After nearly six years of very sterling service, I am having a problem with
my Epson Perfection 1640SU scanner. The scanner will still "Scan to Copy"
using Epson's Smart Problem but any function requiring the use of Twain
bombs out.



When using Scan to File, Twain opens and does a pre scan, and the pre
scanned document shows in the Twain preview panel, but when I press the
"Scan" button, I get the message "File.exe has a problem and needs to close.



A similar problem is experienced when trying to scan images using Paper Port
and Microsoft Photo Draw



My system is on Windows XP and I am using Epson Twain 5.53, which gave no
problems previously.



I have uninstalled reinstalled both the Scanner Twain and Epson Smart Panel,
several times without result. Any advice would be greatly appreciated.

Uninstall the TWAIN software.
Delete the files in %SystemRoot%\Twain_32\Scanner_Name\
%SystemRoot% is usually C:\Windows\
Reboot

Install the Latest software from Epson.

The latest is TWAIN Driver v5.71A (Rev. F)
 
Thanks for your response, however, I tried your suggestion, but the problem
is still persisting. I also tried restoring Windows to a date when I knew
that the scanner was working, but again no improvment.

I would welcome any further advice.

I have had many issues with Epson installers and uninstallers
for Windows. A few suggestions for what they're worth:


1. For Epson scanners:

Dig down in the Advanced control menus for
a button to Reset the scan driver to default values.
I've seen crazy scan problems solved by that.
Lord knows what it's trying to remember...

Eg., on the 4990, select Professional Mode, then
click Configuration, then the Other tab in the Config
dialog and then the button "Reset All."

Failing that, for Epson scanners or printers:

2a. Uninstall all Epson scanners and printers
using the regular Windows uninstall tools
(ie. from Control Panel, Add/Remove Programs.)

2b. Delete the EPSON subsection of the registry
You will need to use regedt32, not regedit, and
you will need to fiddle with permissions within
regedt32 just to be able to kill the EPSON key.
The key you need to kill is

HKEY_LOCAL_MACHINE\SOFTWARE\EPSON

3. Reinstall all Epson scanners and printers
with fresh downloads from Epson's website.

Note that USB enumeration and discovery must
happen at exactly the right point in the process.
In general the driver is installed BEFORE connecting
and powering up the peripheral (ie the scanner or
printer in question.)

Use this information at your own risk, particularly
items 2a and 2b.

Have you added or changed anything on the USB bus ? You might try a
different port or cable, dedicated.
 
My 1640SU worked fine for a couple of years and suddenly started
failing. I found that after I created a new userid I again was able to
use it as before under that new ID. I eventually rebuilt my XP system
and then everything worked fine under my normal ID. Using the an
alternate ID kept me going until I had time to rebuild.
