1. Selecting the proper scanner when installing the Scanner Solutions CD.

Cause: The Scanner Solutions CD contains the TWAIN drivers and software for about 10 different Mustek scanners. During installation, the default selection begins near the top of the list of scanners on a model which may or may not be the one you are installing.

Solution: Before clicking on NEXT, you must verify that the scanner selected matches the model scanner you are installing. Refer to the scanner model as it appears on the scanner’s box or the front nameplate. You can also refer to the chart below to verify which model scanner you have.

Step One: Identify which version of the Scanner Solutions CD you have.

There are two common versions of the Scanner Solutions CD, 1.2 and 1.3. To know which version you have, look at the lower left-hand corner of the cardboard jacket that the CD came in. You will see a part number (PN) and then a version number (Ver.). Click here if you have version 1.2 or click here if you have version 1.3.

You may also have a CD called Scanner Driver & Application Software with a red and blue striped cover. This CD only features two drivers: Plug-n-Scan 600 II EP or Plug-n-Scan 800 II EP. You will want to choose the 600 II EP option.

Scanner Solutions Ver. 1.2

Scanner Solutions Ver. 1.3

2. During installation, the error message: "Make sure 1. The Scanner is turned on. 2. The cables are connected. 3. The Scanner is set up correctly and card address does not conflict with other devices."

Cause: The 123 error message indicates that the TWAIN driver cannot locate the scanner's interface card. Since the 600 II EP uses a parallel port interface and NOT a SCSI card, this message means that the incorrect driver was chosen during installation of the Scanners Solutions CD.

Solution: Re-install the Scanner Solutions CD making sure to choose the proper scanner model. Refer to Problem 1 for help on identifying your model.

3. Error message: "Flatbed Scanner Not Ready."

Cause: During a scan, the following error message appears::

This error message occurs if the driver is unable to communicate with the scanner, or if the scanner is not powered on.

Solution: It is very important that you make sure that the connections are right, that the scanner is getting power, and that the parallel port is set to the proper mode for the scanner. Try the following troubleshooting steps:

1. The green LED light on the scanner needs to be solid green in order for the scanner to be ready. The light will blink if the scanner is initializing, as well as during or after a prescan or scan. After scanning or turning on the scanner, wait a minute for the light to stop blinking.
2. If the green LED never stops blinking, look at the rear panel of the scanner for two dipswitches on a small blue switchbox set in the case near the cable connector. These are diagnostic switches which need to be in the UP position (towards the lid) in order for the scanner to operate. Make sure both switches are pushed UP and then turn of the scanner and turn it back on again to let it re-initialize.
3. Disconnect any printers or other parallel port devices from the scanner and connect the scanner directly to the parallel port by itself. This will determine if the error is coming from the scanner, or from a conflict with another device.
4. Make sure the power cord is plugged in and the outlet is working. The green LED and a white internal light will both be on if the scanner is getting power.
5. Check the cable connections in the back of the scanner and the computer to make certain they are tight. Verify that you are using the IEEE 1284 cable that came with the scanner and that it is connected from the port labeled "Host" on the rear of the scanner to your computer's parallel port.
6. Set the parallel port mode to EPP in the computer's BIOS. This solves many problems with parallel port scanners. For more information on the EPP mode, click here.
7. If you have a parallel port Iomega Zip Drive, the drivers for this device may cause the scanner not to function correctly even if the Zip drive has been disconnected. For detailed instructions on configuring the scanner and the Zip drive, click here.
8. It is possible to have a "Scanner Not Ready" message caused by a software conflict. Try operating the scanner in Safe Mode in a program like iPhoto Plus 1.2. If the scanner operates in Safe Mode, you are most likely experiencing a conflict with a software program loading in Windows. For information on booting into Safe Mode (Windows 95/98 only) click here.
9. If the computer does not have an EPP mode (some old 486s don't), we suggest that you do one of the following:

1. (Easy) Get a scanner like the 1200 III SP which attaches to a 16-bit ISA SCSI card that comes with the scanner.
2. (Difficult -- Only for users familiar with IRQ/DMA Issues) Purchase an enhanced parallel port interface card such as the SIIG Parallel Pro Enhanced Parallel Port.
   Note: If you choose to buy a second parallel port and experience difficulty installing it, you must contact the manufacturer of the card if you need help with installation or configuration.

4. Printer problems.

Cause: Scanner works fine, but printers plugged into the port on the back of the scanner return error messages that "communication has failed," or that they are "out of paper" or will just not respond at all. The printer works fine, however, when not attached to the back of the scanner.

The Mustek Plug-n-Scan 600 II SP (600 II EP) does not support bi-directional print mode on its built in pass-through printer port.

Solution: If your printer does not print properly when attached to the scanner's pass-through port, you may be able to disable the bi-directional printing in your printer's driver.

5. A Fatal Exception Error occurs during installation of the TWAIN driver, or Fatal Exception Errors occur during scanning.

Cause: Fatal Exception Errors are usually caused by conflicts between programs that run simultaneously. To see a list of programs currently running on your computer, press the CTRL + ALT + DEL keys simultaneously. One or more of the listed programs are preventing the TWAIN driver from installing or running properly.

Solution 1: If the Fatal Exception Error is occurring during the installation of the TWAIN driver, then it is best to install the TWAIN driver in Windows 95/98 Safe Mode so as to temporarily disable the software that is causing the conflict.

