I had an email from a client asking about the MP C501SP. The first thing I stated is that the MP C501SP has A4 print capability only. It does have 11x17 scanning, and emailing.
The client responded with no 11x17? I was going to email him back a yes and then remembered that we can set up a workflow for scan2print. In this case we would set a workflow button on the home screen that would then send that 11x17 document(s) to print to an A3 device on the network. Deals not done, however it's a great start.
