MX532 will not load photo paper

[antics]

My MX532 prints fine on    plain paper, but when I load a sheet of glossy photo paper, I get this error: Load paper and press OK. I've fiddled and researched, tried without plain paper below (ie just 1 sheet of photo paper), or on    top of several sheets of plain paper, but exactly the same error results no matter what. Help!

MacOS 12.7.4

Update: I was finally able to "get" a photo printed this way: when the printer began trying to load paper, I pushed the photo paper in, very lightly. I could hear clicks and finally it grabbed the paper and printed properly. I consider this just a workaround and not reliable though.
