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

 Upgrading from an earlier version of DeskScan
 ---------------------------------------------
   The Setup program for DeskScan II version 2.1 automatically
   upgrades earlier versions of DeskScan software. 

   Version 2.1 includes an HP ScanJet driver for ASPI- and CAM-
   compatible SCSI cards.  This driver is for use ONLY with the
   HP ScanJet IIc, IIcx, IIp or 3p scanners.  It will not function
   correctly with the original ScanJet (HP9190A) or ScanJet Plus
   scanners.

   If you already have an ASPI or CAM SCSI card, the new driver
   provides the advantages of using one less interface card slot
   and using less expansion ROM memory space.

   When you upgrade to version 2.1, the existing DESKSCAN.INI file
   is saved as DESKSCAN.BAK.  If you have calibrated print paths
   that you want to save from the previous version of DeskScan,
   you can recover them from the DESKSCAN.BAK file (see the
   "DESKSCAN.INI file" section below for more information on
   recovering old calibration files).



 Changes that DeskScan II Setup makes to CONFIG.SYS
 --------------------------------------------------

   Setup will ask your permission before making any changes to
   this file.  Most people will benefit most from allowing Setup
   to make the changes that it suggests.
   
   If you are installing for the ScanJet Plus scanner, Setup adds
   the following device driver line:

      DEVICE=C:\DESKSCAN\SJDRIVER.SYS

   If you are installing on a system that uses the HP SCSI card
   (HP P/N C1753-66500 or C1752-66500) shipped with the ScanJet
   IIc and older IIp scanners, Setup adds the following device
   driver line:

      DEVICE=C:\DESKSCAN\SJII.SYS
   
   If you are installing on a system that uses the HP SCSI card
   (HP P/N C2502-66500 or C2503-66500) shipped with the ScanJet
   IIcx, 3p and newer IIp scanners, Setup adds the following
   device driver lines:

      DEVICE=C:\DESKSCAN\MINI400I.SYS
      DEVICE=C:\DESKSCAN\SJIIX.SYS

   If you are installing on a system that uses an ASPI- or CAM-
   compatible SCSI card (that is already installed in you
   computer), Setup adds the following device driver line:

      DEVICE=C:\DESKSCAN\SJIIX.SYS



 Changes that DeskScan II Setup makes to SYSTEM.INI
 --------------------------------------------------

   Setup will ask your permission before making any changes to
   this file.  Most people will benefit most from allowing Setup
   to make the changes that it suggests.
   
   If you are installing for the ScanJet Plus scanner, Setup will
   not add any lines to this file.

   If you are installing on a system that uses the HP SCSI card
   shipped with the ScanJet IIc and older IIp scanners, Setup adds
   a line in the [386Enh] section that is similar to the following
   line:

      EMMExclude=c800-cbff           ;HP DeskScan v2.1

   The actual values in this line will depend on the switch
   settings on the card.  The value of the switch settings can be
   seen at boot time when the scanner driver is loaded (look
   quickly, it goes by fast!).

   If you are installing on a system that uses the HP SCSI card
   shipped with the ScanJet IIcx, 3p and newer IIp scanners,
   Setup adds the following lines to the end of the [386Enh]
   section:

      device=C:\DESKSCAN\WIN400I.386
      device=C:\DESKSCAN\HPSCANR.386

   If you are installing on a system that uses an ASPI- or CAM-
   compatible SCSI card (that is already installed in you
   computer), Setup will not add any lines to this file.

   Note:  Setup will examine this file for old HP DeskScan 
   modifications that are not valid for the new installation.
   For example, Setup will remove references to WIN400I.386
   and HPSCANR.386 if you are installing for the HP ScanJet Plus
   scanner or the older HP SCSI card.
 
 
 The DESKSCAN.INI file
 ---------------------
 
   This is the DeskScan II "initialization" file.  It stores
   DeskScan's default settings and all the customization you do
   to DeskScan as you run the program.

   This file MUST reside in the DESKSCAN directory (or whatever
   the name of the directory is where you installed DeskScan II).
   
   This file is not intended for modification by any program
   other than DeskScan.  However, if you have created custom
   calibrations for your printers or applications in an earlier
   version of DeskScan, you can copy them to the new DESKSCAN.INI
   file.
 
