I presume you’re referring to the ‘motors jammed’ error and this is designed to detect when a part of a print is stuck in the tank. Generally, this gets thrown when the wiper or another motor doesn’t return to its home position in the amount of time the printer would expect. Excessive peel force can cause this as well but it tends to be fairly noticeable when the tank is struggling to peel.
I’ve seen this thrown by mistake a few times and if you checked the tank and didn’t seen anything, you should be good to go. I’d keep an eye on the print and if you notice this continuing, let me know so that I can get you in touch with our support team.
