Basic troubleshooting tips

Simple issues such as smudges on the scanning strips or loose cables can cause the scanner to produce fuzzy

scans, operate in an unexpected manner, or fail to operate. Always check the following items when

encountering scanning problems.

If scanning a document that will be analyzed using optical character recognition (OCR), make sure that

the original document is clear enough to be analyzed.

Make sure that the USB and power cables are firmly seated in their respective connectors on the back of

the scanner, and that the power cord is plugged into a working electrical outlet or surge protector.

Make sure the scanner has not automatically powered off. If it has, press the Power button to turn on

the scanner.

Ensure that the scanner is receiving power.

Check that the Power LED on the control panel is on.

If the Power LED is not on, ensure that power is available to the power outlet or surge protector

that the power supply is plugged into.

If power is available to the power outlet or surge protector but the Power LED is still not on, the

power supply might be defective. Go to

www.hp.com/go/sj2000s1

or

www.hp.com/go/sj3000s3

for assistance.

If the scanning software displays a Scanner not found message when trying to use the scanner, turn off

the scanner, wait 30 seconds, and then turn on the scanner. If the message still displays, the scanner

might need to be reset.

If the scanner is connected to the computer through a USB hub or through a USB port on the front of the

computer, disconnect the scanner and then reconnect it to a USB port on the back of the computer.

Windows: Make sure that the Scan button is enabled (see “Product accessibility” for more

information).

Turn off the scanner, wait 30 seconds, and then turn on the scanner.

Make sure the document feeder hatch is closed.

Restart the computer.

If problems continue, it is possible that the HP scanning software, firmware, or associated drivers are out of

date or have become corrupted. See

www.hp.com/go/sj2000s1

or

www.hp.com/go/sj3000s3

to locate

software, firmware, and driver updates for the scanner.

Test the scanner

Follow this procedure to test the scanner:

1.

Ensure that the power supply is securely connected between the scanner and a live electrical outlet or

surge protector. Check that the Power LED on the control panel is on to verify that the power supply is

functional.

2.

If the power supply is connected to a surge protector, ensure that the surge protector is plugged into an

outlet and turned on.
