Dell P1500 Personal Mono Laser Printer - Manual (Page 23)

An exit output bin on top of the printer holds up to 100 sheets. The single-sheet front output door provides a
straight-through paper path for special media, such as transparencies, envelopes, labels, card stock or index
cards, reducing curling and potential paper jams.
To increase paper capacity, you can purchase the optional 250-sheet tray.
