Printing on custom-size paper
When printing on custom-size paper, if Tray 1 is configured in the printer control panel as TRAY X TYPE= ANY TYPE and TRAY X SIZE= ANY SIZE, the printer will print on whatever paper is loaded in the tray.
Some software applications and printer drivers allow you to specify custom paper-size dimensions. Be sure to set the correct paper size in both the page setup and print dialog boxes. If your software does not allow this, specify the custom paper-size dimensions in the Paper handling menu of the printer control panel. See Paper handling menu for more information.
