          Appeal No. 2001-0345                                                        
          Application 09/041,416                                                      


               Rather than repeat the positions of the appellants and the             
          examiner, reference is made to the brief and the answer for the             
          respective details thereof.                                                 


                                       OPINION                                        
               We sustain all the separately stated rejections of all the             
          claims on appeal under 35 U.S.C. § 103.                                     
               At the top of page 8 of the brief, appellants indicate that            
          all claims fall together.  More significantly, however, no                  
          arguments are presented in the remaining pages of the brief as              
          to any separate claim on appeal.  As such, we take as a                     
          representative claim, for purposes of rendering this decision,              
          claim 1 on appeal.  Substantive arguments are presented by                  
          appellants only as to Doyle, Raschke and Calabrese.                         
               We note initially that the conventional approach for                   
          electrophotographic printing systems is to first place an                   
          electrical charge on the substrate, then fix or image it                    
          selectively, followed by the application of toner.  In contrast             
          to this approach, the subject matter of the disclosed and claimed           
          invention requires the substrate to be charged over its entire              
          surface, the application of toner (in liquid form) on the                   


                                          3
