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.
