- SUMMARY
- =======
-
- Windows NT version 3.1 supports the use of the Hewlett-Packard (HP)
- ScanJet IIc color scanner if you use it with the DeskScan II software
- supplied by Hewlett-Packard. In order to ensure that the scanner runs
- correctly under Windows NT, you must carefully observe the following:
-
- - The scanner must be connected and turned on before you start the
- computer.
-
- - The scanner must be unlocked.
-
- - The Microsoft-provided driver, HPSCAN16.SYS, must be loaded through a
- device= line in the CONFIG.NT file.
-
- - The HP-provided 25-pin terminator must be connected to the 25-pin
- Macintosh SCSI-out connection.
-
- - A supported SCSI Host Adapter must be used.
-
- - The cables must be SCSI I or SCSI II specification.
-
- - Install the most current version of DeskScan II software. The current
- version is 1.62.
-
- - The proprietary HP scanner interface card which ships with the scanner
- is not supported under Windows NT.
-
- MORE INFORMATION
- ================
-
- The following operational notes discuss each of the essential elements
- for correct operation of the HP ScanJet IIc. Troubleshooting tips and
- hints for more effective operation of the HP ScanJet IIc with Windows
- NT version 3.1 follow the operational notes.
-
- Operational Notes:
-
- 1. The scanner needs to be connected to the SCSI Host Adapter in the
- computer, turned on, and unlocked before you start the computer.
- Otherwise, the computer will not recognize the scanner. Unlike
- some versions of the Windows NT Beta, the scanner does not have to
- be installed, unlocked, and turned on when installing the released
- version of Windows NT.
-
- 2. Edit the CONFIG.NT file so that it contains a line which loads the
- HPSCAN16.SYS driver. Use a text editor, such as Notepad, to add
- the following line to the CONFIG.NT file:
-
- DEVICE=%SYSTEMROOT%\SYSTEM32\DRIVERS\HPSCAN16.SYS
-
- The CONFIG.NT file can be found in the SYSTEM32 subdirectory.
- Setup copies the files HPSCAN16.SYS, HPSCAN32.DLL, and SCSISCAN.SYS
- to the hard disk when you install Windows NT.
-
- 3. The Hewlett-Packard provided in-line terminator must be connected
- to the 25-pin Macintosh SCSI-out port. The scanner may not be
- recognized by the system or the DeskScan II software may fail to
- work if the SCSI bus is incorrectly terminated. Usually, a SCSI
- bus is terminated at both ends, but not in the middle. Therefore,
- if the scanner is the last device on the bus, the end of the bus
- will be at the 25-pin Macintosh SCSI-out port. Do not place an
- in-line terminator at the 50-pin SCSI-in connection. The scanner may
- not work properly if the HP provided terminator is replaced with a
- terminated cable or other SCSI device connected to the 25-pin SCSI-
- out port.
-
- 4. Microsoft has tested all of the SCSI Host Adapters listed in the
- Windows NT version 3.1 Hardware Compatibility List (HCL) with the
- HP ScanJet IIc. However, as stated in the HCL, not all of the SCSI
- Host Adapters listed will work correctly with the HP ScanJet IIc.
- The following SCSI Host Adapters on the HCL will not work correctly
- with the HP ScanJet IIc:
-
- Maynard 16-bit SCSI Adapter (ISA)
- Data Technology Corp. 3292 (EISA Adapter)
- Olivetti ESC-1 (EISA Adapter)
-
- The Maynard 16-bit and DTC 3292 SCSI Adapters are appropriately
- footnoted in the HCL as not working with scanners, but the HCL
- documentation does not mention that the Olivetti ESC-1 adapter will
- not work with the HP ScanJet IIc.
-
- 5. The HP ScanJet IIc is very sensitive to incorrect cabling. In
- order for the scanner to work, the cables must be of high quality
- and meet the SCSI I or SCSI II specification where appropriate
- (SCSI II Host Adapters require SCSI II cabling). You must ensure
- that all connections are firm, with all connector pins in solid
- contact. Shorter cables have a greater chance of success than
- longer cables. Be certain that the cables are in very good
- condition.
