B2375dfw printer service manual wanted

I ordered a new set of exit rollers for a b2375dfw printer. I'm in the process of dismantling it so I can replace them. I've got most of the screws holding down the top part (scanner/dadf), but it feels like there's one more under the operator panel. No idea how to remove it, and the clips under the operator panel are not budging.

Is there a service manual available for it? I followed tutorial videos on Youtube to remove the side panels and fuser, but they don't go any further than that.
