Selecting Correct Scanner Model When Using Scanner Solutions CD
Flatbed Scanners With A SCSI Interface
Make sure that you are using the 5' or 6' SCSI cable that came with the scanner.
SCSI devices are very dependent on signal strength and timing.Using longer cables
changes the signal strength and timing and will frequently prevent the scanner from
functioning normally. Exceeding 10' cable length is not advisable in any case. If you
are using a different cable, try the Mustek cable to see if it will work. Mustek's
cables have the number 20276 printed on the cable. If you must have a longer cable,
contact Precision Cable at (503) 222-4323. Precision Cable manufactures a variety
of cables to individual order. They are familiar with Mustek's product line.
Plug-N-Scan Series Scanners
Using third party cables with the Plug-N-Scan series scanners may degrade the
signal strength and therefore the image quality. There are many cables available from
retail vendors that have the same type of connectors as the Mustek cable, but do not
have the same pinouts and will not work at all. If you need a longer cable, make sure
you get one that conforms to the IEEE 1284 specification.
The cables supplied by Mustek comply with FCC regulations. If you use a different
cable, responsibility for ensuring compliance with FCC regulations becomes yours.
Mustek owners have successfully installed their scanners using a variety of third party
SCSI cards; however, Mustek's Technical Support Department does not provide
expertise on installation of SCSI cards that did not come from Mustek. If you are using
a third party SCSI card and need help with it you must call the manufacturer of your . SCSI card. If you call Mustek for assistance, please have a Mustek supplied SCSI
card installed in your computer at the time of your call.
PC With Windows
Mustek's scanners do not require a SCSI terminator when used by themselves. If
you attach the scanner at the end of a SCSI chain, you must attach a Passive SCSI
terminator to the second SCSI port on the back of the scanner. Since Mustek's
proprietary SCSI cards do not support additional SCSI devices, SCSI termination is
only necessary when using the scanner with a third party SCSI card on a PC. See
above paragraph for info on Third Party Cards.
Macintosh
Mustek scanners do not need to be terminated if they are used by themselves
regardless of what the scanner user's manual might say. If you attach the scanner to a
SCSI chain, it will require a terminator if placed as the last device in the chain.
If your installation parameters require a SCSI terminator, contact our Customer
Service Department to obtain one free of charge.
If your scanner attaches to a SCSI interface card, it will have a small yellow dial on the back that is used to set the scanner's SCSI I.D. #. It should be set to #6. Each device attached to a single SCSI controller must have a unique I.D. #. If another SCSI device on your system is set to #6, you must change the scanner's I.D. #. This situation is rare and usually only happens on Macintosh computers. If you have SCSI I.D. problems on a Macintosh, try setting the dial to #4.
Removing Previous Twain Drivers
It is possible to attach more than one Twain compliant device to a computer. All Mustek scanners are completely compatible with each other, so you can attach several of them to one machine. Other brands of Twain compliant devices occasionally interfere with the installation of a Mustek scanner. Additionally, some computers come with Twain drivers pre- installed even though they don't come with a Twain device. Below is a list of computers and Twain devices known to cause problems with the installation of Mustek scanners. Twain devices are items such as Scanners, Digital Cameras and Video capture devices such as Snappy. If you have more than one Twain compliant device, you may need to remove the Twain driver for the other device and then re-install it after you have installed the Mustek Twain driver.
When attaching multiple Twain devices to a computer, it is necessary to configure your Host Application for the device you wish to use. A Host Application is the Twain Compliant software that you scan into. Some examples are: iPhoto Plus, Picture Publisher, Text Bridge Classic, Wordlinx, Corel Photo Paint and Adobe Photoshop. Instructions for Deleting Twain Drivers and for Configuring The Host Applications given below.
Hewlett Packard Computers
Hewlett Packard computers frequently have a driver pre-installed for the HP Photo
Reader scanner even if the Photo Reader did not come with the computer. If you do
have a Photo Reader, it is compatible with your Mustek Scanner. All you need to do
is follow the instructions below to Configure your Host Applications.
