Cassette+and+Tray

=What does Canon mean by the terms Cassette and Tray?=

Cassette
The place where you load a stack of paper and insert into the printer beneath the ouput area. Usually called a tray by most other printer makers. Only present on the iPF5000 and iPF5100, not the larger printers.

Tray
A vertical slot at the top of the printer for feeding single sheets. No one knows why it would be called a tray. Present on all iPF large format printers.
