We have been using an HP Scanjet 7450C scanner with the HP PrecisionScan Pro scanning software and Paperport. This combination of hardware and software worked very well for us allowing us high productivity, excellent control over the scanned images, and a very good and usable electronic filing system. All this changed immediately after installing Windows 7.
Under Windows 7 (both 32 and 64 bit versions), PrecisionScan Pro (using a TWAIN driver) will no longer "initialize" our Scanjet 7450C, even though the scanner is properly installed as shown by the Device manager. WIA applications such as VueScan work fine but none begin to be as useful as PrecisionScan Pro.
I tried a number of possible solutions and finally found a workaround that works but not very satisfactorily. Under a 32 bit (but not 64 bit) instance of virtual XP, PrecisionScan Pro will finally play nice with the scanner. The major downside results from Paperport (both versions 11 and 12) being very sluggish and prone to crashing in the virtual XP environment.
I have another idea I want to try. I am wondering if PrecisionScan Pro might be willing to behave if I use a SCSI connection instead of a USB connection. The existing USB connection functions perfectly because the scanner is properly shown in the Device Manager and WIA (not TWAIN) based apps work fine. Therefore, I am thinking the issue is with the HP PrecisionScan Pro TWAIN driver and how it communicates with the USB port under Windows 7. Maybe the HP TWAIN driver will behave better if it is only asked to talk to a SCSI connection.
Using a SCSI connection requires buying a new SCSI card, costing almost $200.00. I do not mind spending the money if I had some reasonable assurance it will work so I am looking for opinions. I can always return the card to Newegg less shipping but I would rather be fair and not risk cycling Newegg unless I have some reasonable assurance the SCSI card will resolve the problem.
It really would be nice to fix this problem and avoid all the inconvenience, crashes, and SSD overhead used by Virtual XP. It also would mean I can revert back to the 64 bit version of Windows 7 and take needed advantage of all of the new 4GB of memory we just purchased.
I have an HP ScanJet 4c scanner that still works great. It has a full-sized transparency adapter which makes it hard to replace. I need to install a driver for windows 7. where I can get one for this scanner?
My HP Scanjet 3500C won't function in W7. I have tried all drivers I could find and different OS settings. Is there a workaround? It worked well in Vista...
No drivers available thru HP, there nust be a generic or universal driver that must work.This scanner is like new, works fine with XP so I would really like to continue to use it.Ifthere is n way to do this I could use a suggestion of a compareable or better scanner to purchase.
I am having problems with my printer, it stopped printing altogether from Word documents and yet it prints pictures from the web but not the letters.I have installed another cable and the ink levels show half full, have also tried re-installing driver over old driver.
this scanjet was perfectly works on window xp , but after i switch over to window 7 my scanner stops working , is any one can find the solution for scanjet 2300c scanner in window7
