the RAM, download the data, thus eliminating the need for the following
adjustment.

controller; as such, you will have to make the appropriate adjustments if
you have replaced the reader controller or initialized the RAM.

generated for the following:
a. main scanning direction position adjustment (stream reading)
COPIER>ADJSUT>ADJ-XY>ADJ-Y-DF
