B. Controlling the feed speed
1. Outline The feed speed is controlled with the feed motor (M2) and torque limiter. The feed motor changes the feed speed according to the paper size but rotates at a constant speed and does not control the speed when feeding copies. The feed speed of the sorter is higher than the delivery speed of the copier. When one end of a sheet of copy is in the fixing unit of the copier and the other is between the feed rollers of the sorter at the same time, the feed roller rotating speed is reduced with the torque limiter.

Figure 2-303 2. Process speed Process speed is the speed of the copies from the time when they are received from the copier first until they are transferred fully into the sorter. This speed is the same as the process speed of the copier. 3. Pull-In/Delivery Speed The tern refers to the speed at which copy paper is moved from the copier's fixing assembly for delivery, and it varies between 380 and 570 mm/sec according to the size of paper. The following shows the relationship between typical paper sizes and feeding speeds.
Paper size B4, LGL A3*1, 11"x17" A4R, LTRR 4A, LTR Feed speed 540mm/sec 510mm/sec 470mm/sec 450mm/sec
*1 If stacking is not proper because of downward curling in staple sort mode, change the feeding speed. (See CHAPTER 5. Dipswitch function list)
