Seamless paper Coffee time

Hello again it’s kiku with dementia.
Please can you explain the 6x6” thing. Does this mean that I’ve got to cut my paper 6x6” and slot it into the paper feeder to get the correct size of the pattern ? And I’ve just found out that if I move the paper measure at the feed, then I don’t need to change the front panel on my Epsom 3150 . Is this correct? Sorry but you did say if I want any help😬🤪👵🏻🫶🏻Kiku
