Introduction

Take Pictures. Further. Now you can use pictures in more ways than ever with the Kodak Digital Science(tm) Snapshot Photo Scanner 1 (Snapshot Photo Scanner). The Snapshot Photo Scanner is a fun and easy way to scan pictures and other items into your IBM PC or compatible computer.

You can use your scanned pictures in countless ways. Put pictures in your documents, newsletters, school reports, advertisements--you can use them just about everywhere! Create customized greeting cards and announcements. You can even e-mail pictures you scan with the Snapshot Photo Scanner!

Pass-through Port: The Art of Scanning or Printing

The Snapshot Photo Scanner's pass-through port is a really handy feature that allows you to scan and send your output to your printer with ease.

Note:	The pass-through port functions correctly only when the scanner's power supply is connected to the scanner and plugged into an electrical outlet.

You Cannot Do Two Things at Once

Of course, you cannot scan and print at the same time, because your computer still has only one parallel port. Follow these simple rules for scanning and printing:

-	Do not try to print when the indicator light on top of the scanner is brightly lit. (The light is bright when the Kodak scanner software window is open.)

-	Do not try to scan when you are printing. Wait until the printer has finished printing before you access the Kodak scanner software window.

Overview

This section describes how to use the Kodak scanner software to scan a picture or other item and save it or transfer it to your application. The Kodak scanner software provides two option modes, Step-by-Step and Expert. These modes are described in the section called More about the Kodak Scanner Software Window.

Click on the Step-by-Step button if you want to go through the scanning options window by window.
or
Click on the Expert button to access all scanning options on one window.

The Scan window appears.

The scanner lamp warms up in less than 40 seconds. You should wait until the lamp is completely warmed up before you can begin scanning your pictures.

Note:	The Scan button is not active until the item you are scanning is in place on the scanner.

You can specify a setting in the Preferences dialog that allows you to scan a picture before the lamp is completely warmed up. Scanning a picture before the lamp is warmed up results in a darker-than-normal picture. (Click on the Preferences button in any of the Kodak scanner software windows to access the Preferences dialog.)

Using Step-by-Step Mode

Use the Step-by-Step mode as you first learn how to scan your pictures with the Snapshot Photo Scanner and how to work with the picture-enhancing options of the Snapshot Photo Scanner software. These options are on four separate windows so you can easily step through them as you learn how to use the scanner and fix up your scanned pictures.

Note:	If you only want to scan and save a picture without enhancing it, you may skip over the second (Rotate/Trim) and third (Enhance Image) windows and go from the first window (Scan) to the fourth window (Save/Transfer).

The Step-by-Step mode has four numbered window tabs that represent the various options you have for scanning a picture and enhancing your scanned picture. Click on a window tab to access the options in that window.

For more information about the windows in Step-by-Step mode, click on a topic.

Frequently Asked Questions (FAQs)

Scanner Will Not Scan When Printing

The Snapshot Photo Scanner's pass-through port allows you to attach both the scanner and your printer to the single parallel port on your computer. However, you cannot scan and print at the same time.

For more information about the Snapshot Photo Scanner's pass-through port, refer to the section called Pass-through Port: The Art of Scanning or Printing.

Closing Open Applications Before Software Installation

You must be sure that all applications are closed before you install the Snapshot Photo Scanner software. Go to the application and pull down the File menu and select Exit. to close that application.

If you are using MICROSOFT OFFICE (tm): This application has a toolbar that appears on the desktop. This application runs in the background and does not always appear to be active. You must close the toolbar that appears on the desktop before you install the software on the CD.

Other applications (like video display tools, screen savers, and others) may also run in the background. You must close all of these applications as well.

Windows 3.1x:

These applications usually have icons that you can determine by using the ALT-TAB command sequence (see your Windows documentation for more information) or in other desktop locations and you may not always remember that they are active.

Windows 95:

These applications usually have icons that appear in the Windows 95 Start bar or in other desktop locations and you may not always remember that they are active.

If you do not close all applications, they can become corrupted during the Snapshot Photo Scanner software installation. If you have corrupted your applications, you probably will have to re-install the corrupted application(s) from the original software.

Picture Colors Do Not Look Right on the Monitor

Typical photographs contain millions of colors. A computer monitor can usually display 256, thousands, or millions of colors, depending on the monitor and the video display cards, and how the video display software is set up. So you may not be able to see the actual true colors of your scanned picture on your computer monitor.

The colors that monitors generate vary greatly among different manufacturers and monitor settings. Colors are more consistent on color printers. If the picture you scanned does not look good after printing (for example, if the entire image, including the white background, looks too green), run the Diagnostics software and recalibrate the scanner.

Information about recalibrating your scanner is in the section called Testing and Calibrating Your Scanner.

Printing Problems

If you have problems printing your scanned pictures, make sure that the scanner's power supply is connected to the scanner and plugged into an electrical outlet.

Scanner Lamp Is On After Computer Is Rebooted or Powered Down

Some computers do not send a reset signal to the parallel port that is strong enough to reset the scanner. If this happens, unplug the scanner from the electrical outlet, reboot your computer, and plug the scanner back into the electrical outlet.

Pictures Are Streaky

Sometimes pictures that appear streaky on the computer monitor will print fine on an inkjet printer.

If your printed pictures have streaks that run down the image in the same direction that the picture traveled through the scanner, try cleaning the scanner glass. Refer to the section called Maintenance for information about cleaning the scanner glass.

If streaks still appear after you have cleaned the scanner glass, run the Diagnostics software and recalibrate the scanner. Information about recalibrating your scanner is in the section called Testing and Calibrating Your Scanner.

Can I Use a Parallel Switch Box to Hook Up the Scanner?

You can use a parallel switch box with the Snapshot Photo Scanner, but only use a switch box that switches all 25 signals in the parallel cable.

Damaged White Reference Strip


Damaged White Reference Strip

The 100 lines are normally scanned using the scanner's internal white reference strip (located under the scanner cover). If this white strip is damaged you will have to use a different white reference. The plastic protective carrier that is included with the Snapshot Photo Scanner has a white backing which you can use to calibrate the scanner. The scanner will scan and average 100 lines of the white part of the plastic carrier.

If the white strip on your scanner is damaged, follow these steps for optimum calibration results:

1.	Open the scanner cover.

2.	Clean the white side of the plastic carrier.

3.	Clean the scanner window to remove dust and dirt.

4.	Place the plastic carrier with the white side face down on the scanner window.

5.	Close the scanner cover and keep it closed during the calibration.

6.	Click on the Calibrate button in the Diagnostics software window.

The plastic carrier moves about one-half inch through the scanner and stops when the scanner has finished reading 100 lines.

7.	Open the scanner cover.

8.	Remove the plastic carrier.

9.	Close the scanner cover.
