Please unscrew and throw away

I wonder if this label was made by someone expecting users to be idiots or if some idiots didn't understand that they had to remove this thumbscrew before/when removing the temporary cover inside this $1500 color laser before installing toners... It could lead to some idiot looking for the tiny bin (same size as this thumbscrew) that was supposed to come with the printer, or is it really that clear? Rotate counterclockwise and pull up while pushing the bin down.
