does the machine power up ??
if u do not have power up, it's not a E400 feeder code !!!
Is your Feeder working ??
can u make a copy or a print ?
u need to provide what is functioning & what is not !!!!!!!!!!!
when did this code appear = after service/during service/ while printing ????
Never see a Error code displayed that way/ on the back end with five numbers
if for an E400
Power of printer/Re-seat the cable going from the ADF CONTROLLER to MEMORY PCB

If E400 is still present it has been found that replacing the ADF Controller or MEMORY PCB may be necessary.
