============================
If You Haven't Installed Yet
============================
The TypeReader Professional User's Guide recommends making 12mb of space 
available for TypeReader Professional's installation. This 
recommendation is based on the assumption that you are not using any 
disk compression software. Please note that if you are using disk 
compression software, you will need to make more space available. The 
amount of additional space required is dependent on the compression 
ratio of the compressed drive. We recommend that you have at least 20mb 
of compressed disk space available prior to installation.

The TypeReader Professional Installer displays a progress bar that shows 
how far (in percent of completion) the installation has progressed. This 
percentage is based upon the number of files copied. Because some of the 
files on the first two disks are rather large, the progress bar moves 
slowly during this sequence, and may appear to be frozen. This behavior 
is normal, and you will note by looking at your floppy drive that the 
installation program is accessing the disk.

===============================
Straighten Skewed Images Option
===============================
The Processing Option "Straighten Skewed Images" (found in the Settings 
menu) is not selected by default, although the other Processing Options 
are. The Straighten Skewed Images option is a very powerful tool for 
dealing with skewed images, and we recommend that you use this option, 
as needed. However, if your images are not skewed, this option will not 
help recognition and will increase the processing time. For this reason, 
we decided that this Processing Option should be deselected at initial 
install. Please note that the skew correction engine may adjust page margins
when straightening a skewed image. This may affect page margins in 
recognized text.

==========================

=======================
Scanner Troubleshooting
=======================

There are a number of possible reasons why TypeReader Professional might 
not be able to access your scanner. 

It is important to check the list of scanner manufacturers and models 
that TypeReader Professional directly supports. TypeReader Professional 
may support only one model from a scanner manufacturer that has several 
different models available. Refer to the TypeReader Professional User's 
Guide (Appendix A) for a list of scanners that are directly supported. 
If your model is not directly supported, TypeReader Professional can 
still work with your scanner if you have previously saved black and 
white (also known as "binary" or "line art") .TIF, .PCX or .DCX images. 
See "Using files from other scanning applications" in Chapter 7 of the 
TypeReader Professional User's Guide for full instructions.

You should verify that your scanner interface board is properly 
installed and the scanner is on-line before you launch TypeReader 
Professional. Certain TypeReader Professional supplementary scanner 
drivers check for the presence of an interface card when TypeReader 
Professional launches. Others check to see if the scanner is on-line. 
TypeReader Professional will be much slower in opening and displaying 
the Gallery if the scanner is turned off or not ready. 

There is also a chance that a memory address conflict or I/O address 
conflict exists. These conflicts stem from a variety of possible 
sources--video boards, SCSI devices, and network cards are the most 
common. If you have a network card installed in your PC, the default I/O 
address is typically set to 300 hex. Certain scanner interface cards 
also specify an I/O address of 300 hex. If you do have a conflict 
between the network card and the interface card, it is easier to change 
the address on your scanner interface board. This is usually 
accomplished by changing DIP switches or jumpers. Please consult your 
manufacturer's scanner manual on how to change the address settings.

A useful test of whether you have a memory address conflict is to use 
the EMMEXCLUDE command provided by Windows to block memory in the device 
range from being used to emulate expanded memory. As a temporary 
measure, insert the following line in the [386Enh] section of 
SYSTEM.INI:

	EMMExclude=A000-EFFF 

This will exclude the entire "device memory" range from use by Windows. 
If your scanner problems disappear after trying this, then you probably 
have an address conflict. You will then need to examine the addresses 
that your devices (including the scanner) are attempting to use.
 **NOTE**-- If you are using EMM386.SYS, or a third party memory manager 
(QEMM, for example), any include (I=) or exclude (X=) statements will 
take precedence over the EMMExclude statement.

If you just purchased your scanner, check to see if there is some kind 
of lock or shipping restraint. The scanner's carriage is usually held in 
place during shipment by some type of restraint, which must be removed 
before the unit is used. 

You should try to find an available 16-bit expansion slot in the host PC 
in which to install your scanner interface card. Some interface cards, 
even if they are "half-cards," are actually 16-bit cards. These cards 
will not operate properly if inserted into an 8-bit expansion slot.

