When you use the staple finisher-P2 or booklet finisher, you need to select which one to use when printing.
Select the following menu.
If you select Auto, the printout destination is set to the finisher tray.
You can specify whether or not to use the finisher tray from the Output Tray menu on the printer driver. If you select Auto Select, the printout destination is set to the finisher tray.
Even if you select a printout destination on the printer's control panel or the printer driver, the printout may be automatically sent to another output tray depending on the paper size or type.
When using the finisher tray, do not remove your printouts while the print job is still in progress. The print position may be misaligned and the staple position may move from its original position.
