The chart below shows typical scan times for a 4" x 5" positive film image on an older PC.
High resolution scanning with or without DIGITAL ICE
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
messages suggest: reduce the scanning resolution/scale setting or decrease the selected area. Epson highly
recommends that scans with or without DIGITAL ICE should not exceed the industry standard of
30,000 X 30,000 maximum pixels or approximately 6.25" x 6.25" at 4800 dpi. With a scan size setting of
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
off), the Perfection 4870 Series scanner will generate a 5.02GB file (Note: this setting is not supported on any
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