================================
Temporary files & crash recovery
================================
TypeReader Professional temporarily stores the images it is processing 
in the directory TRPRO\TEMP. If for some reason, TypeReader Professional 
crashes, these images will be saved. If files exist in the TEMP 
subdirectory, you will be notified as you re-enter TypeReader 
Professional, and you will be asked if you want to recover these files. 
Please note that this is the only opportunity that you are given to 
recover these files. TypeReader Professional will automatically delete 
these files from the TEMP directory when you exit the program normally. 
Any located and recognized text will be saved except for any located and 
recognized text on the page that was active when TypeReader Professional 
crashed. 

==================================
Font Mapping & DOS Word Processors
==================================
By default, TypeReader will display and export the following fonts:
	Times New Roman for Serif fonts
	Arial for Sans Serif fonts
 	Courier New for Monospaced Fonts.
These are all TrueType fonts. If you are using a DOS Word Processor 
(such as WordPerfect 5.1) these fonts will be converted by your word 
processor from TrueType fonts to fonts that your word processor can 
display. Therefore, fonts in your DOS word processor may not directly 
match fonts in TypeReader. This may affect document characteristics such 
as how text is wrapped.

========================================
Using 16 & 24-bit Video Accelerator Boards
========================================
In our testing, we experienced some difficulty displaying recognized 
text at some zoom levels (Double Size and higher) when using the higher 
resolutions and/or a high number of colors with some 16 and 24-bit video 
accelerator boards. Two work-arounds would be to either view recognized 
text at a lower zoom level (actual size or 125%, for example) or to 
reduce the resolution and/or number of colors (256 or even 16, for 
example).

==============
Error Messages
==============

During the normal operation of TypeReader, you may receive a 
warning or an error message. The following section lists common
error messages you may encounter and suggests actions you can
take.

  

TR.INI -- SETSCAN.INI RELATED
=============================
"Your TRPRO.INI file does not contain a valid 'Base Directory=' entry.
 Please add the line 'Base Directory=<directory name>' to your TRPRO.INI
 file, where <directory name> is the directory where you installed
 TypeReader Professional."

"Your TRPRO.INI file in the Windows directory does not contain a
 'Dictionary Directory=' entry. TypeReader Professional cannot continue."

"The FORMATS directory is missing; some export file formats may not be
 available."

"The temporary directory in your TRPRO.INI is invalid.
 Using TRPRO\TEMP instead."

"Settings file is invalid."

    Any of these errors suggest that either TR did not properly complete
    the installation (due due a system or software-level incompatibility),
    or the TRPRO.INI file has been incorrectly edited., or perhaps corrupted

   You may do one of two things in order to repair this problem:

    > Attempt to re-install TR. If the cause of the problem is an
       incompatibility, the error may occur again -- in this case, use
       the following option:

    > Edit TRPRO.INI to correct the offending lines. TRPRO.INI is
       documented in Appendix E of the TypeReader Professional manual.


MEMORY RELATED PROBLEMS
=======================
"Not enough memory to [several] 
"Not enough System Resources"
"Out of memory."

    TR requires a MINIMUM of 4 megabytes of free RAM in order to operate
    correctly. If your computer has only 4 megabytes of RAM total, this
    is not enough, as Windows 3.1 will use approx. 2 megabytes of that
    RAM. Increase available memory (total/free memory is displayed in
    PROGRAM MANAGER:HELP:ABOUT PROGRAM MANAGER) to at 
    least 4 megabytes (4096 kilobytes). This can be done by closing applications,
   adding virtual  memory, or by adding physical RAM. Also, verify that you are 
   running only one program at a time in low memory situations. For optimum 
   performance 6-8mb of available RAM is preferred.


DISK ACCESS PROBLEMS
=====================
"Not enough disk space to save changes to the user dictionary."
"Disk is full."

    Increase available space on your hard drive, or insert an empty
    diskette to save files to. A typical TYPEREADER TIFF file will
    occupy approx. 40-50K of disk space.

"Out of file handles."
"No file handles available."

