You can use "\C-l" for this.

The page starts right after the page separator, so with some more annotation:
(with-temp-buffer
(insert "Page 1/3 line 1
\C-l page 2, line 1
Page 2/3, line 2
\C-l, page 3, line 1
Page 3/3, line 2")
(forward-page)
(count-lines-page))
You can see that pages 2 and 3 both have two lines.
