Cannot Acquire Document; Cannot Change Resolution By Shrink To Half - Toshiba e-STUDIO 850 Series Manual

7 Troubleshooting

Cannot Acquire Document

Problem Description:
Cannot acquire a document using the TWAIN Driver.
Corrective Action:
The TWAIN Driver is carefully tested with several TWAIN-compliant applications. However,
some applications need settings to acquire a document from the device, and applications that
have not been tested cannot connect to the device. See the readme file about the required set-
tings in applications that have been tested. Also, you may be able to use an application that has
not been tested by enabling the TWAIN Driver's Native UI, or changing the Data Transfer Mode.
For more details about TWAIN settings on your application, see the user manual for your appli-
cation.
Saved as Single Page TIFF Files Even Though You Select
Multi Page TIFF Format
Problem Description:
Even thought you select to save the document as multi page TIFF format, the document was
saved as single page TIFF files.
Corrective Action:
The File Downloader cannot save the color and black/white mixed document as a multi page
TIFF file. In that case, the File Downloader saves the black and white document as single page
TIFF files, and color document as JPEG files. If you want to save the document as one file,
save it as a PDF file.
Cannot Open TIFF File Saved Using File Downloader
Problem Description:
Cannot open the TIFF file that has been saved using the File Downloader.
Corrective Action:
When you select TIFF format to save the color/grayscale document using the File Downloader,
the document will be saved as TIFF file with JPEG compression. If you open the file using an
application that does not support the TIFF file with JPEG compression, it cannot be opened. In
that case, save the document as a JPEG file or PDF file.

Cannot Change Resolution by Shrink To Half

Problem Description:
Even though you enable the Shrink to Half function, the resolution of an image that was acquired
is not changed.
Corrective Action:
The Shrink to Half function is available only for 600x600dpi documents that are stored in e-Filing
by copy and print operations. This function cannot reduce the resolution of an image that is
stored by scan and fax operation. If you want to change the resolution of the image, change the
resolution after opening the file using an application.
