drawer priints fine; manual feed reduces and moves image

MF743Cdw on a MacBook

I've tried printing from both Word 365 and Acrobat. My cousin is able to print my files with no problem, to either 8.5 x 11 or (as specified in the files) 8 x 5.5.

I can print fine to letter size from the drawer.

When I print to the 8 x 5.5 size on manual feed, the image is reduced by about 30% and only the top inch of it is on the paper.

thanks for helping!
