Scan failure,unable to read the configuration

usually you need to configure the reader to tell it what kind of barcodes you want it to read and how to interpret & output the codes to your computer (whether you need prefix or suffixes to your codes( for automation))

the user manual for the reader has some bar codes to configure the settings for the scanner.

Possible Reason:
1. High voltage power supply PCB
failure
---Replace the high voltage power supply
PCB ASSY.
2. Harness connection failure of high
voltage power supply PCB
---Check the harness connection of the high
voltage power supply PCB and reconnect
it.
3. Main PCB failure
---Replace the main PCB ASSY.

You should first run the Scanner configuration for PaperPort.

On the printer operator panel, press Black to begin a black and white scan or Color to begin a color scan. You can rename the file only on your computer once the scanned file is displayed.

what kind of scanner is it? is it a 2d barcode that you are trying to scan?

Also make sure it isn't a printer issue: ie: barcode is too light.

Does the scanner act like it sees the barcode? beep or any other notification?

Try using the HP Scan Diagnostic Utility in Windows - HP Customer Care (United States - English)

Open the given below link and perform all the steps in that:

You need to have someone with a full scan tool check it out. a code reader does just that...read codes. A full scanner will tell the mechanic much much more about what is going on with the engine.

I'm using the same Barcode reader, the Metrologic MS9535 VoyagerBT.

The brief humming noize is called a "Rasbery tone" in the manual. It means that the barcode reader is not configured to read that kind of barcode, a barcode Code if you will.

There are many types of barcodes so you have to go to the Metrologic Website and get the Barcode Configuration tool to configure your barcode reader to read the type of codes you will be using.

Alternatively there is a book with configuration barcodes you can scan to configure your barcode reader manually.

I have the same problem.
