Page 29

If the scanner lamp remains on after a long period of inactivity, turn off the scanner, wait 30 seconds, and then turn the scanner back on.

NOTE: The scanner lamp does not turn off when paper is in the automatic document feeder input tray.

Scanner does not scan right away

Make sure the power switch on the right side of the scanner is turned on.

If the scanner has not been used for a while, the scanner lamp might need to go through a warm-up period before scanning can begin. If the scanner lamp needs to warm up, it takes a moment after starting the software or pressing a scanner button for scanning to begin.

You can enable Instant Lamp On mode in the HP Scanner Tools Utility.

Scanner scans only one side of a double-sided page

Verify the following:

•For single pass duplex scanning, scan pages through the ADF.

•Select the Duplex setting in the scanning or copy software.

Scanned image is fuzzy

When scanning with the automatic document feeder (ADF), follow these steps:

1.Verify that the document original is not fuzzy.

2.Check for any obstructions in the scanner paper path and make sure that the paper guides are positioned appropriately. Try another scan.

3.If the scanned image is still of poor quality, clean the ADF.

1.Verify that the document original is not fuzzy.

2.Check to see that the item is in full contact with the scanner glass.

3.If the scanned image is still of poor quality, clean the scanner glass.
