Basic troubleshooting tips Simple issues such as smudges on the scanning strips or loose cables can cause your scanner to produce fuzzy scans, operate in an unexpected manner, or fail to operate. Always check the following items when you encounter scanning problems. ● If scans are fuzzy, check to see if the scanning strips inside the document feeder are dirty or smudged. If so, clean the scanning strips. If you are 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. TIP: You can change the auto-off setting on the Settings tab of the HP Scanner Tools Utility. ● Ensure that the scanner is receiving power. ◦ Check that the green LED on the power supply case is on. ◦ If the green 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 green LED is still not on, the power supply might be defective. Contact www.hp.com/support for assistance. ● If you receive a Scanner not found error message when trying to use the scanner, turn off the scanner, wait 30 seconds, and then turn on the scanner. If you still receive this message, you might need to reset the scanner. ● If you have connected the scanner 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. ● Make sure that the scanner buttons are enabled. ● 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 If you continue to have problems, it is possible that your HP scanning software, firmware, or associated drivers are out of date or have become corrupted. See www.hp.com/support to locate software, firmware, and driver updates for your scanner. ENWW Basic troubleshooting tips 43
