Frequently Asked Questions - Scanjet N8420 HP

How do I clear a paper jam in the ADF?

First, remove any loose pages from the input tray. Then open the ADF hatch and lift the green lever to raise the feed roller. Gently remove the jammed page. Lower the lever and close the hatch. If the jam is at the end of the paper path, gently pull the page out in the opposite direction. For internal jams, open the scanner lid, remove the ADF access door, and extract the paper. Refer to the Clear jams from the ADF section in the manual for detailed steps.

How do I clean the scanner glass?

Disconnect the USB and power cables. Open the scanner lid. Spray a mild glass cleaner onto a soft, lint-free cloth (do not spray directly on glass). Wipe the glass gently, then dry with a clean cloth. Avoid cleaners with abrasives, acetone, benzene, carbon tetrachloride, or isopropyl alcohol. Reconnect cables after cleaning.

How do I replace the feed roller and separation pad?

Turn off the scanner and disconnect cables. Open the ADF hatch. Lift the green lever to raise the feed roller. Remove the old feed roller and separation pad according to the replacement kit instructions. Install the new parts, lower the lever, close the hatch, and reconnect cables. Use the HP Scanner Tools Utility to record the replacement on the Maintenance tab.

How do I scan both sides of a double-sided page?

Enable the Duplex setting in your scanning software (e.g., HP Smart Document Scan Software profile). Load the originals into the ADF with the first page facing up and top into feeder. The scanner will automatically process both sides.

How do I set up a scan profile?

Open HP Smart Document Scan Software. Click New to create a profile, or select an existing one and click Edit. Configure settings on the Scan, Process, and Destination tabs. For example, you can set resolution, file format (PDF, TIFF), and destination (folder, email). Profile names up to 16 characters appear on the scanner front panel.

How do I assign a profile to a quick start button?

Open the HP Scanner Tools Utility. Click the Buttons tab. For a quick start button (1-4), select HP Smart Document Scan Software as the program, then choose the desired profile from the drop-down list. Click OK to save.

My scanner is not found by the computer. What should I do?

Close any scanning software. Disconnect the USB cable and turn off the scanner. Restart your computer. Turn on the scanner and reconnect the USB cable after the computer boots. Wait 30 seconds for the display to show Ready. If it fails, uninstall and reinstall the scanner software using the HP Scanning Software CD.

How do I enable long page scanning?

Create or edit a profile in HP Smart Document Scan Software. On the Scan tab, set the page size to Custom and enter dimensions up to 215.9 x 863.6 mm (8.5 x 34 inches). Alternatively, select Maximum to scan the full length. Note that long pages can only be scanned one at a time through the ADF.

How do I clean the ADF window?

Open the scanner lid. Locate the ADF access door on the underside of the ADF. Press the tabs and pull the door off. Use an HP paper-path cleaning cloth to clean the clear scan window inside the ADF and the white strip on the door. Also clean the clear scanning strip on the scanner bed. Replace the door until it clicks shut.

How can I filter out a specific color during scanning?

Open HP Smart Document Scan Software and edit a profile. On the Scan tab, click Advanced Settings. Go to the Color Dropout tab and select the color channel (red, green, or blue) you want to remove. This reduces file size and improves OCR accuracy for forms with colored lines.

Scanner operation problems

- Scanner will not turn on

- Scanner lamp stays on

- Scanner does not scan right away

- Scanner scans only one side of a double-sided page

• Scanned image is fuzzy

• Scanned pages are out of order at the scan destination

- Scanner is scanning items very slowly

• The image is completely black or completely white

• Scanned images are not straight

• Vertical white stripes appear on the printed page

- Scanner glass is dirty

- Scan files are too large

Scanner will not turn on

If the scanner will not turn on when you press the front panel scanner buttons, verify the following:

- The scanner power switch might be turned off. Be sure the power switch located on the back of the scanner is turned ON.

- The scanner may have been unplugged. Check to see that the power cable has not become disconnected from the scanner or unplugged from the power source.

- Check to see that the automatic document feeder (ADF) cable has not become disconnected from the scanner.

- The buttons might be disabled in the HP scanning software. Verify the Disable front panel buttons setting in the HP Scanner Tools Utility.

Scanner lamp stays on

The scanner lamp should time out and turn off automatically after a period of inactivity (about 15 minutes). This is the Power Save mode.

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.

Scanner does not scan right away

Make sure the power switch on the back of the scanner is turned ON.

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

Scanner scans only one side of a double-sided page

Select the Duplex setting in the scanning or copy software.

Scanned image is fuzzy

It is important that the item you scan comes in close contact with the scanner glass. If the resulting scanned image is not clear, check to see that the item is in full contact with the scanner glass.

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

Clean the scanner glass as described in the Care and maintenance section.

Scanned pages are out of order at the scan destination

Insert a multiple page document with the printed first page of the document facing up and with the top of the document into the feeder.

Scanner is scanning items very slowly

• If you are scanning to edit text, the optical character recognition (OCR) software program causes the scanner to scan more slowly, which is normal. Wait for the item to scan.
• The resolution might be set too high. Reset the resolution to a lower level. The scanner software automatically selects the resolution to provide the best balance between image quality and file size.

