For (square) and small slices of toast no problem - Stage 2 -3 depending on the desired browning degree.
Normal course Large slices of bread do not fit purely without allowing out are a side diagonally upwards.
But in an emergency, the devil eats flies ;-) I have developed an alternative way ...:
Four slices of bread (normal size) edgewise - two slices each slot once toasting stage 2
then turn around all 180 degrees and toast again.
That are twice after toasting 4 slices ready ... that can in the time hardly a great toaster for 120, - keep up!
This unit has 2 slots!
