If this does not improve the print quality, install a new toner cartridge. • The paper may not meet paper specifications; for example, the paper may be too moist or rough (See "Print media specifications" on page 71). • A combination of faded or smeared defects may indicate that the toner cartridge needs cleaning (See "Cleaning the inside" on page 48). • The surface of the LSU part inside the machine may be dirty (See "Cleaning the inside" on page 48).
