1) It is very important that your IEEE 1394 host controller (FIrewire Card) uses a Texas Instruments chipset.  This can be confirmed by opening the Windows Device Manager.  Under the heading of IEEE 1394 host controllers you should see the entry "Texas Instruments 1394 OHCI Compliant Host Controller".  We recommend this firewire card https://www.unibrain.com/products/fireboard-blue-e-1394a-ohci-pci-express-adapter/

 

2) The recommended firewire card is configured for a PCIe x1 connector and it would seem logical to insert this card in an x1 PCIe slot.  However, frequently PCIe x1 slots are not connected directly to the microprocessor but rather connected through an auxiliary chip.  This can result in lower performance.  It is our overwhelming experience that x16 PCIe slots are typically connected directly to the microprocessor and perform better eliminating the reported issue.  We strongly suggest that the firewire card be inserted into a PCIe x16 slot.

 

3) Please check the computer BIOS settings.  Look for "C" states, "S"

states, and deep sleep states.  Disable these.

 

4) There is a utility program filename PxLProcessorIdleDisable.exe located at C:\Program Files (x86)\PowerScan 1000\Tools\FW Camera.  Double click this file to run it.  This takes a split second to run.  A command window will appear momentarily and then close. This changes a setting ensuring that firewire communications maintain maximum performance.

 

5) It may also be helpful to update the firmware of the camera.  This can be found in the following location after software installation.  C:\Program Files (x86)\PowerScan 1000\Tools\FW Camera\Firmware Update\FlashUpdate.exe

 

6) Make sure these 2 paths are in the exception list of the antivirus.

C:\Program Files (x86)\PowerScan 3000

C:\ProgramData\PowerScan 3000

7. At e-ImageData, we are proud to offer our loyal customers a fantastic upgrade opportunity to enjoy a new 500 series scanner that offers USB 3.1 capabilities and much more, at an amazing low price. In addition to the benefits of a brand new model, it is important to upgrade your FireWire model as it will be coming to end of life by December 2023 in conjunction with Windows 10 being phased out by the new Windows 11. This means e-ImageData will no longer be able to support FireWire models and your ScanPro will not perform at its best.
