Feed roller may be driven depending on fitting position of gear joint plate of primary feed unit. If so, depending on timing of clutch being turned off, J1503/J1504(in case connected to main machine) and J3416/J3417 (in case connected to PF-780) may appear. Therefore, handle following when attaching primary feed unit or above phenomenon arises.

Check if there is a gap between the gear joint plate and frame.If there is a gap, handle in the following way. Loosen screws for gear joint plate and slide plate to fill gap with frame and fasten screws while aligning downward . If there is still a gap between gear joint plate and frame, remove gear joint plate and check if gear pin is inserted in hole on frame.
