    On a machine of this age the magenta developer may be depleted or the developer bearings may be leaking ... probably both.

    Reset? You can just forget that. =^..^=
    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

    Yuck...on a 2050, you'd be better off upgrading to a new one. That Machine
    came out around 2012. It isn't on the obsolete list, but probably will show up
    on the list November 2021, which means it will be DOA March of 2022.
    The developer unit is probably shot. Those things will leak past the v-ring
    seals, chew up the bearings and deplete the developer.
