How do I fix TWAIN error? How do I fix Scan Gear error message cannot communicate with scanner?

try to disable the firewalls on your pc and antivirus

I had this problem too, and after a while just gave up on the uesless HP interface, and went to the simple but efficient Windows Fax and Scan program on the Start>Programs menu.

Hello,

The scanner function is not available when you are connected wireless, you must be connected via USB to your PC for the scanner to function correctly.

Unfortunately the 5510 is no longer supported by HP for OS X 10.5.x and up. On the Apple tech site, they actually redirect you to a page the HP upgrade page (read: buy a new one).

If anyone can think of any 3rd part software that works with this, please post!

Thanks!

I suggest using ISIS drivers instead of TWAIN. I have always had trouble with the twain drivers failing especially in paperport ive found the ISIS drivers to be much more stable.
If you do require TWAIN though best way to fix is un-install the software that the TWAIN driver came with and re-install it. Unfortunately thats the easiest solution.
If you want to try the isis drivers they should be on the cd that you used for the twain drivers just select isis instead.
Let me know if you need further assistance.

Once try to scan from the scanners and camera wizard to check the two way communication between the computer and the all-in-one.

1. Verify that the all-in-one product power is turned on and the printer cable is properly connected.
2. Click Start .
3. Click Programs .
4. Click Accessories .
5. Click Imaging .
6. From the Imaging application, click File , and then click Select Device .
7. Select the HP all-in-one device from the TWAIN source list.
8. Click File , and then Acquire Image . Imaging for Windows will scan from the all-in-one product using TWAIN software instead of the HP software.

If you are able to scan by performing the above steps then search for the file hpqscnvw.exe and try to scan from there.

If you are not able to scan even from the above steps, once refresh the USB cable and then try to scan again.

if you are able to scan from that file then try to scan from HP Director, if the issue persists then create a shortcut icon for that file and then try to scan else uninstall the software and reinstall.

Did you check HP's site?

HP Photosmart 2575 all in one...
Working in all areas... except scanner. Cannot scan document.. message states 'error communicating with device'

Hello,

 

I have seen your message stating that "Initialization failed - Unable to acquire TWAIN-compliant device" error is received when trying to connect USB-Parallel type to your Laptop.

 

Well,  Printer  Panasonic UF4100, recommends to use only " Printer/Scanner Interface as Bi-directional Parallel (IEEE1284) " means you need to use Parallel cable to connect Printer to the Computer/Notebook.  You may receive some communication error messages if you are using a  "PORT REPLICATOR CABLE"( USB TO PARALLEL connector).  The error message that you have received is related to the communication error. Futher, if you use same USB- Parallel cable for long time the Printer Hardware functionality might go bad, since Printer memory gets confused and will not read or detect the Cable , since it is not a cable to use  mentioned by Panasonic Manufacturer.

 

Let me tell you, general functionality of Printer like Printing would work even if you use USB-Parallel cable. But it is not a case with Scanner and Fax functionality.

 

Hence, I recommend you to use only Parallel cable to connect your Printer to the Laptops.

 

I hope that this will resolve the issue for you.

 

You can email me at [email protected] if you need further assistance.

 

Bye.

'Twain' only means 'Technology without an important name', as this is refering to your printer/scanner, i would suggest that you disconnect the printer and remove any driver from Add/Remove programmes. Re-install printer software/driver and re connect printer when prompted and if possible in a different usb port, if that's how it's connected. If the problem persists and the pc is unable to communicate with the printer the fault will lie with the hardware. Hope it's only a driver glitch.
