Checklist-— Before you begin

Your Nikon Scanner may be supplied with a combination of manuals, soft- ware and accessories. The exact contents will vary from country to country and in accordance with the particular configuration offered by your supplier. However, you should make sure that you are in possession of the following items before you start (and before your local computer shop closes for the evening or weekend!)

1. An AC power cable All Nikon scanners are fitted with an IEC AC inlet connector. The scanners are dual voltage and will accept supplies from 100 to 240V AC.

Nikon Scanners use the “SCSI” standard for connection to your computer. SCSI cables are available in a variety of configurations. For example, there are at least three common types of SCSI connector. Y ou will need a cable that is correct for your particular equipment set-up. See the description of SCSI connectors on page 16.

A SCSI cable with 50 pin and 25 pin SCSI connectors

3. A SCSI adaptor If you have a Macintosh computer, SCSI is fitted as standard (it is the 25-pin D-type connector on the rear of the computer marked ©.

Windows 3.x and 95 users will need to fit a SCSI adaptor card to their PC to allow connection to the Scanner. Nikon cannot guarantee the operation of the scanner with SCSI adaptor cards that have not been tested and approved (a list of tested cards is included in this envelope). There may be an approved SCSI adaptor card provided with your scanner.

4. À SCSI terminator Up to seven devices can be connected in series using SCSI. However, the longer the chain, the more prone it is to interference and instability. It is essential to end the chain with a terminator: this is a connector with no lead that contains circuitry to deaden the end of the SCSI circuit, thus d reducing interference and noise picked up by the cabling.

i SCSIT. inat The terminator may be connected to the spare erminators

socket on the last device in the SCSI chain. If this connector is of the wrong type for your terminator, try rearranging the order of the devices in the chain, or fit the terminator between the last device and the cable. For this type of connection you will need a terminator that has a connector at both ends.

Nikon scanners are usually provided with software. This may be Nikon’'s own product, or be from a third party. In addition there may be other software that has been included to provide additional functionality such as OCR and image manipulation packages.

Nikon Software is supplied on a Diskette or CD labelled Nikon Scan. This software is comprised of two parts:

6. Manuals In addition to this Fast Track guide, you may find a user manual for the scanner, and operator manuals for Nikon Scan and Nikon Control. The aim of this guide is to provide you with all of the information that you need during your first installation and scanning session. Please take care to read the other documentation to gain the most from your new equipment.

Now that you have checked that you have all of the required items, please turn to the next page to find out how to test and prepare your scanner.

Making the Perfect Installation: Installing a SCSI Adaptor

2. Installing a SCSI adaptor

Macintosh owners do not have to take this step as their machines are fitted with SCSI as standard. However, if you do own a Mac, whilst the PC owners are leaning about SCSI, now would be a good time to check the condition of your system and SCSI cables. See Part 4: Connecting the Scanner.

PC owners are faced with the more daunting task of installing and configur- ing a SCSI adaptor in their PC.

If you are a Windows 3.1/3.11 user, you will have to manually install drivers for your particular card. If you are a Windows 95 user, then the operating system does this for you, providing that you have a SCSI adaptor that Win- dows 95 recognises. Y ou will also need to ensure that your card does not interfere with any other devices that may be fitted to your PC such as sound cards, Video decoders etc.

Do not attempt to connect your scanner to your computer until you have successfully installed the SCSI adaptor card. If you attempt to connect your scanner before completing a correct SCSI card installation in the hope that it will somehow magically start to work, you will almost definitely fail.

The next pages will help you to complete your SCSI installation. Remember that it is impossible for Nikon, as a scanner manufacturer to be able to offer advice on all SCSI adaptors. However, the following page describes the principals that you should follow.

We would like to offer more help than just the usual “Refer to the manufacturer's information that came with your SCSI card.”

Making the Perfect Installation: Installing a SCSI Adaptor

Windows 3.1— SCSI Installation

SCSI adaptors cards are circuit boards that fit into the expansion slots inside your computer.

