2-3 Performing Scanning
Scanning Pitch and Scanning Area
The methods for making the settings are different for plane scanning and rotary scanning.

Required Memory
[Required Memory] at the lower right of the [Settings for Scanning] dialog box is automatically updated when you change the
scanning area or scanning pitch. When this amount of memory exceeds the amount of free memory on the computer, perform-
ing scanning may result in extremely slow processing by the computer. We recommend making sure enough memory is in-
stalled in the computer when you are performing scans that use up large amounts of memory.
For reference:
Maximum memory use
(amount of memory used when scanning at maximum scanning area and minimum scanning pitch)
Plane scan : 1148 Mbyte (per surface)
Rotary scan : 1767 Mbyte