   To do this, open the old version (DESKSCAN.BAK) and the new
   version (DESKSCAN.INI) in a plain-text editor.  Copy all the
   lines under the [Calibrations] section in the .BAK file under
   the [Calibrations] section in the .INI file.  Don't leave any
   blank lines after the [Calibrations] line.

   If you installed the new version of DeskScan II over the old
   version, all the calibration files will be available.  If you
   have installed DeskScan II into a new directory, you must copy
   all the file names called out under the [Calibrations] section
   from the old directory to the new.


 The HPDS21.INI file
 -------------------
   
   This file resides in the WINDOWS directory and is used so that
   the HP DeskScan II TWAIN data source can find the main 
   DeskScan II program file.  It maintains the directory name
   where you installed DeskScan II.

   If, for some reason, this file becomes corrupted (DeskScan II
   will tell you that this has happened through an error message),
   simply copy the original version of this file in the DESKSCAN
   directory to the WINDOWS directory.

   If you rename the DESKSCAN directory (or whatever the
   directory name is where you installed DeskScan II), run
   DeskScan II by double-clicking the icon in the DeskScan II
   Program Manager Group BEFORE trying to run DeskScan II through
   TWAIN.  This will allow DeskScan II to update the path in the
   HPDS21.INI file.



 Removing DeskScan II from your computer
 ---------------------------------------

   Read UNINSTAL.TXT in the DESKSCAN directory to find all the
   changes to your system made by the Setup program and how to
   remove them.



 Scanning for ColorSmart printer drivers
 ---------------------------------------

   DeskScan II includes a special calibration file to help you
   achieve better colors when printing to your color printer
   using a ColorSmart printer driver.  Select this calibration
   file from within the Printer Calibration section of the Custom
   Print Path dialog box.

   For best color matching, create a custom print path for your
   printer and select "ColorSmart" in the Printer Calibration
   combo box.
   
   If your printer is a 300 dpi device, we suggest that you enter
   "300" in the "Drawings and   Halftones" text box and "100" in
   the "Photos" text box.

   If you have a 600 dpi printer, we suggest that you enter "600"
   in the "Drawings and Halftones" text box and "150" in the
   "Photos" text box.  Remember to name and "Add" your new print
   path before leaving the dialog.
   
   For general information about how to create a custom Print
   Path for your printer that can be selected from the "Path"
   combo box on the DeskScan II front panel, please refer to
   chapter 2 in the DeskScan II User's Guide.



 Scaling images scanned with a transparency adapter
 --------------------------------------------------

   The HP ScanJet IIcx scanner supports scanning from a
   transparency adapter (the IIcx /T). 

   Under some circumstances while scaling an image, minor defects
   common to all CCD scanners may become more noticeable.
 
   If you are confronted with this problem, scan the image at 50,
   100, 150, 200, 300, 400, 600, or 800 dpi.  Then, transform the
   image to the desired resolution by "resampling" it with an
   image editor, such as Aldus PhotoStyler or Adobe PhotoShop.

   This will reduce or remove any CCD-related defects.



 DeskScan II and Windows/NT
 --------------------------

   DeskScan II version 2.1 is not currently supported under
   Windows/NT.  However, if you would like to try running 
   DeskScan II on your system with Windows/NT v3.1, please read
   the README.NT file on the DeskScan II distribution disk for
   information about how to install DeskScan II.

   Please call HP's Automated Support Access Program at
   1-800-333-1917 (or 1-208-344-4809), or your local support
   provider for the most current information about support for
   MS Windows/NT.

   You can also check the HP Peripherals forum on CompuServe or
   Internet to find the latest information.  
   
   At any CompuServe prompt type,

      "Go HPPER"

   To connect via the Internet, use either the alias,

      ftp-Boi.external.hp.com

   or the IP address, 192.6.71.2.  Login as 'anonymous'.  Use your
   Internet alias as the password (e.g. 'yahoo@lab.hp.com').



 DeskScan II and OS/2
 --------------------

   DeskScan II version 2.1 is not currently supported under OS/2. 
   Please call HP's Automated Support Access Program at
   1-800-333-1917 (or 1-208-344-4809), or your local support
   provider for the most current information.

   You can also check the HP Peripherals forum on CompuServe or 
   Internet to find the latest information.  
   
