Page size is established.If page size is not sent by the application, the PCL Menusetting called Paper Size is used.2. Paper source is established.If a paper source is sent by the application, it will be oneof the six PCL paper sources listed in Figure 2.16.If paper source is not sent by the application, the PCLMenu setting called Default Source is used. Somesoftware applications have a paper source called “AutoSelect” or “Auto Sheet Feed.” When used, this results ina PCL paper source being omitted from the print job.3. When the printer is ready to print the page, tray sequenceis established.For the paper source chosen in the second step above, atray or sequence of trays is taken from the PCL MenuSource Mapping setting for that source. For settings, seeFigure 2.18 (page 2-35).4. The printer searches in the tray or in any tray in the traysequence for the correct page size from the first stepabove.In a tray sequence, the trays are searched left to right asthey appear in the Source Mapping setting. For example,for sequence Up-Mid-Low, the upper tray is searchedfirst, the middle tray second, and the lower tray third.5. If a tray with the correct paper size is found, the page isprinted from that tray.If no tray with the correct paper size is found, the traysequence and paper size are displayed on the ControlPanel along with a message to load the correct paper size.Printing halts.Printing a PageWUG-CH02 Page 31 Black,Red,Cyan Sunday, January 22, 1995 7:32 PM
