The MFX-3510 firmware has been
upgraded and the product now supports manual duplex scanning in the Copy and
Scan modes. Once enabled, this mode allows users to scan two-sided documents
through the automatic document feeder. After the first side of the document(s)
has been scanned, the user will be prompted to turn the documents over and
reposition them in the ADF. The MFX-3510 will then scan the back side of the
document(s) and complete the job.
