In loop quantum cosmology, the universe avoids a big bang singularity andundergoes an early and short super-inflation phase. During super-inflation,non-perturbative quantum corrections to the dynamics drive an inflaton field upits potential hill, thus setting the initial conditions for standard inflation.We show that this effect can raise the inflaton high enough to achievesufficient e-foldings in the standard inflation era. We analyze thecosmological perturbations generated when slow-roll is violated aftersuper-inflation, and show that loop quantum effects can in principle leave anindirect signature on the largest scales in the CMB, with some loss of powerand running of the spectral index.Comment: revtex4, 5 pages, 3 figures, significant improvements in explanation  of quantization and perturbation issues; version to appear Classical and  Quantum Gravit
