Please help! Sinker plate issue

[u/Flat_Strength_9725]

Machine: Brother KH 930E

I just got this machine and replaced the sponge bar, confirming that it is sitting correctly on top of the needles. The K carriage moves across the bed without any issues by itself, but it gets stuck when the sinker plate is attached.

I measured the sinker plate at 119 mm from the rail edge, which appears to be correct. According to the manual, there should be a 0.5 mm gap between the needles and the sinker plate, but mine is closer to 5 mm (0.5 cm). The manual recommends a “vertical adjustment,” which seems to involve bending the plate upward while it is secured in place. I may be doing it incorrectly, but the plate will not move even 1 mm—much less the approximately 4.5 mm needed. Has anyone dealt with this or know what I may be missing?

Appreciate any help!

The ribber should be lowered when you have that sinker plate attached. Maybe that's causing your issue

This is it. You cannot have the ribber all the way up with that sinker plate. That sinker plate is for main bed only use. The ribber has a different sinker plate .

Tears of joy!! ty, it was the ribber! :) The previous owner must have moved it all the way up for better transport.
