2) The AF stripper solenoid activates to lower the Shutter and Original feed arm comes down to hold
the original.
3) The Image scanner LED turns ON to make shading compensation.
4) With the press of the START key, the Read pulse motor activates to rotate the Original pickup
roller and Original stripper roller to feed the original.
5) The original, if fed in multi-layer, is stripped into one sheet by the Stripper roller and Original
