摘要： A device and method for blocking light from a laser light beam assembly in a printer, copier, or facsimile machine. Light is blocked from contact with the nonprint region of the photoreceptor drum in a toner cartridge to prevent toner spotting on the output paper and toner leakage in the cartridge and machine. A nontransparent piece of plastic material preferably rectangular in shape is sized to block a part of the light access slot on the toner cartridge cover corresponding to the nonprint region of the drum. The device is secured to the underside of the cover. A method for accurately positioning the nontransparent piece of material to block the required part of the access slot uses a long, flat tool of set length. One end of the tool is placed adjacent to a side wall on the right side of the underside of the cover and the tool is layed over the access slot. The nontransparent piece of material is placed adjacent to the opposite end of the tool and secured by an adhesive, such as two-sided tape, to the underside of the cover. Thus, light is blocked on the left end of the access slot for a distance necessary to keep light from contacting the nonprint region of the drum.
