PYE prv645 problem

i’ve just brought one and every time i put a blank recordable disk in it reads it then the tray opens again, i new to this and i’m probably just being a bit thick but i need some help

What sort of discs did you put in?

  1. +R or +RW
  2. -R or -RW?

-rw

Ooops…it only uses +RW or +R discs.

Exactly.
