Screws on the back of Sigma D25
On unboxing you should release the screws on the back of the printer. There are 4 screws that are all from the same type, but you should only release two of them. It would be good to mark these screws or the others that you don't get the idea to release all 4 screws.
Thanks for your feedback of the unboxing video, I will share it with the Media team to improve the video in order to make the unboxing process easier.
