Command from COSY list rejected (EE 4080,3061)

I’m having problems with my injector.

It will move up and down to the seat with no problem but will throw an error and not move down to a sample vial.

Errors
“Command from COSY list rejected (EE 4080,3061)”
“Needle down failed (EE 4018, 16)”

Also if you do Needle up in Lab advisor (fine), but Needle down says it cant go any further (even if you do needle to seat it goes down fine).
