We demonstrate the existence of a simple scaling form which describes the crossover from anomalous to Gaussian exponents as a function of cutoff in the Zhang model of surface growth for $\mu > 2$, where $\mu$ is the exponent characterising the power-law noise distribution. For $\mu = 2$ we find a novel scaling form with logarithmic corrections. Our results for cutoff scaling at $\mu = 2$ are supported by the scaling of the saturation growth velocity.
