4.1.2 Respective Correction Data
(1) The shading correction data, sensitivity data, format data and speed
correction data are stored in the FLASH memory on the image
processing board (IMG17B), copied onto the SDRAM when the power
of the machine is turned on, and further defined on the scanner board
(SCTxxx) for use in operation.
(2) For the correction data, the types(s) (denoted by
m
) shown in the table
below is created according to the IP type and reading mode.
