just for curiosity went to ricoh's warranty page.
the one year basic warranty says nothing about non transferability
only the EXTENDED warranty explicitly states "non transferrable" with several mentions of "original purchaser'
so one COULD conclude that the basic one year warranty follows the product as long as a valid receipt showing original purchase date is included in the transaction.
