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. =^..^=

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.