The card set-up will involve specifying certain parameters to allow the computer to communicate with the card. These parameters include, for example, interrupt (IRQ), port and memory address range. They are set on the card by some combination of jumpers, switches or through a software utility, and on the computer by adding lines to the config.sys file. The adding of lines to the config.sys file is usually done by an installation program that also copies the correct drivers to your hard disk.

Each card may have a different method of setting the values of the param- eters. The most important thing to remember is that the value that you set

AN must not conflict with other devices that are already installed on your com- puter. For instance if you set the SCSI card IRQ to 12, and your mouse happens also to use that number, then your card and mouse will probably stop working.

Check your computer thoroughly before starting by examining any fitted cards in expansion slots and confinming the allocation of resources in the config.sys file.

Step 1. Try to find out what resources are in use by your computer. This includes your mouse, network card, game port etc. Type “msd” at your system prompt to run the Microsoft Diagnostics program. Note the usage of port addresses, IRQs and memory addresses.

Step 2. Carefully check how to change the settings on your SCSI card. The popular AV A 1505 has labelling that is very misleading (see right): other cards may be similanly difficult to set up.

Step 3. With the power off, install your card into your PC.

Step 4. If you have an installation disk supplied with your SCSI card that will copy drivers to your hard disk and alter your config.sys file to load them at start-up, turn on your computer start Windows and run the setup program from the disk.

The SCSI installation must be completed successfully before continuing with the scanner installation.

Windows 95— SCSI Installation

When you install your card and power on the computer for the first time, Windows 95 will run a Hardware Wizard. This system helper detects the new hardware and finds a driver for your SCSI adaptor.

Any conflicts between the way that you have set up the card and the existing installed hardware will be announced for you to resolve (see opposite). If no conflicis are found, you will be presented with a choice of using one of the available drivers from Windows, supplying one from a manufacturer’s disk or quitting and running your own set up program from a manufacturer's install disk.

At least one of the three routes should be successful.

Do Nor connect your scanner until you have successfully completed SCSI installation as you will confuse yourself and the Windows 95 Hardware Wizard. Keep things simple and do one thing at a time.

When your SCSI card is installed correctly, your will see a SCSI symbol in the System Hardware profile windows. By checking though the Properties for the SCSI device, will be able to confirm that the it is working correctly.

E-@ PROTECTION Ë 2 SCSI contrallers

If the SCSI icon has a yellow “?” or “!” or a red “X” over it, a conflict is indicated, which you musr resolve before connecting with the scanner. See the troubleshooting section for hints and tips.

Step 1. Determine a free set of resources using the System Device Manager window.

Step 2. Set your SCSI card to match these values.

Step 3. Power off, install the SCSI card and follow the advice of the Hardware Wizard.

Windows 95 Nikon Scan

If you installed your SCSI adaptor successfully then you will be familiar with the Hardware Wizard. This useful helper will now try to prevent you from completing the next phase of the installation!

If you connect your Scanner to your SCSI card, the Hardware Wizard will try to install a driver for the scanner. However, scanners do not work in this manner, as they are temporary devices that only connect to the system when you call for a scan to be made. If you follow the Hardware Wizard your installation will almost certainly fail!

The secret is to install the software first. Disconnect the scanner from the computer if it is connected at this time.

If you have Nikon Scan or other software with “Setup” program on a disk, from the Start menu, select “Run” and the type A:\setup into the dialogue. This will ensure that you have a complete set of correct software fully in- stalled.

Windows 3.1 Nikon Scan

Software installation in Windows 3.1 or Windows 3.11 is a simple matter of inserting the disk and from the File menu, selecting “Run” A:\Setup. How- ever there are a number or reasons why, having installed the software and SCSI card, things might still not be working. The main reason is the overall lack of free resources and interdependence of drivers that is a feature of Windows 3.1 (something that Windows 95 has been designed to avoid). In particular, memory-resident drivers and programs for expansion boards such as sound cards, PCMCIA adaptors and network cards can cause memory problems that prevent the scanner from working. Lastly there may be shared files (one of the most common being winaspi.dil) that become replaced or updated by add-ons such as some parallel port-connected removable storage media. The new driver may not be compatible with the scanner.

