*1. Point 20 mm in front of secondary transfer.
*2. If the source of paper is the right deck and normal speed is used, the machine executes variable speed control
(speed used between normal speed and x1.8 speed) in relation to the timing at which the paper reaches the vertical
path 0 sensor (PS31) within interval B and C; this is to prevent interference between the trailing edge of the
preceding paper and the leading edge of the following paper otherwise occurring if the speed was fixed to x1.8
(because of the short distance from the point of pickup to the point of registration).
