                  What happened?

                  The filament has been ejected to the front of the MMU unit, so that you can remove it.

                  This feature is handy in case you are using the Spooljoin function. A depleted filament might be too short to be removed from the back of the unit. By ejecting it to the front of the unit, you can easily grab it and discard it. 

                  How to proceed?

                  Remove and discard the ejected filament and press the button on the LCD screen.

                  If you accidentally triggered the eject function, push the ejected filament back into the MMU unit and make sure it isn't protruding from the short front PTFE tubes so that the selector doesn't jam later on.

                  I still had some of a roll left when I got the error. So I grabbed the end of the filament which had been ejected and it turned out. It was only 250 mm long since I was near the end of a role I changed roles and I pushed the new filament toward the MMU. However, I didn’t go into the proper hole. It went over the top so I got a pair of surgical thin tweezers and magnifying glasses and put it into the correct position. Then I restarted interestingly it went through a filament load procedure after which I pressed yes and then it continued. I’m learning all kinds of ways not to stop the job.

                  Hm. I unscrew one of the silver ends at the PTFE Tube in the Front. I am able to grab the filament. But it is stuck in the print head, because the print head decided to cool off after a while. How do I get the printhead to heat up again? Or what am I supposed to do? I would hate to lose this print. Again.

                  How I solved the Problem.

                  I replaced the empty Filament roll with a new one. And I pushed the new filament through the whole system short of the MMU. Then I unscrewed one of the silver things on the front PTFE tube. Now i pressed the button To continue. The printhead started to heat up again. At one point I was able to do a more or less cold pull on the remaining filament in the front. Now screw the silver thing back into its place.
                  When the filament in the front is removed and the printhead is heated the MMU should ask you to push the filament in to the MMU, so the MMU can load the filament.
                  Now the MMU should load the filament to the print head.
                  Follow the screen and happy printing.

                  > Remove and discard the ejected piece of filament

                  how do I do that ? unscrew those silver FESTO thingies ?!?
                  and why doesn't anything happen when I click the _Submit_ button above ?!?
                  well, maybe posting a comment works 😞

                  On my MK4 with MMU3, this is being triggered every 10 or so filament swaps and I'm not sure why. The spool has plenty of filament, and the light on the FINDA remains off, indicating the FINDA detects that filament is still present. I'm not able to verify the FINDA status in the Sensor Info menu because the "filament unload" screen takes over as soon as it happens.

                  Hi! FINDA status should be visible also in the footer area on the bottom of the screen. 
                  It seems, your FINDA probe might need to be re-calibrated - in case it falsely detects filament runouts during the print.

                  Also, check your slicing for unnecessary filament changes or
                  inspect the G-code for M600 commands.
