If you advance the self timer to the first white mark (6 second point) without cocking the shutter or if you cocked the shutter but tripped it yourself before the self timer actuates the shutter, the self timer will pause with the self timer lever at about the 10 o'clock position. I can then cock the shutter one time but cannot trip it with the self timer lever at that position. Instead, you have to reset the self timer past the first white mark again, push it's small release button and have it trip the shutter this time. At least this is how my XE-7 operates which should be the same as the XE-1 if all is functional.
