Sorting or Staple-sorting Stops

different copy exposures on the front and rear sides of the paper. Also, the sorting
of LTRR-size copies may stop depending on the copy exposure. When this
happens, the following message is displayed.
Copying will automatically resume after you remove the copies from the bins.
