Before Installing the Software 

To avoid potential conflicts during installation of the
OneScanner Dispatcher software, you must first restart your
computer with extensions turned off. 

While holding down the Shift key, choose Restart from the
Special menu and continue to hold the key down until you see
a message indicating that the extensions are off. 

When you restart your computer after you install the
OneScanner Dispatcher software, the extensions will turn on
again. 

New to Version 2.1:  Using Virtual Memory

Previous versions of OneScanner Dispatcher were not
compatible with virtual memory. With OneScanner Dispatcher
2.1, you can now turn on virtual memory. 

Duplicating the Apple Color OneScanner Plug-In Module

The Apple Color OneScanner plug-in module allows you to scan
images directly into applications that are compatible with
Adobe(TM) Photoshop plug-ins. Make a copy or an alias of the
original plug-in and move the copy or alias to the location
you want. The original plug-in must remain in the Plug-in
folder in the Apple Color OneScanner folder or you will not
be able to create new scans with the OneScanner Dispatcher
application.

Note: Plug-in filters shipped with Adobe Photoshop are
proprietary and will not work with the OneScanner Dispatcher
application.

Checking File Formats for Drag-and-Drop Applications

If you add your own drag-and-drop applications to the
OneScanner Dispatcher window, make sure the applications
support the file formats you use to save scanned images. For
example, if you scan an image and save it in JPEG format,
the application you add must be able to open a JPEG
document.

Opening EPS Images in PowerPoint or Canvas

You should be aware that the PowerPoint and Canvas
applications sometimes cannot open images saved in EPS
format using the OneScanner Dispatcher application. Try
saving images in another format, such as PICT or TIFF, or in
any other format supported by your graphics application. 

Auto-Straightening

The Straighten feature relies on well-defined,
high-contrast, rectangular edges on the scanned document, as
well as some image content, to determine the correct
rotation required to straighten the image. This function
also expects the scanned document to be located away from
the edges of the scan window. If you have a problem with the
auto-straighten feature, you may be able to resolve this
problem by adjusting the image or document's tone. Click the
Tone button to open the Tone dialog box, and adjust the
brightness and contrast to a darker setting for better
results.

If the document you're scanning lacks a discernible straight
edge on the image boundary, you may not get satisfactory
results when you scan with the Straighten option on. Align
the document carefully on the scanner glass, turn off the
Straighten option, and try the scan again.

Using the Select All Command To Put an Image Into an Archive

To save an image that you just scanned, you can use the
familiar Save (or Save As) commands. If you have an archive
window open, however, there is another simple way to put the
new image into the archive.

1. With the image in the active window, choose Select All
from the Edit menu.

2. Drag the selected image to the archive window and drop it
there.

3. In the dialog box that appears, type a name for the image
and click Save.

If you change your mind and want to cancel the selection,
choose None from the Edit menu.

Resolving Conflicts With Earlier Versions of TextBridge OCR
Software

If you've installed an earlier version of the TextBridge
software, the AVision scanner driver may be in conflict with
the new Apple scanner driver used by TextBridge. To resolve
the conflict, follow these steps:

1. Open the Extensions Manager.

2. Turn off the AVision scanner driver.

3. Restart your Macintosh.

When you want to use the AVision driver again, you can use
the Extensions Manager to turn it back on.

Using the Automatic Document Feeder

CHECKING THE GLASS: Before you attempt to scan from the
document tray, make sure that no documents have been left on
the scanner glass. The document feeder won't work if
originals are on the glass. 

CHECKING THE PAPER: If you have problems with the document
feeder (for example, two pages are fed in at once), the
originals you are using may be damp. Always use dry
originals, and keep them in a dry place. 

IMPORTANT Some Adobe Photoshop plug-in compatible
applications will not support multipage scans and will only
scan the first page of a multipage document. 

Using the Transparent Media Adapter

SCANNING TRANSPARENCIES: For better image quality when
scanning 8" x 11" overhead transparencies, it is recommended
that you use the flatbed, not the optional Transparent Media
Adapter. 

SCANNING REFLECTIVE ART: For better image quality when
scanning reflective art with the optional Transparent Media
Adapter attached, it is recommended that you place a sheet
of white paper over your artwork to reflect light back to
the scanner, or use the standard flatbed scanner cover. 

Using an Earlier Model of the Apple Color OneScanner

You can use an earlier model Apple scanner alongside your
new Apple Color OneScanner. To save, open, and edit scanned
images, you must use the original software that came with
the scanner. The power and features of the OneScanner
Dispatcher application are available only if you scan images
with your new Apple Color OneScanner.

If you've connected your new scanner and the original
scanner in a SCSI chain, you can use either scanner, but
only one scanner at a time.

Follow these guidelines:

1. Replace the original scanner driver with the new scanner
driver.

2. Turn off the scanner you don't want to use.

3. Turn on the scanner you want to use.

4. Restart your Macintosh.

5. Use the original software that came with the scanner to
open, save, and edit images you scan with the original
scanner. (Ofoto software, for example, came with some older
scanners.) Use the new OneScanner Dispatcher application for
images you create with the new scanner.

Tips and Troubleshooting

MEMORY ADJUSTMENTS: To increase the OneScanner Dispatcher's
performance, try increasing the amount of memory assigned to
the OneScanner Dispatcher application. For information about
changing application memory, see "Allocating Memory" in
Macintosh Guide (the onscreen help system).

INTERLACED GIF FILES: Some GIF files are interlaced and are
not supported by the OneScanner Dispatcher, causing images
to be distorted. 

JPEG COMPRESSION: JPEG does not support black and white or
halftone images. It is recommended that you save these types
of files in uncompressed TIFF or PICT format.

RESOLUTION REQUIREMENTS: The OneScanner Dispatcher
application requires a minimum monitor resolution of 640 x
480.

HARD DISK SPACE REQUIREMENTS: You need approximately three
times the image size in free hard disk space to be able to
open images. For example, if you scan an image that is 3 MB,
you need at least 9 MB of free hard disk space to open the
image.

COLORSYNC 2.1: ColorSync 2.1 is an Apple system extension
that makes colors consistent across various input and output
devices, such as scanners, printers, and monitors. Saving,
opening, and editing images may take a little more time with
ColorSync on. To maximize your scanner's speed, try turning
ColorSync off. See your user's guide for instructions. For
additional information about ColorSync and Apple Color
OneScanners, as it becomes available, see the Printers and
Imaging World Wide Web (WWW) site. The Web address is:	
http://product.info.apple.com/productinfo/datasheets/imindex.html

PRINTING TO LASERWRITER PRINTERS: To print to a LaserWriter,
click Scan and then choose the name of your LaserWriter from
the Destination menu.

FASTER SCANNING: For faster scan speeds, Apple recommends
that you use resolution settings of 75, 150, 300, 600, or
1200 dpi. 

METATOOLS KPT AND CONVOLVER: MetaTools Convolver bundled
with the Color OneScanner 1200/30 does not support grayscale
images. If you are using KPT or Convolver, increase the
amount of memory assigned to the OneScanner Dispatcher
application by at least 2 MB of random-access memory (RAM).

MULTISYNC DISPLAYS: When changing the display resolution
with an open image, you must close the image and reopen it
for the Tool palette to be positioned correctly.