Hewlett Packard Printer Owners
Owners of Hewlett Packard Printers sometimes have the HP Photo Reader Twain
driver installed on their hard drive. Apparently the Photo Reader Twain driver is
installed at the same time you load your HP printer driver. If you do not own the
Photo Reader, delete it's Twain driver as explained below.
Packard Bell Computers
Many Packard Bell computers come with a driver pre-installed for the Top Drawer
Scanner. If you own the Top Drawer scanner, it can be used in addition to your
Mustek scanner. Just follow the instructions below to configure your Host
Application. If you don't have the Top Drawer scanner, you should delete it's Twain
driver prior to installing the Mustek Twain driver.
Snappy Video Capture Device
Owners of Snappy occasionally have difficulty installing a Mustek scanner. The
solution is to delete the Snappy Twain driver before attempting to install the Mustek
Twain driver. After the scanner is installed successfully, you should then re-install the
Snappy Twain driver.
Deleting Twain Drivers
Twain drivers are stored in files with a .DS file extension.They are usually located in
the C:\windows\twain directory on your hard drive. Use the windows 3.x File
Manager, the Windows 95 Explorer or MS-DOS commands to delete any file with
a .DS extension.
he following commands executed from an MS-DOS prompt will usually delete all . Twain drivers including the Mustek driver:
CD\
Deltree C:\windows\twain*.*
Deltree C:\windows\twunk*.*
Configuring The Host Application
When you have more than one Twain device installed on your computer, it is
necessary to select the Twain source for the device you wish to use. Most Twain
compliant Host Applications have a Select Source command on the file menu. Some
Host Applications have a Setup/Scanner option and others have a Select Acquire
Device option. If using third party scanning software not supplied by Mustek, refer to
the program's manual if you are unable to find the Select Source menu command.
Once you have found the appropriate menu command, a Twain Source List will
appear on your screen showing all installed Twain drivers. Select the Mustek scanner
from the list. If there is more than one Mustek scanner listed, you installed more than
one Twain driver from the Scanner Solutions CD.
Mustek updates Twain drivers frequently in order to ensure compatibility with an ever changing variety of scanning software. If you are having difficulty installing the Twain driver that shipped with your scanner, you should visit our Driver page and download the latest driver for your scanner. If you are unsure what driver version number you are using, acquire your scanner through iPhoto Plus or Picture Publisher. The driver version number will be on the Title Bar of the
scanning window.
Selecting Correct Scanner Model When Using Scanner Solutions CD
The Scanner Solutions CD ships with every scanner that Mustek makes. We currently make about 10 different models. The Twain drivers for all of them are on the Scanner Solutions CD. You must choose the correct model scanner when installing the Scanner Soultions CD or your scanner will not operate.
Setting The Scanner Card's I/O Address
If your scanner came with a SCSI interface card, you must have an I/O port address available for the scanner. If the address set for your SCSI card is in use by another device in your computer, you will get the following error message:
you have a Plug-and-Scan series scanner and get the above error message, it is because you did not select the proper scanner model number when installing the Scanner Solutions CD. Mustek flatbed scanners do not use IRQs or DMA channels with the exception of the Paragon 1200 SP Pro which requires an IRQ. The 1200 SP Pro comes with a Plug and Play Adaptec 1502P SCSI Card which will automatically set the I/O address and IRQ level for you.
The very old AX SCSI Cards are not compatible with Mustek's 32-bit Windows 95 Twain
drivers. If you have an AX SCSI card, you must purchase a new DTC SCSI card from Mustek's Customer Service Department in order to use 32-bit Windows 95 scanning applications. The old 16-bit Twain drivers that came with your scanner should work in Windows 95 with the16-bit applications that came with your scanner.
AZ SCSI Cards have an address switch which is used to set the I/O port address for the scanner. If you are installing Twain driver version 3.4 or later for a Single Pass scanner, you must set the card's I/O address in two different places. First, set an available address on the card using the three switches. Then set the exact same address on your computer's monitor during installation of the Twain driver version 3.4 or later.
The newer DTC SCSI Cards allow the address to be set during installation of the driver by
selecting an address from a list appearing on your computer's monitor. For more detailed instructions on setting the address for your SCSI card, click the link below to see Document # 301 - Interface Card Issues.
