At thistime, the pickup/feed roller and the separation roller serve to make sure that only one sheetof paper is moved forward; then, when the deck pickup sensor (PS101) detects the paper,the deck pickup roller releasing solenoid (SL101) turns on to move the pickup roller awayfrom the surface of the paper.The paper is moved to the registration roller of the host machine, and is made to arch forremoval of the skew.The registration roller controls the paper so that its leading edge will match the image onthe photosensitive drum.