    In CONFIG.SYS, increase the number of file handles allocated. There
    will be a line which reads FILES=n, (where n is the number of file 
    handles, is the DOS default). Increase this value by 10 until the 
    error goes away. If the line is not there, insert it in the 
    CONFIG.SYS file.

"Drive not ready."
"Disk drive not ready."

    Is there a diskette inserted in the drive? If so, verify that it is
    formatted for DOS computers. If the error persists, try another
    diskette or drive.

"Unable to write image to image temporary file."
"Unable to create image temporary file."
"Unable to create temporary page file."
"Unable to [rename file, save file, create file, delete file]"

    Verify that all TypeReader directories exist, and relevant lines in 
    TRPRO.INI are correctrelated to this function exist. At times,
    disk compression software can cause problems for disk intensive 
    applications such as TypeReader Pro. If possible, try installing 
    TR Pro on an uncompressed drive  Is the file name you attempted 
    to save under a valid DOS (????????.???) file name? Also, drive 
    caching software may sometimes be a problem - try shutting off 
    WRITE-CACHING, or removing the cache altogether.


FILE ACCESS PROBLEMS
====================
"User dictionary file is too large."
"The user dictionary has invalid words in it."

    The user dictionary may be up to 256 Kb in size.
    Words in the user dictionary must be between 2 and 64 characters
    in length. They can contain only alphabetic and numeric characters
    with periods, apostrophes or hyphens.

"Unable to load *.DLL"
"Unable to load *.TRS"
"Unable to load GENERAL.US"

    These messages usually result from file corruption, but can be 
    memory-related. If not, a re-install of TR may be necessary to 
    solve these problems. 

"The file <filename> is read-only."
"File is Read Only."

    A file you tried to save is marked as read-only on the disk/diskette.
    Change the name of the file you are trying to save and repeat the
    process.

"End of file marker reached."

    TR found an End-Of-File marker within the file, before one was
    expected. The two most likely causes are that this is an unsupported
    image format, or the file is corrupt.

"File operation failed."

    While accessing the disk for writing, DOS returned an error. This error
    is somewhat ambiguous -- if the error persists, after checking the drive
    for enough space & proper operation (using CHKDSK /F, Norton Utilities,
    etc...), contact Technical Support for assistance.

"Invalid template format."
"Invalid template."

    The template file probably is corrupt. The template will need to be
    re-created.

"Resolution too small."

    The minimum image file resolution in TypeReader Pro is 200 x 100dpi 
    (standard fax resolution). Resolutions below 200 x 100 dpi are 
    unsupported.

"Non-TypeReader TIFF file."

    The most likely cause is a TIFF file which was originally created by
    TR Pro, but has since become corrupted or been stripped of TR's extended
    header information.  The file may be usable after being re-saved in
    another graphics application.

"Invalid TIFF file."
"Invalid image file format."
"Invalid image file."
"Unknown image file format."
"Invalid image structure."
"Unsupported image file format."
"Invalid image file compression."

    The image file you attempted to open is either corrupt, or of a
    format/compression method which TypeReader Pro does not support.

"Invalid file name."

    The file name you attempted to use is not a legal DOS filename,
    consisting of the characters a..z, 0..9, and certain symbols. A 
    valid DOS filename is of the form:"????????.???".

"Too many pages in document."

    TR supports a maximum of 999 pages in one document.

"No image in file."
"No image in page."

    The file or page being read did not have a valid image in it, or was
    corrupt.

"Cannot read settings file."
"Cannot read template file."

    The file in question is locked by another copy of TypeReader Pro, is
    corrupt,does not exist, or was created by a non-compatible version of 
    program.


SCANNER ACCESS PROBLEMS
=======================
"Unable to start the scanning process."
"Unknown driver error."
"Unable to load scanner driver."
"General error in scan/image drivers."
"Unable to find Scanner."
"Scanner has timed out."
"Scanner not ready."

    There are a number of possible reasons why TypeReader Pro 
    can not access your scanner, such as an I/O address conflict
    or a missing or incompatible scanner driver. Please see 
    "Appendix A" of the User's Guide or the "Scanner 
    Troubleshooting" section of this document for more
    information.