   At any CompuServe prompt type,

      "Go HPPER"

   To connect via the Internet, use either the alias,

      ftp-Boi.external.hp.com

   or the IP address, 192.6.71.2.  Login as 'anonymous'.  Use your
   Internet alias as the password (e.g. 'yahoo@lab.hp.com').



 Updating HPSCANER.DLL
 ---------------------

   When scanning via TWAIN from some applications, you may see the
   following message:

      "DeskScan II cannot start scanning.
      
       An out-of-date version of the file 'HPSCANER.DLL' is in use
       by another application.
       
       See README.TXT to learn how to correct this problem."

   If you see this message, the application that is calling
   DeskScan II is using an out-of-date version of a file called
   "HPSCANER.DLL".  The most appropriate version of this file for
   use with DeskScan II is found in the DESKSCAN directory.  The
   other application's version of this file must be updated before
   it can correctly use DeskScan II.

   To update the other application's version, first close both
   DeskScan II and the application (you may want to close all 
   open applications, just to be safe).  Then, look in the 
   application's directory for a file named "HPSCANER.DLL".
   Copy the up-to-date version of this file from the DESKSCAN
   directory into the application's directory.  Restart the
   application, and again try to "Acquire..." (run 
   DeskScan II via TWAIN).



 Making sure that TWAIN file versions are correct
 ------------------------------------------------

   It is important to the operation of DeskScan II that old
   versions of the DeskScan TWAIN data source files do not attempt
   to launch DeskScan II.

   The best way to do this is to delete old TWAIN data source
   files from your system, or move them into a safe place.

   To delete old versions, look into the WINDOWS\TWAIN directory.
   Delete any file named HPDSII.DS.

   To move the old files to a safe place, create a directory in
   the WINDOWS directory called TWAINOLD.  Copy any file named
   HPDSII.DS from the WINDOWS\TWAIN directory into
   WINDOWS\TWAINOLD.  Then delete the HPDSII.DS file from the
   WINDOWS\TWAIN directory.



 Controlling I/O space reserved for the SJIIX.SYS device driver
 --------------------------------------------------------------
 
   The HP ScanJet IIcx, 3p and newer IIp scanners use a newer SCSI
   interface card than does the HP ScanJet IIc and some older IIp
   scanners.  This newer card (HP P/N C1752-66500 [ISA] or 
   C1753-66500 [MCA]) automatically re-configures itself when
   another adapter card is put in the system.  The IIcx card uses
   one on the following I/O spaces for data transfer:

              280     330
              290     340
              300     348
              310     350

   If you want to choose the I/O space MINI400I.SYS uses, change
   the following line in your CONFIG.SYS file:

       DEVICE=C:\DESKSCAN\MINI400I.SYS

   to:

       DEVICE=C:\DESKSCAN\MINI400I.SYS /SETADDR=<I/O space>

   Where <I/O space> is one the above mentioned spaces.

   Most users will not want to make this change.  It is only
   necessary if one determines that the IIcx SCSI card is
   interfering with another adapter card in one's system.



 How to install DeskScan II with Norton Desktop
 ----------------------------------------------

   If you are running MS Windows using the Norton Desktop as the
   shell, you can install DeskScan II using the default directory,
   C:\DESKSCAN.  If you intend to use install to this default
   directory, you don't need to read the rest of this section.

   If you want to install to different directory, there is an
   incompatibility between DeskScan II Setup and the Norton
   Desktop.  To install to a directory other than the default you
   MUST first change the shell to PROGMAN.EXE before installing
   DeskScan II!

   How to change the shell:
 
     - From Windows, run NOTEPAD.EXE and open the SYSTEM.INI file
       (which is in the \WINDOWS directory).
     - In the [boot] section you will find a line that reads:
       shell=ndw.exe
     - Make a copy of this line and insert a ";" (semicolon) as the
       first character in one of the two lines.
     - Change the second copy to read:
       shell=progman.exe
     - Save the file, close NOTEPAD and restart Windows.

   After DeskScan II has been successfully installed, you can
   switch back to Norton Desktop by following these steps:

     - From Windows, run NOTEPAD.EXE and open the SYSTEM.INI file
       (which is in the \WINDOWS directory).
     - In the [boot] section, find the copy of the line with the
       semicolon that includes "shell=ndw.exe".  Remove the semi-
       colon.
     - Find the copy of the line you made that includes 
       "shell=progman.exe".
       Delete it.
     - Save the file, close NOTEPAD and restart Windows.
