MX532 won't print avery mailing labels

[antics]

Everything seems fine. Avery sheet loaded upside down. Printer says it has detected paper is aligned to one side. Well, the guide is as snug as it can be. So why won't it print? Error 2102

I registered for this forum, just so I could write to you and say thank you for this response! Seems pretty stupid on Avery's part, but you were 100% right. Peel off the Avery header, and it printed perfectly for me. You saved my wedding invite printing from being a very frustrating moment. Cheers!
