Removing and replacing the paper separator
Your document feeder is equipped with a replaceable paper separator, which
causes the document feeder to feed one original at a time. If the separator
repeatedly feeds more than one sheet, or fails to feed a sheet at all, you can
purchase a replacement from your authorized Apple reseller.
To replace the paper separator:
1 Position the document feeder so its front is facing you, and lift the document feeder
cover, as shown.
