The scanner stops scanning

If the scanner stops scanning, complete the following steps in order. After each step, start a scan to see if the scanner is working. If not, proceed with the next step.

  1. A cable might be loose. Ensure that both the USB cable and power cable are securely connected.

  2. Unplug the power cable from the power source, wait 60 seconds, and then plug it back in.

  3. Restart the computer.

  4. Test the scanner hardware by following the steps below:

    1. Verify that the transparent materials adapter (TMA) cable on the scanner lid is connected to the center connector on the back of the scanner.

    2. Disconnect the USB and power cables from the back of the scanner. Leave the power cable plugged into the wall power outlet.
    3. Open the scanner cover so you can observe the actions of the scanner mechanism.
    4. Press and hold the Scan and Copy buttons on the front panel of the scanner. While still holding the buttons depressed, reconnect the power cord.

      The TMA should turn on for three seconds and then turn off. After the TMA turns off, the carriage in the scanner should move forward and backward, and the scanner lamp should turn on. The scanner lamp should flash six times while the carriage is still in motion.
      • If the scanner completes the sequence correctly, the scanner is working correctly. The problem is either communication or software related.
      • If the scanner does not complete the sequence correctly there is either a power problem or a problem with the scanner.
    5. To end the test, disconnect the power cable.
  5. A software conflict might exist on the computer. The HP Image Zone software might need to be reinstalled. To do this, run the Repair utility.

    1. Click Start , point to Settings , and then click Control Panel (in Windows XP, click Start , and click Control Panel ).

    2. Click Add/Remove Programs , and then select the HP Image Zone software.

    3. Click Add/Remove (or Change , depending on the version of Windows).

    4. Follow the instructions on the computer screen, and then click Repair .

Scanner installation or setup issues

This section contains solutions for installation and setup problems.

Checking your computer

  • Verify that the computer meets the minimum system requirements listed on the scanner box.

  • If there is not enough hard-disk space, remove unnecessary files or install the software on a different disk drive.

Using administrative privileges

If installing the scanner on a Microsoft Windows 2000 or XP system, you must be logged on as an Administrator. See the operating system help for how to log on as an Administrator.

Using a valid folder

On a Microsoft Windows computer, if an error message window such as Destination Directory Is Invalid or Program Folder Is Invalid opens during installation, read/write permissions to that folder are not set.

Transparent materials adapter (TMA) problems

Use this section to help resolve issues that might occur when scanning 35 mm slides and negatives from the transparent materials adapter (TMA).

The transparent materials adapter does not work at all

The adapter cable might not be connected correctly. Ensure that the adapter cable is connected securely to the TMA port on the back of the scanner.

No light or only dim light is visible in the transparent materials adapter

After each step, start a scan to see if the scanner is working. If not, proceed with the next step.

  • Verify that the transparent materials adapter (TMA) cable on the scanner lid is connected to the center connector on the back of the scanner.

  • The bulb in the adapter might not be working. Press the Scan Slides or Negatives button and look for illumination in the TMA. If the bulb is broken, service is required.

  • The adapter has a short warm-up mode. Wait a few seconds to see if the light turns on. For the best scanning quality, let the adapter light warm up for at least 30 seconds.

Problems scanning slides or negatives

The image cannot be enlarged

Zoom in was probably selected instead of Resize. Zoom in changes only the view on the screen. Use Resize to change the size of the scanned image. See the HP Image Zone onscreen help for more information.

Incorrect colors print, or the image is too light or dark

  • A final scan area might not have been selected. The software might be setting the exposure for the entire area instead of the final scan area. Select and drag the handles around the desired selection area for the final scan.

  • The settings for transparent materials are reversed. Select Slides from TMA for slides or Negatives from TMA for negatives.

  • Ensure that the adapter windows are not blocked or dirty.

The scanned image shows a colored tint, usually pink

The image was probably scanned without using the adapter.

Dots or streaks appear in the scanned image

  • Check the original slide or negative for damage or debris.

  • Clean the scanner glass.

  • Clean the adapter windows using a slightly damp, soft cloth.

The scanned images are dark

  • Check to see if the adapter light is on before clicking New Scan or Accept .

  • The bulb in the adapter might be broken or not working. If the bulb is broken, service is required.

The scanned image is black even though the adapter light is on

  • From the Basic menu in the HP Image Zone software, click Lighten/Darken .

  • Ensure that the adapter windows are not blocked or dirty.