-
- 6. Use the most current version of the HP DeskScan II software.
- Presently, the most current version is 1.62. Versions earlier than
- 1.61 may not function properly under Windows NT.
-
- 7. Do not attempt to use the proprietary HP-provided scanner interface
- card with Windows NT. The supported SCSI Host Adapter takes the place
- of this card. However, HP has developed a driver that allows you to
- use the scanner with a SCSI adapter in the MS-DOS and Windows 3.0 or
- 3.1 environments. The name of this driver is SJIIIx.SYS and it is
- available by calling HP or from the HP forum on CompuServe.
-
- Troubleshooting Hints and Tips:
-
- If the scanner does not function or you get error messages from the
- DeskScan II software advising you that the scanner cannot be found,
- then try the following steps:
-
- WARNING: Using Registry Editor incorrectly can cause serious, system-
- wide problems that may require you to reinstall Windows NT to correct
- them. Microsoft cannot guarantee that any problems resulting from the
- use of Registry Editor can be solved. Use this tool at your own risk.
-
- 1. To check if Windows NT has recognized the scanner hardware, start
- the Registry Editor (REGEDT32.EXE) and choose the HKEY_LOCAL_MACHINE
- key. Select the following subkey
-
- \HARDWARE\DEVICEMAP\Ssci\Scsi Port 0\Scsi Bus 0\Target Idx
- \logical Unit Id 0
-
- where x represents the SCSI ID number for the scanning device.
- Examine the entry at the SCSI ID number of the scanner. This
- entry should have a value of HP C1750 A.
-
- 2. In the Control Panel window, choose Devices to see if the 32-bit
- driver SCSISCAN.SYS was started. If it has not started, attempt to
- start it by choosing the Start button. Do not attempt to change the
- method by which it starts by using the Startup button. The default
- setting in the Startup dialog box is System. If you try to change this
- setting to Boot or some other setting, you may lock your Windows NT
- installation. If this happens, you will have to disconnect the
- scanner, start MS-DOS, and disable HPSCAN16.SYS in the CONFIG.NT
- before returning to Windows NT.
-
- 3. If HPSCAN16.SYS is loaded as a device driver in the CONFIG.NT file,
- but you do not have the HP ScanJet IIc connected to the SCSI Host
- Adapter, then your Windows NT will hang when started. The computer
- will need to be restarted. To recover, either turn the machine off
- and reconnect the scanner, or use the "dual boot" functionality of
- Windows NT by starting the MS-DOS environment and editing the
- CONFIG.NT to disable the HPSCAN16.SYS device line.
-
- 4. The DeskScan II software installation program will create a group
- called Scanner in the Program Manager. In this group, you will see an
- icon of a scanner with the icon title of DeskScan II. You may also see
- icons titled Scanner Test and SCSI Addresses, however, these two
- applications are not compatible with Windows NT. No resolution or
- workaround to this problem exists at this time.
-
- 5. Be sure that the SCSI ID number set for the scanner does not
- conflict with the SCSI ID number for any other device on the SCSI bus.
- SCSI addresses 0 through 7 are displayed on a small, circular SCSI
- address indicator located between the 50-pin SCSI-in and the 25-pin
- Macintosh SCSI-out ports at the back of the scanner. In the middle of
- the indicator dial is a small, narrow slot which can be turned with a
- tiny flat-bladed screwdriver. Once you change the SCSI ID to a
- non-conflicting SCSI address, the new SCSI ID will be recognized at
- system startup and will be written into the Windows NT Registry.
-
- 6. To determine whether the HP ScanJet is locked or unlocked, look for
- a rectangular opening at the back of the scanner just above the 50-pin
- SCSI port. If there is a half-height black plastic block in the
- opening, then the scanner is unlocked. To lock the scanner, you must
- press down firmly on the plastic block. When the block is in the
- depressed position, a black bar will appear in the rectangular
- opening. To unlock the scanner, push the horizontal black bar back up
- to the top of the rectangular opening.
