Scanning Procedure
To use the NCR 7870, the item must pass through the active scan
region. Item orientation, motion, and sequential handling are required
for proper label reading.
Instructions
1. Verify scanner is operable. The red Status Indicator must be lit.
2. Locate label on item.
3. Orient item so label faces away from you.
4. Pass item across the lower scan window.
5. If a good read occurs, the green Status Indicator will flash. A tone
will sound if the Good Tone parameter has been enabled. The red
Status Indicator will light indicating the unit is ready to read
another bar code.
6. If a good read does not occur, scan the item again.
7. If a good read still does not occur, manually enter information for
the item. Continue to scan.
Not-On-File Error
The Not-On-File feature is available on the NCR 7870 only if the host
terminal has this capability. If a label is not in the price lookup file, a
special tone sounds three times a second and the red Status Indicator
flashes repeatedly. The volume of the Not-On-File tone is
programmable.
The unit becomes disabled from reading additional labels until the
error is cleared. To clear, press the host terminal’s CLEAR key and
manually enter the information.
