This object declares for this interpreter the tray switching declaration mechanism used. Note: The tray switching declaration mechanisms do not specify how or when or whether a printer switches back to using an earlier emptied tray after that tray is refilled. For example, assume a printer is set up to first use Tray 1, then when emptied Tray 2, then Tray 3. If just after tray 1 becomes empty and the printer switches to Tray 2, the operator refills Tray 1; the printer may select which tray to pull the next sheet from using a variety of algorithms: - The printer may switch back immediately to use tray 1. This may be particularly appropriate if tray 1 is the high capacity feeder. - The printer may pull sheets from tray 2 until it is empty and then switch back to tray 1. - The printer may pull sheets from tray 2 until it is empty and then continue to tray 3, before switching back to tray 1. Again, implementation of how the input tray switching programs behave when empty trays are refilled is considered printer specific.
