Sheets Are Curled

Cause:

With sheets that are curled downward and sheets that are not curled, the leading edge of the sheet being delivered rubs against the top sheet of the stack, there being no air gap between the sheets, and the sheet being delivered is therefore prone to get stuck. Consequently, the trailing edge of the sheet being delivered is left in the paper exit, and the next sheet to be delivered slips under the sheet still in the paper exit and bends back.
