Scanning high resolution images with or without DIGITAL ICE requires large amounts of hard disk space and

system memory. EPSON Scan will check your scan settings and compare them to your HDD space and

system memory before scanning. The maximum scan resolution for DIGITAL ICE for Film is 4800 dpi. The

following warning messages may appear if your PC does not have enough resources for your scan settings or

if you are trying to scan film above 4800 dpi with the DIGITAL ICE feature:

If you receive either of these messages while trying to scan high resolution images, try the remedies that the

6.25" x 6.25" at 4800dpi, (30,000 X 30,000 pixels) and the Image Type set to 48-bit Color (DIGITAL ICE on or

Mac Operating System). At 24-bit Color a 2.51GB file will be generated; at 16-bit Grayscale a 1.67GB file will

be produced and at 8-bit an 858.3MB file will be created (Note: TIFF Image file format must be used for large
