increased, the timing is delayed.
When the adjustment value is changed by 1, the timing is changed
When the adjustment value is changed by 1, the timing is changed
by about 10ms. The setting range is -490 - +490ms.

Note on "Large size" and "Small size"
Small size: The paper length in the transport direction is shorter than the LT size (216mm).
Large size: The paper length in the transport direction is longer than the LT size (216mm).
* The adjustment unit is a distance of 0.1mm unit.
* The smaller the set value of the warp amount for each of the specified items is, the smaller the warp is. The greater the set value is, the

greater the warp is.
* DSPF REGI1 is the registration amount adjustment in the paper feed side. DSPF REGI2 is the registration amount adjustment at just before
scanning.
