HP Scanjet Enterprise 9000 Sheet-feed Scanner - Manual (Page 35)

• The document feeder or output tray might contain more than the maximum number
of pages. Load fewer pages in the document feeder, and remove pages from the
output tray.
• Clean the scanner paper path to help reduce misfeeds. If misfeeds still occur, clean
the rollers. If misfeeds still occur, replace the rollers.
Scanning fragile originals
To safely scan fragile originals (photographs or documents on wrinkled or very lightweight
paper) place originals in a clear, heavyweight document sleeve no wider than 300 mm
(11.8 in) before inserting into the document feeder.
Paper does not feed from the scanner
Re-load the pages into the document feeder, ensuring that they make contact with the
rollers.
The scanner hatch might not be securely latched. Open the scanner hatch and then close
it by pressing firmly.
A problem with the scanner hardware might exist. 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 green LED on the power supply
case 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.
3. Disconnect the power supply from the scanner and turn off the computer. After 60
seconds, reconnect the power supply to the scanner and then turn on the computer,
in that order.
4. Try to rescan.
Originals are curling up in the scanner output tray.
Under dry conditions, lightweight originals such as those printed on carbonless copy
paper may curl in the output tray. To minimize curl, flatten curled edges on the originals
before placing them in the document feeder. If you cannot flatten curled edges, make
sure the curled edges are facing down when you place the originals in the document
feeder.
The bottom of the scanned image is cut off
By default, the scanning software can scan media that is up to 432 mm (17 in) long. For
longer pages, the end of the document is not included in the scanned image.
Verify that you have specified an appropriate page size in the scanning software.