The image is completely black or completely white

The item might not be placed correctly on the scanner glass. Make sure that the item you are trying to scan is placed face down on the glass and the lid is closed. If scanning from the ADF, check the paper orientation.

Scanned images are not straight

The item might have shifted when you closed the lid. Straighten the original on the scanner glass, and then scan again.

Verify that the document feeder guides are centered on the scanner and set to an appropriate width for the original being scanned. Make sure the paper guides touch the edges of the original.

Vertical white stripes appear on the printed page

The destination printer might be out of toner or ink. Scan a different original to the same printer to see if the issue lies with the printer.

If the second original has the same problem, clean the scanner glass as described in Care and maintenance.

Scanner glass is dirty

Clean the scanner glass under the following conditions:

• Ink is on the glass • Fingerprints are on the glass
• Documents or other items placed on the glass have an excessive amount of dust or dirt on them
• Smudges or other marks appear on scanned images

• Haze or dust is on the glass

Allow the glass to dry thoroughly before scanning another image.

For more details, see Care and maintenance.

Scan files are too large

If the saved scans have very large file sizes, try the following:

• Verify the scan resolution setting:
• 200 dpi is sufficient for storing documents as images.
• For most fonts, 300 dpi is sufficient for using optical character recognition (OCR) to create editable text.
• For Asian fonts and small fonts, 400 dpi is the recommended resolution. Scanning at a higher resolution than necessary creates a larger file with no additional benefit.

• Color scans create larger files than do black and white scans.

- If you are scanning a large number of pages at one time, consider scanning fewer pages at a time to create more, smaller files.

- Use the Kofax VirtualReScan software to reduce the number of random gray or black dots that appear on a scanned image. Eliminating these dots can create a smaller file.

Scanner buttons are not working correctly

• Buttons do not work • An unexpected program opens when a button is pressed
• Wrong profile is used when a quick start button is pressed

Buttons do not work

After each step, press a button to see if it is working correctly. If the problem persists, proceed with the next step.

1. The buttons might be disabled in the HP scanning software. Verify the Disable front panel buttons setting in the HP Scanner Tools Utility.
2. A cable might be loose. Ensure that the USB cable and the power supply are securely connected.
3. Turn off the scanner, wait 30 seconds, and then turn the scanner back on.
4. Restart your computer.
5. If the problem persists, the buttons might be disabled outside of the HP scanning software. Try the following procedure:

a. Open Control Panel, select Scanners and Cameras, and then select your scanner model from the list. b. Examine the buttons setting for your scanner:

• Windows 2000: Ensure that the Disable Device Events option is not selected.

An unexpected program opens when a button is pressed

Depending on the HP scanning software installed on the computer, an unexpected program might open when a profile is selected and a button is pressed.

After each step, press a button to see if it is working correctly. If the problem persists, proceed with the next step.

1. Verify that the expected program is installed on the computer by looking at the Start menu.

If the program is not installed, then use the program CD to install the program.

1. If the problem persists, the buttons might be assigned outside of the HP scanning software. Try the following procedure:

a. Open Control Panel, select Scanners and Cameras, and then select your scanner model from the list. b. Ensure that the Start this program option is selected and that the correct application is selected in the drop-down list.

Wrong profile is used when a quick start button is pressed

6 Advanced technical features

Experienced document management professionals might be interested in the following scan features. These features are available from any document TWAIN or ISIS application that allows you to modify the scan settings in its user interface.

• Long pages
• Color dropout
• Misfeed (Multipick) Detection

Long pages

By default, the automatic document feeder (ADF) accepts a stack of originals up to 215.9 mm x 355.6 mm (8.5 inches x 14 inches). You can choose to scan single pages up to 215.9 mm x 863.6 mm (8.5 inches x 34 inches) through the ADF.

NOTE: If the scanner is set to scan long pages and a page jams, up to 864 mm (34 inches) of document pages can be wrinkled as a result of the jam. Therefore, select scan profiles that specify long pages only when you are scanning pages longer than 355.6 mm (14 inches).

To enable long-page scans in an HP Smart Document Scan Software profile, follow these steps:

1. Open the HP Smart Document Scan Software.
2. Select a scan profile, and then click Edit.
3. Set the page size:

On the Scan tab of the Profile Settings dialog box, select Custom in the Size drop-down list, and then type the actual page dimensions, up to 215.9 mm x 863.6 mm (8.5 inches x 34 inches), in the Width and Height boxes.

TIP: Alternatively, you can select Maximum in the Size drop-down list. The resulting scanned image size will be 215.9 mm (8.5 inches) wide and the actual page length up to 863.6 mm (34 inches) long.

NOTE: Some scanning and destination applications might not support long pages.

Color dropout

You can filter out specific colors from a document scan, for example, you can remove colored lines on a form. Removing colors from the scan reduces the scan file size and can improve the accuracy of optical character recognition (OCR). You can select to filter out one color channel (red, green, or blue).

To eliminate a color from a scan in an HP Smart Document Scan Software profile, follow these steps:

1. Open the HP Smart Document Scan Software.
2. Select a scan profile, and then click Edit.
