1200 A3 Pro FAQ (Frequently Asked Questions)

1. The SCSI card and scanner are not showing up in the Device Manager, or the SCSI card is showing up with a yellow exclamation marks on it. During attempts to test or scan, the computer returns the message "Scanner link failure" or "Scanner not ready" and advises you to check your cables and connections.

2. The computer keeps finding new hardware every time Windows 95/98 is started and the scanner appears in the Device Manager with a yellow exclamation mark in front of it.

3. The scanner is locking up after clicking on "acquire," during prescans or is returning the error message "TWAIN error: error opening data source due to unknown causes."

1. The SCSI card and scanner are not showing up in the Device Manager, or the SCSI card is showing up with a yellow exclamation marks on it. During attempts to test or scan, the computer returns the message "Scanner link failure" or "Scanner not ready" and advises you to check your cables and connections.

Cause 1: The connections for the scanner may not be tight, or the interface card may not be seated completely at the bottom of the ISA slot. The scanner may not have been connected and powered on before booting the computer.

Cause 2: The SCSI card may have a conflict with another device.

Solution 1: When inserting the interface card, make sure that you use even pressure on both sides of the card. Do not rock it back and forth to insert it. If the card is fully seated, the gold connectors will appear to be even across the entire length of the top of the slot. Only the very top of the connectors should be visible.

The scanner should be connected to the card with the cable supplied. The cable that came with your scanner is an IEEE 1284 compliant SCSI cable, and is designed to keep signal strength and image quality high. Other kinds of cables and cable extensions may not provide adequate signal strength. It is strongly recommended to use only the original cable.

The scanner should also be turned on before booting the computer. When the power switch is turned on, the scanner will run through a short diagnostic and the front-panel green LED will flash rapidly. When it finishes flashing, the scanner is ready and the system can be started.

Windows should find the SCSI card and install the drivers for it automatically. After booting, the SCSI controller and scanner should appear in the Device Manager under SCSI Controllers and Other Devices. Follow these steps to see the Device Manager:

1. Click on the Start button and choose Settings.
2. From the Settings flyout window choose Control Panel.
3. In the Control Panel window open the icon labeled System.
4. Locate the tab for Device Manager and click on it.

To verify the status of the card, click on the plus sign (+), next to SCSI Controllers. A listing for an Adaptec AVA-1502 SCSI Host Adapter should be displayed. If the card and scanner are not displayed in the Device Manager, then recheck the connections. If the card is displayed, but there is a yellow exclamation mark in front of its listing, then there is a conflict with some other system device. Consult Solution 2 for troubleshooting conflicts.

Solution 2: Your scanner's SCSI card uses an interrupt request (IRQ) and input/output memory address (I/O). Occasionally, Windows' plug-and-play function will assign an IRQ or I/O address that is being used by some other device in your system. When this happens, your SCSI card will have a yellow exclamation mark in front of it in the Windows 95/98 Device Manager. Using the Device Manager, you can choose new settings for the IRQ and I/O address that may not conflict.

Follow these steps to enter the Device Manager and change the IRQ and I/O address settings.

1. Click on Start and select Settings.
2. Under Settings, select Control Panels.
3. In the Control Panels window, double-click on the System icon.
4. In the System window, click on the Device Manager tab.
5. Scroll down the list of devices until you see the SCSI Controllers section.
6. Click on the plus sign (+) and then double-click on the Adaptec AVA-1502 SCSI Host Adapter. NOTE: This is the card supplied with your scanner. If you are using a different card, you will need to consult with the manufacturer of that card for changing the settings.
7. In the Properties window for the AVA-1502 card, click on the tab called Resources.
8. In the Resources window, locate the check-box called "Use Automatic Settings."
9. Click on the checkmark to remove it, and some other choices will appear, including one called "Settings based on."
10. In the box following "Settings based on," you will see a listing like: Basic Configuration 0001. This represents the settings you are currently using. To change these settings, simply click on the down arrow. A list of more Basic Configurations with the numbers 0000 through 0007 will be displayed (you will have to scroll up and down to see them all).
11. Choose one of the seven settings configurations. As you choose them, check the box at the bottom of the Resources window called Conflicts. If any of the settings you choose are in use by another device, the name of that device will be displayed in this window. Repeat this step until the window reads "No conflicts."
12. Press the Okay button at the bottom of the Resources window to save the new settings. Close the Device Manager and restart your computer. Your SCSI card should now appear in the device manager with no conflicts.

2. Problem: The computer keeps finding new hardware every time Windows 95/98 is started and the scanner appears in the Device Manager with a yellow exclamation mark in front of it.

Cause: Windows' automatic hardware detection finds the scanner and adds it to the Device Manager, but it does not have the necessary information to list the scanner under its own category, and therefore places it under Other Devices. Because this entry information is incomplete, an exclamation mark appears in front of the entry and Windows will re-detect the device on every start up.

