POSTSCRIPT MODEAuto-tray switching Specified by the TraySwitch parameter. Auto-tray switching isimplemented if TraySwitch is enabled and a tray runs out ofpaper after the job starts. The order in which auto-tray switchingoccurs is: 4, 1, 2, 3.Default tray sequence PostScript searches the tray selection by paper size and media, asshown in table 1-2. The default sequence in which the size issearched for is: 4, 1, 2, 3, 5.Table 1-2.

In Duplex mode, Tumblemode can be selected. When Tumble true is selected, the imageon the reverse side of the page is printed upside-down, making itsuitable for top binding. When Tumble false is selected, theimages on the reverse side are of the same orientation, makingthe pages suitable for left binding. Top and left can be either thelong or short edge.With most Level 1 implementations, the tumble effect is not thesame for landscape and portrait jobs. However, for bothorientations, setting Tumble true generates short edge binding,and setting Tumble false generates long edge binding.N Note: This differs from the Level 2 use of Tumble or Landscapepages.For all duplex jobs, the first duplex page is always printed on thefront of the physical page. If the last page of a job uses onlythe first side of the paper, this page is delivered automaticallywhen Duplex mode is deactivated or a timeout occurs.Since Level 1 statusdict operators which set Duplex and Tumblemodes persistently are not implemented, these operators cannotbe used in the print data to override the Duplex mode or Tumbledefaults. These defaults can be changed with the Level 2operator setpagedevice.1–6 XEROX MRP FAMILY PCL 5 AND POSTSCRIPT PRINTER LANGUAGE REFERENCE
