I have a Pixma TS7450a

I want to copy  15  double sided pages but it keeps printing with page 3 on the back of page 1 and 2 on back of 4 etc etc.   Can somebody explain how to do this and what I am doing wrong?

Many thanks!

OK   sorted it out for myself !!

Greetings,

Selecting two-sided short edge can cause scanned pages to print back double-sided out of order.