Solution: While it is possible to skip or ignore Windows' reminders about the scanner on every boot-up, it is recommended to download the file below that will create a proper Device Manager entry for your scanner and end the tedious reminder messages.

Click here to download the SCSI Scanner Device Manager entry file.

After downloading this file, click on its name to run the self-extracting program. IMPORTANT: The file includes a Read Me document providing instructions for proper installation. Make sure to read and print out this Read Me file.

3. Problem: The scanner is locking up after clicking on "acquire," during prescans or is returning the error message "TWAIN error: error opening data source due to unknown causes."

Cause: This problem is caused by compatibility issues between the TWAIN driver and certain versions of a file called WINASPI.DLL. The TWAIN driver versions found on the TWAIN update floppy version 1.5 and the 1200 A3 Pro CD with the part number 95-000-20481 Rev. 1.2 cannot use updated versions of the WINASPI.DLL file. In some instances, this problem is caused by a conflict between the TWAIN driver and Adaptec Direct CD writer software loading in the Windows 95/98 registry.

Solution: The 1.0 version of WINASPI.DLL must be active in the system for the TWAIN driver to work. In many cases, when the WINASPI.DLL has been updated, the original versions are still saved in the system under a different file extension, such as WINASPI.BAK. Follow the steps below to search for different versions of the WINASPI.DLL file and rename them accordingly. NOTE: Users who have Adaptec Direct CD writer software may wish to examine Step Three of the instructions for removing this software from the Windows 95/98 registry.

Step One - Using the Find command to locate all versions of WINASPI.DLL.

1. Configure Windows to display all file types.

1. From the Desktop, click on the icon called "My Computer."
2. In the "My Computer" window, click once on the C:\ icon to highlight it.
3. Click on View and select Options.
4. When the Options window appears, click on the View tab.
5. Click the radio button in front of the Show All Files option. Put a checkmark in the box labeled "Display the full MS-DOS path in the title bar."
6. Click the OK at the bottom of the Options window.
7. Close the "My Computer" icon.

2. Click on Start and select Find. From the menu choose Files or Folders.
3. When the dialog box appears, type "winaspi.*" (without the quotes) in the space called Named.
4. Click on the Find Now button.
5. The Find File window will now display all the files beginning with "winaspi."
6. Use these steps to check the version of each WINASPI file.

1. Highlight the first file by clicking on it once.
2. Click on the File menu and select Properties.
3. In the Properties window, click on the tab called Version.
4. Note the version number of the file.
5. Repeat these steps until you find the 1.0 version of WINASPI or you've checked all the files.

7. Once the WINASPI file version 1.0 is found, it will need to be renamed WINASPI.DLL so that it can be active in the system. Proceed to Step Two for instructions on renaming the files. If none of the WINASPI files were version 1.0, then you will need to download the file or call our Customer Service Department to request a copy on disk. You will still need to rename the currently active version of WINASPI.DLL before installing version 1.0.

Step Two - Renaming the WINASPI files.

1. After finding all the versions of WINASPI, as outlined in Step One, it is now necessary to rename the files to make the WINASPI version 1.0 the active file.
2. In the Find File window, click and highlight the current active file called WINASPI.DLL.
3. Click on the File menu and select Rename.
4. A small window will surround the highlighted file. Click in the window to place a blinking cursor at the end of the file name. Use your BACKSPACE key to remove the DLL from the filename.
5. Type in MSK where the DLL used to be and press ENTER. The filename should now read winaspi.msk" (without the quotes). Make sure that the period is still in place between winaspi and msk.
6. Click once to highlight the WINASPI.BAK file that we identified as version 1.0 in Step One. Reminder: If you didn't find a version 1.0 winaspi file in Step One, you will need to download the file or call our Customer Service Department to request it.
7. Click on the File menu and select Rename.
8. When the small window appears around the filename, click your cursor behind the name and use your BACKSPACE key to remove the BAK from the filename.
9. Type in DLL where the BAK used to be and press ENTER. The filename should now read "winaspi.dll" (without the quotes). Make sure that the period is still in place between winaspi and dll.
10. Close the Find File window. Click on Start and select Shut Down. Click the radio button in front of the "Restart the computer" option and click Yes.
11. After the computer restarts, try scanning again. The scanner should now work. If you encounter further problems, consult the other FAQ categories or call Mustek Technical Support. Users who have the Adaptec Direct CD writer software should proceed to Step Three. NOTE: Only those users who have a CD-ROM writer using the Adaptec Direct CD writer software should proceed to Step Three.

Step Three - Keeping the Adaptec Direct CD writer software from starting in the Windows 95/98 registry. REMINDER: Do this step ONLY if you have a CD-ROM writer using the Adaptec Direct CD writer software. If you do not have a CD-ROM writer, this step is unnecessary. If you have a CD-ROM writer, but are unsure if it uses the Adaptec Direct CD software, follow steps One and Two and then try your scanner again. If you still encounter problems, attempt Step Three.
