Hello @Rebecca_McDermott have a nice welcome to the community!
Besides the crafter notes Zanxx linked, there’re many other topics giving all the hints about calibration and reading registration marks. Please, give them a try before contacting support, as it may delay the solution when all the answers you need are here in the forum (unless there is a technnical problem, which is not that common).
Please, visit the Community Guidelines📚 and make a quick search before creating a new topic to check if your subject has already been covered, thank you and feel yourself at home!