The way to avoid such situations (as when connecting any new device to a PC running Windows 3.1) is to renew or update any suspect drivers that may have been overwritten by later additions, and to remove potentially conflict- ing devices and programs one at a time until the incompatibility is identified.

You should be able to find a combination that allows you to connect the SCSI cable between the computer and the scanner, and to fit a terminator at the scanner end. If there is no free socket on the scanner for the

terminator, use a “through” type terminator (has a connector on each end) between the cable and scanner at the scanner end.

Making the Perfect Installation

The final task is to set the SCSI ID number of the scanner.

A single SCSI chain can support up to 7 devices, some of which may be internal (hard disks, CD ROM drives). Each device has a unique identification number to ensure that the SCSI controller can communicate without ambiguity.

Although there are no fixed rules for SCSI, the general practice is to put the controller at ID 7, any hard disks at 0 and 1, and a CD ROM drive at 3.

This leaves 2, 4, 5 and 6 free for you to assign, unless you have additional devices installed. Nikon Scan- ners are usually set to ID 5 when shipped from the factory. The scanner ID is set by a switch on the rear of the unit. The switch may either be a rotary type or a push type.

Note that after changing the ID number, the unit must

be switched off and on for the new setting to be registered.

Don't forget to remove the last-used slide from a slide scanner before powering on again.

When things go wrong...

We’re very sony that you have arrived at this page as it means that things have not gone completely to plan!

Please bear in mind that if you have installed your system according to the

instructions in this booklet, if your scanner is working correctly and if your system is “clean”— meaning that it has no conflicting programs, devices or drivers loaded— then everything wizL work.

Please reread this manual and check through the steps of testing the scanner before it has been connected to the computer, verifying that your SCSI adaptor (if fitted) has been correctly installed and is of a type compatible with Nikon Scanners.

If you have completed the above suggested action, then our recommendation is to try the following:

1. De-install all Nikon software (see the appropriate procedure for your platform in the troubleshooting section.

2.a (Windows 95 users) Remove the SCSI controller and Nikon Scanners from the Device Manager.

2.b(Windows 3.1 users) Recheck your config.sys file for conflicting drivers. Back up the file and try to remove possible conflicts one at a time.

2.c (Macintosh/MacOS users) Restart the computer with the shift key held down to prevent system extensions from loading. If this works, disable extensions using the Extensions Manager to isolate conflicts.

3. Check that your system has the latest or known good SCSI drivers.

4. Check the SCSI cabling. A SCSI chain must be terminated at each end. Systems without internal devices (hard disk, CD ROM drive) should have termination set on the SCSI adaptor card. If your system has an internal device, this device should be terminated and the termination should be removed or disabled on the SCSI adaptor.

5. Has your system software become corrupted? A reinstallation may be necessary.

6. Follow this manual again, reinstalling SCSI drivers (PC users) and software.

1. De-installation and reinstallation of software

The following describes a complete reinstall of Nikon Scan software and SCSI card on a Windows 95 platform.

1: Remove the Hardware from the System.

Go to the My Computer icon on the desktop.

Double click on Control Panel.

Open System and you are presented with an index folder type window.

Select Device Manager from the tabs. A list of devices is shown.

Double click on SCSI controllers and then single-click on the particular device you wish to remove so as to highlight it (ex- ample Adaptec AHA-150X... … …).

Click on the Remove button at the bottom of the window and select OK. If prompted that Windows doesn't know whether it can remove the device safely select Test.

Follow the same method for removing your scanner from under the Nikon Scanner group.

If one or both of the devices was not present, check to see if there is any SCSI or scanner hardware listed under the category Other Devices. If so, remove it.

2: Remove the Nikon Software.

In the Nikonei folder, locate the Setup folder. Double click on the Uninst icon to uninstall the Nikon software.

If for any reason this does not complete successfully, then follow the procedure below:

In Windows Explorer delete the directory Nikonei.

Find the WINDOWS\TWAIN_ 32 direc- tory. If you have no other scanner or twain compliant devices this can be deleted. If you do have another scanner, remove only files from the TWAIN_32 directory starting with NK...