Steps to install the TWAIN driver in Safe Mode:

1. If installing from the Scanner Solutions CD, you must copy the contents of the CD to your hard drive before you boot in Safe Mode because your CD-ROM drive will not operate in Safe Mode. Here are the steps to do this:

1. Insert the Scanner Solutions CD in your CD-ROM drive.
2. Click the Start button and choose Programs, then start the Windows Explorer.
3. Locate the icon for your CD-ROM drive in the LEFT window of the Explorer and double-click it.
4. Highlight the Setup95.exe file as well as all of the folders in the RIGHT window of the Explorer. You don’t need to select Tbcl96.31, Tbcladoc, Setup31.exe, Setupmac.exe or Start.wav files. Holding down the CTRL key will allow you to select more than one item.
5. Click open the File Menu and select Copy then close the Explorer.
6. Using the RIGHT mouse button, click in the lower portion of your Desktop. From the Pop-up Menu, select Paste. The files needed to install Scanner Solutions in Safe Mode will now be copied to your Desktop. You may drag them to the Recycle Bin after installation is complete.

2. Reboot your Computer in Safe Mode. Here are the procedures to do this:

1. Click Start and select Shutdown.
2. Highlight "Restart The Computer?" then click Yes.
3. Your computer will shutdown then restart. During the restart, you will see a message on the screen that says "Starting Windows 95 (or 98)..." When you see this message, hold down the F8 key until you see the Windows Startup Menu. For more information on booting into Safe Mode, click here.
4. Select "3. Safe Mode" and press the Enter key on your keyboard. Your computer will now begin to boot in Safe Mode. Be patient as it takes longer than a normal boot.

3. Now that you are in Safe Mode, you may install the TWAIN driver from floppy disk or from the Scanner Solutions files that were copied to your Desktop. To install from floppy, click Start and select Run then type A:\install and click OK. To install from the Scanner Solutions files on your Desktop, double-click the Setup95.exe icon. Use the Windows 95/98 File Finder to locate the Setup95.exe file if it does not appear on your Desktop. Here are the steps for using the File Finder:

1. Click Start and select Find, Files or Folders.
2. In the Named Dialog Box, type SETUP95.EXE and click Find Now.
3. Once the File Finder locates Setup95.exe, double-click it and the install program will begin to run.

4. After installing the software, restart your computer in Normal Mode. If you still have trouble scanning, proceed with the steps outlined in Solution 2 for simplifying your Windows 95/98 startup configuration.

Solution 2: When a Fatal Exception Error occurs during scanning, the best solution is to reduce the number of programs that automatically run when you start Windows 95/98. This procedure is more complex than booting in Safe Mode but will make your system more stable in the end.

Steps to simplify startup configuration in Windows 95/98:

1. Click the Start button and select Run.
2. Type SYSEDIT and click OK. This opens the System Configuration Editor which is a simple word processor. Each of your system files will be open in it’s own window.
3. Close the Autoexec.bat file without making any changes to it.
4. In the Config.sys file, locate a line containing the following:
   DEVICE=C:\WINDOWS\HIMEM.SYS (there may be additional text here)
5. Type the word REM and one space in front of this line as below:
   REM DEVICE=C:\WINDOWS\HIMEM.SYS.
6. Still in the Config.sys file, locate a line containing the following:
   DEVICE=C:\WINDOWS\EMM386.EXE (there may be additional text here).
7. Type the word REM and one space in front of this line as below:
   REM DEVICE=C:\WINDOWS\EMM386.EXE.
8. Click on the File Menu and click Save, then close the Config.sys file.
9. In the Win.ini file, locate a line that says:
   RUN=
10. If there is anything after the equal sign, type the word REM and one space as you did above.
11. Still in the Win.ini file, locate a line that says:
    LOAD=
12. If there is anything after the equal sign, type the word REM and one space as you did above.
13. Click on the File Menu and click Save, then close the Win.ini file.
14. Click on the File Menu and click Exit.
15. Next we will empty the Startup Program Group.
16. Using the RIGHT mouse button, click Start, then click Open and the Start Menu folder will open.
17. Double-click the Programs folder and it will open.
18. Open the Program folder’s File Menu and select New, then Folder.
19. Name the new folder OLD STARTUP then press ENTER.
20. Double-click the Startup folder and press CTRL + A to highlight all of the items in it.
21. Open the Edit Menu and select Copy.
22. Open the Old Startup folder that you just created.
23. Open it’s File Menu and select Paste. The contents of the Startup folder should now be in the Old Startup folder.
24. Double-click the Startup folder and press CTRL + A to highlight all of it’s contents.
25. Press the DEL key and confirm deletion of the items in the Startup folder. These programs will no longer automatically load when you boot your computer. If you wish to undo this later, reverse the above process to move them from OLD STARTUP back to Startup.
26. Close all folders and restart your computer.
27. You may now install the software in accordance with the installation instructions included with your scanner.

NOTE: If you ever need to call your computer manufacturer’s Technical Support line, inform them of the changes you made to the system. Below is a summary of the changes made:

1. Disabled HIMEM.SYS and EMM386.EXE in the Config.sys file.
2. Disabled RUN= and LOAD= lines in the Win.ini file.
3. Emptied the Startup Program Group.

6. Error message: "Cannot Find Wing32s.exe" or "Cannot Find Mustek.scr."

Cause: Some versions of the Scanner Solutions CD install a 32-bit Windows 95/98 screen saver. If you have Windows 3.1 and do not have a special utility from Microsoft which allows 32-bit screen savers to run in Windows 3.1, you will get one or both of these error messages.

Solution: Delete the Mustek Screen Saver. Here are the steps:

1. Open the Main Program Group and double-click the Control Panel icon.
2. Inside the Control Panel, double-click the Desktop icon.
3. Under Screen Saver, choose any screen saver besides the Mustek one.
4. Save and exit the Desktop and the Control Panel.
5. Open the File Manager and delete a file called C:\windows\mustek.scr

If you re-install Scanner Solutions in the future, you will need to repeat these steps.
