Xerox WorkCentre M20, 4118, FaxCentre 2218 Family. Service Manual
The WorkCentre 4118P and WorkCentre 4118X have been introduced. These are variations of the Xerox WorkCentre M20. Throughout this service manual, procedures and parts that are unique to either the WorkCentre M20 family or the WorkCentre 4118 family will be designated M20F or 4118. This issue of the service manual was updated at a time when the introduction of RoHS (Restriction of Hazardous Substances) compliant parts was initiated. Due to these factors, extensive changes have occurred to the part numbering within the parts lists.
This manual is part of a multinational service documentation system that is structured in the standard Xerox service manual format. This manual is based on a Korean original. The part names used throughout do not comply with the standard Xerox part naming convention. Because part names have been molded on to some plastic components and may also be embedded in the software, the part names have not been changed. To aid part identification, an acronym list and cross reference lists of more commonly recognised part names have been included in the manual. Refer to GP 20, Acronyms and Parts Description List.
