Installing the PathScan Enabler IV
Software installation requirements
Your Pathscan Enabler IV comes with the image-editing software (Presto! ImageFolio), document
management software (Presto! PageManager), the Pathscan Enabler IV’s driver, QuickScan Setting and
LaserSoft SilverFast software. All of these software applications use approximately 160 megabytes of
hard disk space once installed onto your computer. To ensure room for installation, a minimum of 260 MB
of hard disk space is recommended. The USB Pathscan Enabler IV can only operate under the Microsoft
Windows Vista, 2000 Professional or XP operating system.
Hardware requirements
This Pathscan Enabler IV connects to your computer through USB, which supports hot Plug and Play. To
determine whether your computer is USB-capable, you must check the rear of your PC to locate a USB
jack that looks the same as the one pictured below.

Usage and maintenance
Operating the Pathscan Enabler IV
NOTE: Your Pathscan Enabler IV accepts to work with U.S. standard glass slides, 1.1mm thick, 1 x 3
in. in length and No. 1 coverslips. Some software programs have limitations as to the information they
can process. The capacity of the computer’s memory and free space on your hard drive can also limit
the physical size of the document that you scan.
There are different ways to operate the Pathscan Enabler IV:
1. From within an image-editing program that can acquire images from the Pathscan Enabler IV.
2. Using QuickScan feature by pressing QuickScan button. The QuickScan Setting program is
automatically installed as your Pathscan Enabler IV software.
3. Using SilverFast Launcher by pressing SilverFast button. This stand-alone program allows you
to perform advanced scanning features. For further information, please refer to SilverFast
User’s Manual.
An image-editing program has been bundled with your Pathscan Enabler IV on the included
Setup/Application CD-ROM. It will allow you to alter and correct any scanned images by using a variety
of filters, tools, and effects.
QuickScan is a program that allows you to conveniently scan images without the need to work directly
within any image-editing application (i.e. Presto! ImageFolio).

Using tissue slide holder
Insert the tissue slide glass into slots with emulsion (non-glossy) side down. There are arrows
and illustrations on the frame of each slot. Please follow illustrations to insert the tissue slide
glass.
ATTENTION: For correct scan results, always turn the slide with the top of the image
facing towards the back of the Pathscan Enabler IV (where power cord
and USB cord located) and keep emulsion (non-glossy) side down.
There is text to show the top and bottom of the tissue slide holder. With
the slide oriented correctly as described above, this text should be read
clearly (i.e. not backwards or up-side-down the slide).

QuickScan settings and preview windows features
Source: Tells the Pathscan Enabler IV the method you will use to scan images.
Tissue slide: Use this mode for scanning the tissue slide glass.
Scan mode: Tells the Pathscan Enabler IV the type of document you are scanning.
There are four (4) settings to choose from:
8-bit grayscale: Scans in 256 shades of gray, giving black and white
images.
16-bit grayscale: Scans in more than 65,000 shades of gray, improving
the realism of black and white images.
24-bit color: Scans in millions of colors for slide realism. Choose this
mode when scanning color slide. This is the best setting to select for
scanning the tissue slide glass.
48-bit color: Scans in billions of colors for professional imaging requiring
precise uniformity of color.
Resolution: Resolution is measured in dots per inch (dpi). The higher the resolution,
the more detailed the image, and the more memory and drive space the
image will use.
Filter: Filters will help improve your scans by allowing you to sharpen images
as well as remove excessive dots and distortion.
Average: Determines the medium depth of an image and averages
adjacent pixels to make images appear softer.
Blur: Lets you dull edges within an image, and decreases the contrast by
making dark edges lighter and light edges darker.
Blur more: Adds additional blurring.
Sharpen: Allows you to sharpen the edges within an image by making
the edges in an image more distinct. The sharpen filter also increases
contrast by making dark edges darker and surrounding light edges
lighter.
Sharpen more: Adds additional sharpening.

Unsharpen: Sharpens the edges in an image to remove the blurriness.
This is the best setting to select for scanning the tissue slide glass.
Brightness: This is the amount of light that is concentrated onto a document while it
is being scanned.
Contrast: Contrast adjusts the tonal range of an image by lowering mid-tone values
and increasing values for high and low tones.
Image Gamma: Used to adjust the colors in the image that will be
scanned into the computer. By adjusting the gamma, you can change the
tonal range of the selected color channel. Gamma values are primarily a
measure of the brightness of a color. The larger the gamma value, the
brighter the color becomes. The best setting to select for scanning the
tissue slide glass is an image gamma of 1.35.
NOTE: By changing the gamma value you are affecting the image data,
and influence how the image displays on your computer’s monitor and
printer.
Purpose: This menu includes FILE, PAGE MANAGER, PHOTOSHOP, IMAGE
FOLIO FUNCTIONS, which allows you to determine which software you
would like to use for the post-processing of the scanned tissue slide(s).
Auto density: Checking this box automatically adjusts the histogram to make the
scanned image clearer. It does this by increasing the difference between
color tones. This feature is available in tissue slide mode.
Color matching: This feature provides a particular color matching technique to maintain
color consistency between your output and the original image. This
feature is available in tissue slide mode only.
ATTENTION: Due to different color processing method, auto density feature and color
matching feature cannot be applied simultaneously. If auto density is
checked, then color matching feature will be in gray-out status and
unavailable. Likewise, if color matching is checked, then auto density
feature will be in gray-out status and unavailable.
Color
enhancement: This feature is to compensate negative’s underexposed green and blue
channels. If this feature is checked, pre-scan and scan time will
noticeably increase.
Auto crop: When this box is checked, the QuickScan program will identify the
dimensions of the image you scanned and crop around the edges. The
crop shape will be a square or rectangle and it will not trace the edges of
oddly-shaped images.
