Abstract
A scanner device may create original data for one or more pages, and calculate a digest value utilizing the original data so as to create document data in an external storage device. If a remaining capacity in an internal storage device is not deficient, the scanner device may write a first type of target partial data in both of the internal storage device and the external storage device. If a second type of target partial data which is partial data of a target of a calculating process for calculating the digest value is stored in both of the internal storage device and the external storage device, the scanner device may perform a calculating process by utilizing the second type of target partial data being stored in the internal storage device.
