Is your firmware up to date?

Have a look at the separator roller drive system. The newer units have a different type of one way clutch, I have had a few now that are all gummed up with thick black grease, cleaned it out and a bit of wd40 and off it goes. The easy way to test for it is to try to turn the sep roller by a finger tip in the direction of paper feed..it will be very tight if it is the problem.

the machine is on b4 firmware, i think i found the problem.

there was a semi - break on the brown wire connecting m27 feed moter
