Scanner Operation Summary
This summary identifies the correct barcode scanning procedure. Refer to this summary if
there is a problem reading a barcode.
Scan the Bar Code Label
Pass-by Scanning
Slide the merchandise across the window of the scanner with the barcode facing the scanner
window. To minimize scratching, try not to contact the Scan Window.
Presentation Scanning
Move the merchandise toward the scanner so the bar code label moves toward the center of the
Scan window. To minimize scratching, try not to contact the Scan Window.
Hand Scanning
Carefully pick up the scanner and move it toward the merchandise so the center of the Scan
Window moves toward the bar code label. To minimize scratching, try not to contact the
merchandise or drop the scanner.
Observe the Read Indication
The scanner gives either a Good Read indication or no indication. A Good Read is indicated by
the Status Indicator light going from red to green and then back to red. If the Good Read tone
is enabled, the 7893 also beeps.
Good Read Indication
Put the merchandise on the counter top and go to the next item entry.
No Read Indication
Examine the bar code label. If it appears to be good, remove any folds or obstructions and try
to read it again. Be sure you position the label within the scan pattern and close to the scanner.
If the bar code still does not read, key in the merchandise information on the host terminal.
