Form3 "Tank Missing" message


I just received my Form3 today. Setup went somewhat smoothly. Connected to my WiFi network (took a number of tries), took 2 tries to update to the latest firmware (after an initial error message).

The issue that I’m having is both the Form3 and Preform show the “Tank Missing” message. I’ve reseated the tank multiple times. I’ve also rebooted. I’ve cleaned the contacts with a cotton swab and IPA. Nothing I’ve done fixes the issue. Naturally, I’m hesitant to proceed further. I submitted a support request.

Does anyone here have any experience/advice to share?


I’ll answer my own question. After more failed reseating attempts, I went back and watched the Form3 Tank Handling video. I had watched it before, but it’s been a while. The correct technique requires an extra little push toward the rear. That worked for me and my tank is now recognized.


David, I had the same problem when I first got mine, you need conviction to push it in.


Absolutely! But with a brand new Form3, it was a little hard to overcome my trepidation that I might break something. Now, I preparing to do my 1st test print.


Same thing happened to me. A little nudge to the back is all it took ;-).


Thanks so much for this tidbit. I was having the same issue. Was super nervous about pushing this tank but got the courage after reading your post. I’m back in business! :slight_smile:


I’m having trouble with one tank “tank missing”, all others work, just purchased another form 3 so I thought i would try it in that one, it worked but after the first firmware update it did not detect that same tank anymore. The issue has nothing to do with not seating properly, the tray is pushed all the way back. the other trays are detected a long way out. The contacts are clean on the machine and the tank.

Anyone else have this issue?


Having the same problem today. I am very sure the tank is in position. Multiple restarts, I have tried everything. Waiting for support. Ordered another tank as well.