Delete the WINDOWS\MDMODS 32 directory.

Windows 3.X drivers Find the WINDOWS\TWAIN directory.

If you have no other scanners or TWAIN compliant devices this can be deleted. If you do have another TWAIN device, delete only the files starting NK.... Delete the WINDOWS\MAIDMODS directory.

3: Install the SCSI Card.

Ensure that your Nikon Scanner is discon- nected from your SCSI card (internal units) or switched off (external units).

Restart your computer.

If your SCSI card is a “plug and play” device, then Windows should detect it on restarting. Follow the on-screen instruc- tions.

If however it is not detected on restarting Windows 95 then open the My Computer icon on the desktop. Double-click on Control Panel then select Add New Hardware, click Next and let Windows 95 auto-detect your SCSI card.

Æ3 Control. Pfel E3 Elle Edit View Help

Adds new hardware to! Z Check in the Device Manager to make sure that the SCSI card has installed by confirming that the grey diamond SCSI icon is present and no devices are showing as conflicting. If there are conflicting devices, your SCSI card settings need to be changed and the card reinstalled. Follow the instruc- tions supplied by the SCSI card manufac- turer.

4: Install the Nikon Software.

Insert the floppy disk labelled “Nikon Scan for Windows 95” and then from My Computer, Control Panel, select Add/ Remove Programs.

Double-click on the Install button and follow the on-screen instructions.

5: Install the Scanner

Restart the computer with the scanner switched on and plugged in to your SCSI card.

Windows 95 should announce “new hard- ware detected”. Follow the on-screen instructions, but quit when asked to supply a disk (see page 18).

The following describes a complete reinstall of Nikon Scan software and SCSI card on Windows 3.1 platform. Before commenc- ing, make sure that you have your software installation disks.

1: Remove the Hardware from the System.

Open the System Editor (or type EDIT at the DOS prompt). Open or go to the Config.sys file.

Save a backup copy of this file as a precau- tion.

Locate the line which refers to your SCSI card. A typical example is: DEVICE=ASP2DOS.SYS followed by parameters such as “/P:330” etc.

You may have to study the manufacturers manual to find the correct line.

Put the characters “rem” in front of this line.

Save the Config.sys file.

Look in the WINDOWS\SYSTEM direc- tory for the files WINA SPI.DLL and VASPID.386.

Rename them WINASPI.BAK and VASPID.BAK.

2: Remove the Nikon Software.

In File Manager delete the directory NIKONEI.

Find the WINDOWS\TWAIN directory.

If you have no other scanners or TWAIN compliant devices this can be deleted. If you do have another TWAIN device, delete only the files starting NK... and rename the file TWAIN.DLL to TWAIN.BAK.

Delete the WINDOWS\MAIDMODS directory.

Delete the file Nikonctl.ini from the WINDOWS directory.

3: Install the SCSI Card.

Insert the installation disk that was deliv- ered with your SCSI card and run the install program. This is usually done by selecting Run from the File menu and browsing to the A: drive. The installation file is usually called “Setup.exe”

Check your config.sys file for any changes.

Y ou should see a new line that is identical to the line that you added “rem” to in Step 1. If not, then you have altered the wrong line, and should remove the “rem” as this

reference may be used by other hardware.

4: Install the Nikon Software.

Insert the floppy disk labelled “Nikon Scan for Windows” and then from the Program Manager, File menu, select Run and type “A:\setup”.

Click on the Nikon Control icon to start Nikon Control and in the File Prefer- ences dialog select Nikon Scan as the Twain source.

Launch Nikon Scan and verify that the scanner is performing properly.

If operation is correct, quit and delete all of the files that you renamed with a .BAK extension.

The following describes a compete reinstal- lation of Nikon Software on a Macintosh Platform.

1: Remove the Nikon Scan Plug-in

Go to the Photoshop Plugins folder and find the sub folder Import/Export.

Find the Nikon Scan plug-in and drag it to the Wastebasket.

