Does anyone know how
the copy speed is changed on the 4530 to 5530
since the firmware is the same, I was told that there is a jumper that can be removed to change the speed. Same for the km-2530,3530?

I always thought they used a faster motor, did you check the part numbers on the motors.

one wire comming off the pspcb on the 45s and its a 55

the wire needs to go from cn-4 pin 5 from the power source board to a wire harness. Im sorry but im not sure which harness. Ill ask the person who updated ours and get back with the answer. It dose work however in fact km netviewer even reconises it as a 55 instead of a 45.

Funny, that pin isn’t listed in the service manual. It goes 1,2,3,4,7,8,9,10, pins 5 & 6 must have gotten lost in the translation.
