The issue commenced with 10.5.2
Here is the answer from Epson, and it works:
To get the Epson Scan scanner driver running on the Intel Core Duo mac, a
complete cleanout and reinstall may be required.
In this case we would recommend using the following steps to get a full
cleanout of all hidden files from earlier Epson Scan version(s) and a fresh
install:
UNINSTALL
Note: the files found will vary by OS and driver version. Not all files and
locations will be present. If one file cannot be found, just skip to the
next item. If an EPSON SCAN or EPSON SCANNER named file is found in an
adjacent location, you can trash it. Do not remove any other EPSON files.
1. Go into HD, APPLICATIONS, UTILITIES and open ACTIVITY MONITOR. Highlight
the EPSON SCANNER MONITOR process and click STOP or QUIT PROCESS to FORCE
QUIT the process. Close ACTIVITY MONITOR.
In HD, APPLICATIONS - move EPSON SCAN and EPSON SCANNER MONITOR to the
trash.
2a. In HD, LIBRARY, APPLICATION SUPPORT, EPSON - remove EPSON SCAN, if
present. Also check the contents of the Epson folder. Remove only files
inside it that are related to the scanner, for example EPSON USB SCANNER or
EPSON FW SCANNER BUNDLE.
2b. Check in HD, LIBRARY, APPLICATION SUPPORT. There may be other Epson
files. Any files to do with the Epson scanner name or Epson Scan you can
remove from here.
3. In HD, LIBRARY, APPLICATION SUPPORT, TWAIN*, TWAIN DATA SOURCES - remove
EPSON SCAN, if present, and any files bearing your scanner's name. (*The
Twain folder may not be present on all OS 10.4 Macs.)
4a. In HD, LIBRARY, IMAGE CAPTURE, TWAIN DATA SOURCES - remove any Epson
scanner-named ".ds" files, for example the bearing your scanner's name,
EPSON STYLUS or PERFECTION #### X.ds
4b. In HD, LIBRARY, IMAGE CAPTURE, DEVICES, remove EPSON SCANNER.DS, if
present
(This is a generic resident scanner driver. Once the Epson scanner software
is working properly it will not be needed, so it can be deleted.)
5. In HD, USERS, (YOUR USER NAME), LIBRARY, PREFERENCES - remove EPSON
(scanner name ####) PREFS, if present
6. In HD, USERS, (YOUR USER NAME), LIBRARY, PREFERENCES, EPSON - remove
EPSON SCAN and EPSON SCANNERMONITOR PREFS, if present
Once the above files have been moved to the trash, you do not need to empty
the trash. Simply restart your Mac. You are ready to reinstall.
DOWNLOAD
If you have not done so already, use the following steps to obtain the
download for the new Intel Core Duo driver:
1. Go to
http://support.epson.com
2. Select Scanners, then Epson Perfection Series, then your scanner model
name.
3. Under DRIVERS & DOWNLOADS select Macintosh.
4. Download only the driver marked for the Intel Core Duo system.
Installation instructions:
1. After download is complete, double click the icon that appears on your
desktop. This will create a disk image on your desktop.
2. Open the disk image.
3. Double-click the EPSON SCAN INSTALLER icon to begin the installation.
4. Enter password and follow prompts to install the driver. At the EASY
INSTALL option, use the up/down arrows and select CUSTOM Install. Check
ONLY your scanner model before clicking INSTALL.
5. After installation is complete, quit the installer and restart the Mac
before testing.
To test this driver, do the following:
1. Launch Epson Scan by going into your HARD DRIVE, APPLICATIONS, and EPSON
SCAN.
2. If prompted, select your scanner from the list of models and click OK.
3. In the FILE SAVE SETTINGS window, you can designate the location, name
and type of file the scans will be saved as.
-LOCATION defaults to HD/USERS/(YOUR USER NAME)/PICTURES. Click CHOOSE if
you wish to change this.
-PREFIX determines how the scan will be named. Type any name you like. You
can also designate a start number.
-FILE TYPE dicates what format the scans will be saved in. ie. .JPG, .TIFF,
.PDF, or .PICT)
-For example: if the prefix is "img", the start number is "1", and the
format is "JPG", the name of the file saved in
PICTURES will be "IMG001.JPG"
4. Click OK once settings are changed as desired.
5. The EPSON SCAN window will open and begin scanning in FULL AUTO MODE. In
FULL AUTO MODE the software makes all the decisions for you (as to what is
being scanned, where it is on the flatbed, etc). This is the easiest way to
scan.
6. If you want full control over the scanning process click PAUSE and
change FULL AUTO MODE to HOME MODE or PROFESSIONAL MODE. In the latter two
modes you can change your scan settings as desired. Click SCAN after you
have selected your settings. Click CLOSE once the EPSON SCAN is finished
scanning.
7. When scanning is complete, your images will be saved in the location
specified on FILE SAVE SETTINGS, with the prefix and in the format you set.