Open the Preferences folder in the System folder locate the folder Nikon MAID. Drag this folder to the Wastebas- ket.

Whilst still in the Preferences folder, locate the Photoshop Preferences file and drag it to the Wastebasket.

Finally, locate the Nikon Control file and drag this to the Wastebasket.

Empty the Wastebasket and restart the computer holding down the shift key to disable extensions. Reinstall your software from the floppy disk(s).

Ensure that the following files are in the locations described:

* Nikon Scan Photoshop Plugins:Import{Export

+ LS-1000 module, LS-4500 module, AX 1Module System folder-Preferences:Nikon MAID

+ Nikon Control As desired.

Background: the need for updated SCSI drivers

As new SCSI peripherals appear on the market, SCSI adaptor card manufac- turers release new drivers to ensure connectivity to these new arrivals. However, some drivers then prove to be incompatible with existing devices and a further update is then devised and circulated. Likewise, the arrival of a new SCSI card type is often followed by a period of updating drivers as reports of overlooked devices are received from customers.

If you are experiencing problems with your Scanner, particularly if you have installed other SCSI devices on your system, then you may need to find and install updated drivers.

In order to simplify matters, Nikon Electronic Imaging supply and recom- mend A daptec SCSI adaptors, information about which can be found though the internet at http://www.adaptec.com and on Compuserve by typing GO ADAPTEC.

The particular driver that you require will depend on your SCSI card, and unfortunately the card type and driver are not called by the same name. The section below should help you find and identify the SCSI driver used in your system. However, Nikon cannot hold an exhaustive list of all drivers for all SCSI adaptor cards.

Shown opposite are typical examples of some SCSI installations to help you identify the best configuration for your system. If you are unfamiliar with the appearance of the three types of SCSI connector, see the photographs on page 16.

These suggestions assume that you have no existing SCSI devices. (If you do, then you are likely to already be familiar with how to interconnect devices).

Nikon strongly recommend the use of high quality SCSI cables wherever possible. Generally speaking, the thicker the cable the better, as a thick cable is likely to have better shielding against interference than a thin one.

Itis also recommended that the shortest possible cable length is used. Al- though when running at lowest speed (5Mbytes/sec), a total cable length of 8 metres is permissible, this figure drops to half as the SCSI speed is doubled.

4. Reinstalling system software

The Complex Nature of Computers

In all of Nikon Technical Support’s combined years of experience, we have never encountered a customer who is glad to receive the advice “you could try a reinstall of your system software”. However, it is a fact that as computers become more complex, and the number of applications and expansion oppor- tunities increases, the need for periodic system reinstallations becomes ever more a part of computer ownership. Often it is the arrival of a new peripheral or software package which provokes the need for this action.

Why should it be necessary to reinstall?

Computer manufacturers have realised that the more applications that get installed onto a system, the more possibility there is of a conflict arising. These conflicts often occur when an application loads a driver that it uses to gain access to a particular resource within the computer. Examples of these include direct video drivers, SCSI re-directors and cursor redraw plugins.

Such drivers are often hidden from the computer operator and may remain even when the original program or device has been removed.

Apple Computer, through the Extensions Manager and Microsoft with the Plug and Play bus enumerator have both attempted to make their operating systems “self healing” by allowing either manual or automatic removal of unused drivers and extensions. However, sometimes such measures are still not an adequate defence and after a while a hidden conflict develops, requir- ing the entire system to be torn down and rebuilt.

Another reason for a system reinstallation arises from System crashes. During normal everyday operation, the computer has loaded data, programs, drivers and preferences files into memory. If a system crash occurs, then these elements are often in an indeterminate state. They may be corrupted because they are in transition between volatile memory and the computer’s hard disk.

All computers can recover from a system crash, in the most extreme case by simply turning off the power and restarting. However any damage done to the software is not always obvious and the seemingly clean recovery could be hiding a problem which only becomes visible at a later date.

Therefore, when you are offered the advice “you could try a reinstall of your system software”, think carefully about the use that you have had from your

computer, and try to consider it as a good opportunity to have a complete and effective clean-up of your workstation.
