The fusing roller's speed is slightly higher than the drum speed. The speed of the copy paper transport will slightly increase after the leading edge of the copy paper enters the fusing unit. To compensate for this, the speed of the original feed motor is corrected from the leading edge to 183 mm (A252 copier only). Adjust the paper registration for the rear original feed (A252 only). If the setting of SP#-74 is 1, this setting is used for the paper registration for the front original feed as well as the rear original feed.
