One Transfer Roller assembly
Seven Feed rollers (two per tray, includes rollers for Tray 4 and one roller for Tray 1)
Three Pickup rollers (one per tray, includes roller for Tray 4)

(http://www.hp.com/support/ljpaperguide) for more information about suitable media, environment, and use conditions.
