halFILE for Windows Hardware/Software Issues


Using a Fujitsu ScanPartner 10 Scanner

1. KOFAX KF-920 version 1.11 or later
2. Adaptec 40 series controller (1542C)
3. APSI4DOS drivers
4. Install only KF-920 files during 920 install
5. Make sure PIXPERM.DLL and PIXDFLT.DLL is in \WINDOWS\SYSTEM directory only and not in \WINDOWS and their dates should be same as the FJSP.PCX in the \WINDOWS\PIXTRAN directory


Using a KF-9250 and the Panasonic SP-505 Scanner

There is a resistor on the KF-9250 identified as S17 or SP17 that should be removed if you are using this card with the above scanner. You should find this resistor as the farthest one from the socket. The symptoms of having the resistor in place are (1) the scanner will not scan or (2) the scanner scans but lines are displayed across the page or (3) the scanned image has speckles on it.


Kofax Software Engines

KOFAX Software Engines provide various software imaging features used by halFILE. The engines include:

Adrenaline 32-bit

An Adrenaline hardware or software engine and the halFILE 32-bit scan module is required to perform 32-bit scanning. Adrenaline drivers provide many image scanning and enhancement features such as deskew, despeckle, line removal, streak removal, bar code detection and more.

ImageControls

ImageControls is the software driver that provides image scanning features. It talks to KOFAX Hardware cards that drive the scanner. ImageControls must be installed for halFILE to work. Refer to the halFILE User Manual for installation notes.

KF-911

The KF-911 Software Engine is a royalty free image decompression and viewing engine that is automatically installed when ImageControls is installed. Refer to the halFILE User Manual for installation notes.

KF-920

The KF-920 Software Engine is an add-on engine that provides for SCSI-based scanning. With this software engine, which is sold individually for each PC that has a SCSI scanner, you do not need a KOFAX card to driver the scanner. We prefer using a KOFAX card because it seems to be more reliable. However, if you want to use a SCSI scanner you should use an Adaptec 1542C SCSI card or better if you want it to work. Refer to the halFILE User Manual for installation notes.

KF-940

The KF-940 Software Engine is an add-on engine that provides for image printing to a Windows-based PCL printer. This product, sold separately as a site license, is required for printing of images in halFILE. It works with a variety of printers but is most reliable with Hewlett-Packard models. To ensure fast print speed, increase the memory on the printer to 6MB. Refer to the halFILE User Manual for installation notes.


Kofax Hardware Engines

KOFAX hardware engines come in a variety of models depending on requirements for scanner support, speed, document size and resolution. These cards includes Adrenaline and KF-Series cards. Some scanners require a certain KOFAX card. High speed scanners require better KOFAX cards with more memory in order to run the scanner at its rated speed.

More memory is required on the card as you scan pages that are larger, scan at a higher resolution or use special features such as deskew. Computing Kofax Hardware Engine Memory Requirements To compute the approximate memory required use the following formula:

    600K + (Number of Images * Raw Image Size)

where

    Number of Images = # of prescans (set in Scanner Setup dialog)

                                    + 1

                                    + 1 (for image processing features including rotation, deskew, bar code, or annotation)

Raw Image Size

Example #1: Scanning letter pages at 200 dpi with 1 prescan plus deskew and rotation enabled. The amount of memory required on the KOFAX card is:

600K + ((1 + 1 + 1) * 467K)) = 2.0 MB

Example #2: Scanning B-size pages at 300 dpi with 2 prescans and no image processing. The amount of memory required on the KOFAX card is:

600K + ((2 + 1 + 0) * 2103K) = 6.9 MB

In general, 1 prescan is sufficient for scanners up to 35 pages per minute and 2 prescans are recommended for faster scanners. The maximum memory for the different KOFAX hardware controllers is:
 


Errors

VB Error 7 - Out of memory
If you are scanning, this is typically caused by inadequate memory on the KOFAX scan card to perform the task that you are asking it to do. We see this most often when deskew is enabled and pre-scan cache on the scanner settings is set to 0. A 2.5 MB or 3.0 MB KOFAX card does not have enough memory to deskew and cache the images. In this case, either turn off deskew (and deskew selected pages using the deskew icon) or turn pre-scan cache to 0.

You can also get this message by trying to scan a page that is too large using a resolution that is too high. For instance, scanning a B-sized document at 400 dpi. VB Error 52 - Bad file name or number This is usually caused when the scan operation tries to write a file and the drive or directory to write to does not exist. For instance, if you were scanning to a Novell Mapped drive/directory of K:\images and then logged in as a different user where the login script did not map in K:\images, when you scanned this error would occur.


Corrupted MS-Access Databases
(NOTE: halFILE databases stored in MS-Access are Access 2.5 databases.) If you get an error opening an Access Database, it may be the database is corrupted. Corruption typically occurs because the system crashed (power outage, Windows lockup) while the database was open. Within halFILE, there are some ways to repair certain corrupted databases. If the parameters database (PARAMTRS.MDB) is recognized as being corrupted, the system will automatically run repair on the database. If the basket database is corrupted, you must first determine which basket database is corrupted and then repair it. The basket database resides in the halFILE program directory and is named xxxddnnn.mdb where xxx is the application id, dd is the database id and nnn is a sequential counter. While the halFILE Image Database can be set up in Access, it is strongly recommended that an ODBC-compliant database such as Microsoft SQL Server or Sybase SQL Anywhere is used. If the halFILE Image Database is in access and becomes corrupted, the file to repair is xxxHFWdd.mdb where xxx is the application id and dd is the database id. This database can be repaired using Tools | Repair Database.

For other Access databases, you must either use VISDATA or Microsoft Access to repair the database.


Using VISDATA to repair corrupted Access databases
VISDATA is a program that can be used to design, view, repair and compact Microsoft Access databases. It can also view ODBC databases. VISDATA should have been installed as an icon in your halFILE group. If a database is corrupted, when you try to open it with VISDATA, you will get a `database is corrupted or not an Access database' message. To repair a corrupted Access database, perform the following steps:

1. Open a database other than the corrupted one using File-Open Database-MS Access.

2. Select Utility-Repair Database and select the corrupted database.

3. The database will be repair and, upon completion, you will be asked if you wish to open the repaired database. You can open it to make sure the repair went ok.


Compacting Access Databases

Like most database or index structures, Access databases require periodic compacting to rebuild the indexes and eliminate unnecessary or deleted space. It is also recommended that, after repairing a database, you compact it. Within halFILE, you can compact (or refresh) either a Basket database (xxxBSKT.MDB) or an image database (xxxHFWdd.MDB) using Tools-Refresh.

If you wish to compact another Access database you must use VISDATA or Microsoft Access. To compact an Access database using VISDATA:

1. Open any Access database using File-Open Database-MS Access.

2. Select Utility-Compact and select the database to compact.

3. Enter the database name to compact to. We suggest using the same file name but with a .CMP extension.

4. After the compact is complete, you must rename the compacted database to its original name from DOS or the Windows File Manager.
