This SP can be adjusted to correct reading of the paper length. The input from
SP6962-1 (paper length) and SP6962-021 (paper skew) are used together. After
two sheets of different length have passed, the amount of skew and offset are
calculated then corrected using this equation:
Y = aX + b
where:
X: Actual paper length
Y: Paper length read by machine (SP6962-1)
a: Skew correction (SP6962-21)
b: Offset correction (SP6962-22)
