
Any necessary programming changes to the RealScan 7872 must be performed now.
After programming changes have been completed, scan a number of bar codes to assure
the scanner is working properly. The RealScan 7872 does not have an On/Off switch.
Use the circuit breaker switch in the checkstand that supplies power to the unit as the
On/Off switch.
