Canon S400 Print Problems

[Anonymous]

with my canon s400 i can print, but bottom of page (last 1/1.5 cm) isn't printed.
i tried to use allignps utility but it doesn't solve problem.
what can i do???
someone can help me????
it isn't a great problem, but to print some important documents, i must use winzozz.
