A light scanning unit assembly, an electrophotographic image forming apparatus including the light scanning unit assembly, and a method of adjusting a scanning line skew. The light scanning unit assembly includes a frame, a primary light scanning unit and at least one secondary light scanning unit each being mounted to the frame to scan a corresponding beam, and a skew adjuster to adjust a scanning line skew of the at least one secondary light scanning unit to equal a scanning line skew of the primary light scanning unit. In the light scanning unit assembly, the skew adjuster includes at least one side to project out from at least one side of the at least one secondary light scanning unit, at least one adjusting screw to connect the at least one side projection with the frame, and at least one elastic member interposed between the at least one side projection and the frame. The scanning line skew adjustment method includes mounting the primary and the at least one secondary light scanning units on the frame and manipulating the at least one skew adjuster such that a scanning line skew of the at least one secondary light scanning unit is equal to a scanning line skew of the primary light scanning unit. The skew adjustment operation includes adjusting the scanning line skew of the at least one secondary light scanning unit to coincide with the scanning line skew of the primary light scanning unit by rotating the at least one adjusting screw.

An image forming apparatus is provided having a printing unit including a detachable developer cartridge. The apparatus prints an image on a sheet using an electrophotographic process. A tray is provided to receive a sheet discharged after the completion of printing. An auxiliary tray is pivotably installed on the tray and has a first position folded over the tray and a second position to increase the length of the tray. The auxiliary tray pivots to the second position when the developer cartridge is mounted in the printing unit.
