I have (had) the exact same problem. To repair the paper rollers - the 2 plastic clips on the ends of the roller must be glued with an epoxy or crazy glue, along with a thin (strong) support material, like metal, a paper clip part or thin MDF board - to keep the end clips from breaking off. [ which in my case, caused an error light malfunction ].
Make sure the “L” facing clip is on the right.
Since [ 2019-2020 ] any replacements can NOT be ordered, the only option is to repair.
