Did you fan the stack before loading?
Before loading a stack of media in the auto sheet feeder, always fan the
pages to remove static cling and align the edges. Fanning the stack sepa-
rates the sheets so they can feed smoothly from the auto sheet feeder.
Check 2
Is the auto sheet feeder overloaded?

the media you are using.
