5045-001 Lubrication Specifications Use Grease (part 1321875) as needed. Do not over grease the parts, but make sure new parts have adequate lubrication. Use of a spray contact cleaner in most instances will allow normal functioning of the fuser sensors which have been contaminated with silicone oil. The only cleaner currently approved by Lexmark is CRC brand industrial contact cleaner # 03130. In addition to the cautions on the Material Safety Data Sheet (MSDS) label attached to the can, observe the following guidelines: • When spraying either fuser sensor (PS9 or PS10), place a piece of absorbent material below the sensor to catch the excess spray. • Use the supplied nozzle and direct the spray into the small apertures in the inside walls of the sensors. • Spray quickly (approximately 1 second applications). This spray leaves no residue, contains no CFCs and is plastic safe. Do Not use a substitute spray that has not been tested and is not plastic safe.
