User UWE solved this same problem for me on my 1541s. If the walking foot is set too high - so there is no pressure on it - the presser bar/foot doesn't move. On my machine, it's easy to misadjust the height of the walking foot so that it never presses on the material.

UWE - Genius! That solved it. Looks like my walking foot was set too high. No pressure on the walking foot, therefore no presser foot motion. I didn't previously understand what "activated" the presser foot. Now, I get it. As for the step height adjustment, it seems to be a standard thing for the 1541. Well covered in the docs. But that wasn't the source of the problem. The second set screw I messed with allows you to adjust the height of the presser foot. Manual instructs that the foot should be 9mm above the dogs, which is the amount it gets raised by the lift mechanism. You would only need to adjust the height if you have a foot with a non-standard height - since this is fixed by the location of the set screw hole on the presser foot. Here are some photos of the adjustments in question on the Juki 1541s. Note that these had nothing to do with the problem I was having. But useful to know where they are.

Hi. I appreciate your post. I'm having exactly the same problem with a Juki 1541s. Trying to solve it. Please share if you find a fix. I will do the same. Thanks, Sean Here's my post:

Hi, I could really use some help troubleshooting this problem. I have a very lightly used Juki 1541s. Has been a great machine up to now, but I made some standard adjustments to change the presser-foot height to handle a big stack of material. Also changed the walking feet to handle some cording. Then I went back to what I thought were standard settings and adjustments and the walking foot / presser foot combination. No idea what I did wrong, but now my presser foot bar doesn't move - at all. It's just stone dead, even if I remove the feet altogether. Rest of machine seems to be working normally. Not jammed. Clutch has not been tripped, but somewhere, something is preventing the presser bar from moving. I can't find any reference to this problem. I don't see it in the service manual, although I do see instructions for adjusting the presser foot height and have been through the steps outlined in the service manual, here: https://drive.google.com/file/d/1ix3CVBN8mJUaqVO8IyqAgUSQIAY3h6EZ/view?usp=sharing I have checked and played with various positions of both the step height adjustment nut and the presser bar height adjustment set screw. Still nothing. I suspect a loose or broken linkage of some kind, but can't figure it out. Thank you, in advance, for any insight. Because of this, machine is unusable. Does not advance material, thread binds and breaks after a few stitches. Here's what my machine is doing. Note zero motion in the presser bar (one on the far left): Here's another YouTube video of same model machine showing normal operation. Notice the distinct up-and-down movement of the presser foot, as it holds then releases the material between stitches.
