摘要： A light collector for directing light to a concentrated area on a target surface such as for use with a linear LED array used as an erase lamp in an electrophotographic printer. The collector includes a compound cylinder lens supported by a pair of reflecting members. The reflecting members reflect light rays from the LED array to the cylinder lens. The cylinder lens includes a lower surface for capturing the reflected light rays and a tongue extending from the lower surface for capturing light rays directly from the LED array. The cylinder lens directs and concentrates the captured light rays in a narrow line on a target surface. A plurality of cross-ribs extend between the first and second reflecting members to specularly reflect light beams from the LED array.

摘要： A distributive pitch skipping method and apparatus for stabilizing productivity in an electrostatographic printing machine. The method and apparatus provide for establishing a first toner concentration (TC) limit at and below which toner image reproduction of the machine stops and the machine dead cycles; establishing a second TC limit, higher than the first TC limit, above which the toner image reproduction rate of the machine is 100% at ST ppm (Standard prints per minute); adding fresh toner into a developer housing of the machine in an attempt to maintain the TC of the developer housing above the second TC limit while running copies having various toner area coverage levels; and establishing at least a third TC limit, between the first TC limit and the second TC limit, above which the toner image reproduction rate is less than 100% at (ST-X1) ppm, and below which the toner image reproduction rate is less than 100% at (ST-X2) ppm, where X1 and X2 are integers, and X2 is greater than X1.
