Subject: Scanning Application Force Quits on Mac OS 10.4
This bulletin was created to inform you of an error that may occur when opening a TWAINcompliant scanning application on a Macintosh computer running OS 10.4.
Description of Problem:
When launching a Twain-compliant scanning application after deleting your Epson Scan driver
with an Epson Scan uninstaller not compatible with your scanner model, the application will
force quit during start-up. For example, using a Perfection 4490 driver uninstaller to delete a
Perfection 3490 driver will cause your scanning application to suddenly close during start-up.
This issue affects the following TWAIN-compliant applications:

Assistant force quits
Copy Utility Force quits during start-up
Photo Impression Force quits during start-up
Photoshop Elements Force quits during start-up
Photoshop Force quits during start-up
Photoshop CS2 Force quits during start-up
This issue can also occur under the following conditions:
1) Dragging the Epson Scan folder (located in the Applications folder) to the Trash can
2) Upgrading your scanner and using the Epson Scan driver from the new scanner to
delete the driver from the older scanner, and then installing the new driver
Operating Systems Effected:
Mac OS 10.4 to 10.4.9
Affected Epson Scan Driver Versions:
2.70A or later

Correct Procedure for Deleting Epson Scan Driver:
! Use the driver specifically written for your scanner model to uninstall the Epson Scan
driver.
! If you have more than one Epson scanner model on your computer, use the driver
specifically written for each scanner to uninstall its respective device driver.
! If upgrading from a Power PC-based Epson Scan driver to a Universal Binary driver,
first delete the Power PC driver using only the Power PC driver for your scanner model.
Then install the Universal Binary driver.
If the above procedure does not resolve the problem, then manually verify that the Epson
Scan files and folders, listed below, have been deleted.
! EPSON Scan (in Applications Folder)
! EPSON*********.ds (****** = scanner model)---located in the Library / Image Capture /
TWAIN Data Sources folder

implementation of DIGITAL ICE Technology. It provides such information as: how DIGITAL ICE works, why it
takes longer to scan with DIGITAL ICE, and the functional limitations of DIGITAL ICE and the Epson Scan
software. You will also find inform at ion for the LaserSoft® Imaging Inc. SilverFast® Ai 6 scanner

Science Fiction (For more information on DIGITAL ICE visit their web site at: www.asf.com)
The award-winning DIGITAL ICE Technology automatically removes surface defects, such as dust and
scratches, from a scanned image. DIGITAL ICE technology differentiates itself from software-only solutions
because it does not soften, blur or otherwise alter any underlying details or composition of the original image.
Instead, the patented DIGITAL ICE technology works from within the scanner, during the scanning process, to
provide users with a clear, authentic base image that improves the original image.
Description of DIGITAL ICE Technology (taken from the Perfection 4870 Quick Guide)
The Perfection 4870 scanner includes DIGITAL ICE Technology for both photo prints and film. The DIGITAL
ICE Technology is built into the hardware of the Perfection 4870 Series scanner and works with the DIGITAL
ICE software built into the Epson Scan driver. T he com b inat ion of hardware and software lets you scan,
correct, and restore your photos in one easy step, without any compromise to im age quality. Note:
ICE Hardware and Software are both required for the DIGITAL ICE Technology to function.
DIGITAL
The DIGITAL ICE function can be divided into two types according to what you are scanning. DIGITAL ICE for
Photo Prints is used for photographs, and DIGITAL ICE for Film is used for positive films, color negative films
and monochrome negative films.
With DIGITAL ICE for Photo Prints, your scanner examines your photo for defects on the surface, such as
scratches, tears, cracks, and debr is. It does this by shining a second light source on your photo and storing
information about the shadows these defect s cr eate in a separate data space. It then uses this inf or m ation to
remove the defects from your scanned im age so you don’t have to remove them yourself.
DIGITAL ICE for Film uses a different method to automatically remove scratches, dust, and fingerprints from
your scanned image. During the typical scanning process, information is gathered using r ed, green, and blue
channels. With DIGITAL ICE for Film, an additional infrared channel collects the defect information for
correction. The results are truly amazing. Though it takes a bit longer to scan with DIGITAL ICE Technology,
the results will save you time. The majority of the painsta king work of removing scanned defect s is done for
you. Final touch-ups can still be done in your image-editing software such as Adobe® Photoshop® Elements
2.0 bundled with the scanner.
DIGITAL ICE for Photo Prints function outline
This scanner has two visible lamps for reflection. The lamps are placed symmetrically to provide the same
image when a scan is made twice. One of the propert ies of visible light is that it reflects ir regularly when it
radiates a flaw or debris. For this reason, t he im ages obtained with lamps A and B will have an inconsistent
area if there is a flaw or debris. This function determines the inconsistent area as a flaw or debris and then
automatically removes the unwanted defect.

DIGITAL ICE for Photo Prints function sequence
1. Scanner lights up lamp A and scans the imag e.
2. Scanner lights up lamp B and scans the imag e.
3. Software superimposes the images obt ained from each scan and determines the inconsistent area as a flaw
or debris.
4. Software then removes or fixes the inconsistent area(s) detected in step 3 and produces an image with
minimal defects.
DIGITAL ICE for Film function outline
DIGITAL ICE for Film uses infrared light for its process. Longer in wavelength than visible light, infrared light
has, as one of its properties, t he ability to scan film media transparently. Hence, when a f ilm im age with dust
and/or flaws is scanned using an infrared light, the infrared light is blocked at those points where dust and/or
flaws appear, thereby providing an image with only highly visible dust and/or the f laws. By superimposing the
images scanned with infrared light and visible light , it detects the dust and/or flaws on the document and
automatically removes them using the interpolat ed and corrected image data near the dust and/or flaws in the
image.
DIGITAL ICE for Film function sequence
1. Scanner scans a visible-light image.
2. Scanner scans an infrared-lig ht im age.
3. Software superimposes the images obtained from each light and detects t he flaws and/or the foreign
matter.
4. Software then removes or fixes the flaws and/or foreign matter detect ed in st ep 3 and pr oduces an image
with minimal defects.
DIGITAL ICE processing speed
Scanner processing speeds with DIGITAL ICE are highly variable and depend upon a number of factors such
as:
Host processing system configuration
USB 1.1/2.0 or FireWire)
Photo or Film type scan settings

Number of detected defects
Here are some examples of scan times with and without DIGITAL ICE technology over a FireWire ® IEEE -
1394 connection.
