It should, but it doesn't so this is the only way to avoid black toast.
My brother's toaster isn't far off that, actually. It has a knob that makes it toast for longer, depending on perhaps the bread thickness, but more likely just preference.
It also has a button that extends the time if your bread is frozen.
It has another button that reduces the time, maybe if the toast is already done, or if you're reheating the toast because you answered the door or something and it went cold. Maybe also it's there for if the toaster's warm already.
It has another button but I don't know what it's for. I need to find the manual!
