Abstract
Abstract An electrostatographic machine which includes means for forming an electrostatic latent image on an imaging member; means for developing the electrostatic latent image with a developer material; means for transferring, at a transfer station, the developed image to a copy sheet; a copy sheet system for conveying copy sheets to and from the transfer station and means for fusing the developed image to the copy sheet. The copy sheet system is withdrawable from the rest of the machine as a module comprising substantially the entire path through which copy sheets are moved during operation of the machine.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
Electrostatographic machine comprising: a first portion including means for forming an electrostatic latent image on an imaging member; means for developing the electrostatic latent image with a developer material; and means for transferring, at a transfer station, the developed image to a copy sheet; and a second portion comprising a module which is slidably mounted at one side of the first portion directly adjacent said transfer station, the module being separable from the first portion by being pulled out of the front of the machine; the module including a copy sheet supply, a fuser for fusing developed images to the copy sheets, a copy sheet output receiver, and a copy sheet transport system for conveying copy sheets from the supply to the transfer station, from the transfer station to the fuser, and from the fuser to the output receiver.
Claim 2
Dependent Claim
139 words
Electrostatographic machine comprising: a first portion including means for forming an electrostatic latent image on an imaging member; means for developing the electrostatic latent image with a developer material; and means for transferring, at a transfer station, the developed image to a copy sheet; and a second portion comprising a module which is slidably mounted at one side of the first portion directly adjacent said transfer station, the module being separable from the first portion by being pulled out of the front of the machine; the module including a copy sheet supply, a fuser for fusing developed images to the copy sheets, a copy sheet output receiver, and a copy sheet transport system for conveying copy sheets from the supply to the transfer station, from the transfer station to the fuser, and from the fuser to the output receiver.
Claim 3
Dependent Claim
30 words
The machine of claim 1, wherein the path of copy sheets through said module turns through substantially 180° between a copy sheet supply container and a copy sheet output receiver.
Claim 4
Dependent Claim
31 words
The machine of claim 1, wherein the imaging member comprises a photoconductive member within a removable cassette, and wherein the transfer station constitutes the interface between said module and the cassette.
