The releasably removable image receiving module is configured to engage the support structure of the system such that the image receiving substrate of the module can be disposed in an operative relationship with the developing stations when the removable module is engaged with the support structure. This imaging system provides a method for upgrading, downgrading or modifying the imaging system that could be substantially performed by an end user. This imaging system may be embodied in a monocolor or multicolor printer, copier, facsimile machine or other electrophotographic based apparatus. ## Claims ### Claim 1 An imaging system comprising: a plurality of developing stations for developing an image on a sheet; a releasably removable image receiving module having an image receiving substrate and a plurality of exposing unit mounting elements, each of the plurality of exposing unit mounting elements capable of receiving an individually removable exposing unit; and a support structure for receiving the releasably removable image receiving module, releasably removable image receiving module being configured to be engageable with the support structure and the image receiving substrate being disposed in an operative relationship with the developing stations when the releasably removable image receiving module is engaged with the support structure. ### Claim 2 (depends on 1) The invention according to claim 1 wherein the image receiving substrate is a substantially transparent photoreceptor. ### Claim 3 (depends on 2) The invention according to claim 2 wherein the image receiving substrate is formed as a belt. ### Claim 4 (depends on 2) The invention according to claim 2 wherein the image receiving substrate is formed as a drum. ### Claim 5 (depends on 1) The invention according to claim 1 wherein the exposing unit comprises a LED array. ### Claim 6 (depends on 1) The invention of claim 1 wherein the releasably removable image receiving module further includes at least one individually removable exposing unit mounted on a respective one of the plurality of exposing unit mounting elements. ### Claim 7 A method for upgrading an imaging system, the imaging system including at least one developing station and having a support structure, the method comprising: providing a releasably removable image receiving module having at least one exposing unit and an image receiving substrate, the releasably removable image receiving module being configured to be engageable with the support structure such that the image receiving substrate is disposed in an operative relationship with the at least one developing station when the releasably removable image receiving module is engaged with the support structure;
