    35 RES Save Off 
    Deficient MemoryThis message displays when the printer lacks sufficient memory to enable Resource 
    Save. This message usually indicates the user has allocated too much memory for 
    one or more of the printer link buffers; however, modification of other printer settings 
    which affect the amount of available memory may also create this condition. If 
    restoration of Resource Save is required after this message is received, the customer 
    should install additional memory or set each link buffer to Auto. Once all link buffers 
    are returned to Auto, you should exit the menu to activate the link buffer changes. 
    Once the printer returns to the Ready state, you can enable Resource Save and go 
    back and modify the link buffers again. Note the reduction of available memory to the 
    link buffers when Resource Save has been enabled, and compare it to the memory 
    available when Resource Save is disabled.
    
     Select ( ) to disable Resource Save and continue printing.
    To enable Resource Save after you get this message: 
    - Make sure the link buffers are set to Auto, then exit the menus to activate the
