1200 A3 Pro FAQ (Frequently Asked Questions) for Macintosh 1. Error message: "TextBridge has unexpectedly quit because an error of type 12 occurred." 2. The Mustek Calibrator does not function. 3. There is no Mustek scanner listed under Scan/Import in Color It!. 4. TextBridge will not let me select Scanner on the setup screen. 5. Error message: "Scanner not found, please check the SCSI I.D." 6. A TWAIN window appears every time I boot-up my Macintosh.
1. Error messages: "TextBridge has unexpectedly quit because an error of type 12 occurred." Cause: This error message occurs while using TextBridge Classic. The original ISIS driver for the scanner contained an error that would cause it to lock up during the scan. Solution: There is an updated set of Scan Tools drivers that correct this problem. Click here to download them.
2. The Mustek Calibrator utility does not function. Cause: When trying to use the Mustek calibrator, the error message: "An error occurred when opening the data source, please install the 'Mustek Plug-in' and 'Mustek Calibrator'!" Solution: The original Calibrator utility did not function properly. Click here to download the updated, corrected version.
3. There is no Mustek scanner listed under Scan/Import in Color It!. Cause: The Mustek scanner is not present under the Scan/Import selection in Color It!. Solution: The plug-in is not properly installed in the Color It! program. The "Paragon 1200 A3 PRO" plug-in must be installed into the Plug-ins folder in the Color It! Stuff folder. - Double-click on the Color It! folder.
- Locate and double-click on the Color It! Stuff folder.
- Locate and double-click on the Plug-ins folder.
The Plug-ins folder should contain an item called "Paragon 1200 A3 PRO" and a "ColorSync Filter." These plug-ins need to be in the Plug-ins folder in order for Color It! to recognize them. If you do not see these items, check the following: - Make sure the plug-ins aren't in a different folder. From the Finder you can click on File and Find. In the Find window, type in Mustek to see all files with Mustek in the name. Under the File Type category, plug-ins will be listed as Adobe PhotoShop documents.
- Make sure the plug-ins are not in a folder within the Plug-ins folder. If they are, then Color It! will not be able to recognize them. They must be in the Plug-ins folder only.
- Make sure you don't have multiple copies of Color It! in different locations on your hard disk. One copy may have the plug-ins correctly installed, and the other may not.
4. TextBridge will not let me select Scanner on the setup screen. Cause: The TextBridge program setup screen does not have the option for Scanner under the Input section or the program displays a message saying it cannot find the scanner. Solution: TextBridge has not been linked with the scanner ISIS driver. Follow these steps: - Click on the Apple menu in the upper-left corner and select Chooser.
- Locate the Mustek ISIS driver icon. This will usually look like a green Mustek "M" or a scanner and be called Mustek A3 Scan. Double-click it. Note: Unlike a printer connection, nothing will appear in the information window on the right-hand side of the screen.
- Close the Chooser.
- Click the File menu and click Select Source.
- The TextBridge source window will appear with the name of the ISIS driver as the only choice. Click the OK button.
- The Input box will now have "Scanner" selected.
5. Error message: "Scanner not found, please check the SCSI I.D." Cause: When the Prescan or Scan buttons are clicked, a message is displayed that reads "No Scanner Found, Please Check the SCSI I.D." Solution: There are several reasons this error message can occur. The most common are On & Ready, SCSI I.D. #, Chain Placement, Cabling and Termination.
On & Ready
"Scanner not found" can occur if the scanner is not powered on and ready before the Prescan or Scan buttons are pressed. The scanner should be turned on and initialized before booting up the Macintosh, thus ensuring that the Mac's SCSI bus can identify the scanner as part of the SCSI chain. After being powered on, the scanner will run through an initialization during which the green LED light on the front will blink rapidly while the carriage inside the scanner moves back and forth at the rear of the bed. When the carriage moves into the starting position at the top of the bed and the green LED becomes solid, the scanner is ready. During scanning, the green LED will blink or turn off until the scan or prescan is complete, and then return to solid green. If the Prescan or Scan buttons are clicked before the scanner has a chance to reset itself, the "Scanner not found" message will appear. SCSI I.D. #
All items in a SCSI chain are identified by a SCSI I.D. number. This number is usually set by a dial or switch on the unit. On most Macintosh computers, there are certain I.D. settings that cannot be used. They are: 0 -- Is used by the internal hard disk.
3 -- Is used by the internal CD drive.
7 -- Is used by the internal logic board. Two devices sharing the same SCSI I.D. number could cause lock ups or the "Scanner not found" error message. Your Mustek scanner has a SCSI I.D. selector dial located on the rear of the unit near the cable connector. This dial is preset to 6 at the factory. In most cases, this dial will not need to be changed unless you have another device using SCSI I.D.# 6. Follow these steps to change the SCSI ID: - Turn off the scanner and shut down the Macintosh.
- Locate the SCSI ID dial.
- Use a small flat-head screwdriver to turn the dial to the desired setting. (Numbers 8 and 9 on the dial are for testing only and cannot be used.)
- Turn the scanner back on and wait for it to initialize. Boot the Macintosh when the scanner is ready.
Chain Placement
It is best to have the scanner as the last item in a SCSI chain, though occasionally other devices between the scanner and the Macintosh will cause the "Scanner not found" message. Try disconnecting other SCSI devices and using the scanner by itself. If the scanner works, you may need to rearrange your SCSI chain with the scanner in front of the conflicting device. Cabling
When chaining devices together, try to use the cable supplied with the scanner to link it to your Macintosh or other SCSI devices. This cable has the number 20276 written along the side. If you are getting a "Scanner not found" message, remove any adapters or third party cables and try the scanner with the original cable. If you find that you need to use different cables or adapters, make sure they are rated for SCSI devices, otherwise they may create signal loss. Termination
When running a Mustek scanner as the only device on the SCSI port of a Macintosh, no other termination should be necessary. If you are using the scanner with an older model Macintosh that does not have internal termination (check your user's guide), or if you have the scanner at the end of a multiple-device SCSI chain, you can use the terminator supplied with the scanner.
6. A TWAIN window appears every time I boot-up my Macintosh. Cause: The 1200 III SP installation CD-ROM installs a TWAIN source manager into the Startup Items folder. This is unnecessary because the 1200 A3 Pro uses versatile plug-ins in Macintosh instead of TWAIN. Solution: Follow these steps to remove the TWAIN folder from the Startup Items folder. - Double-click the hard disk to open it.
- In the hard disk, locate the System Folder and double-click it.
- In the System Folder, locate the folder called Startup Items. Double-click it.
- In the Startup Items folder, locate the folder called TWAIN. Click on the folder and drag it to the Trash.
- Close the Startup Items folder and the System folder. When you next boot-up, the TWAIN window will not open on the Desktop.
