OPERATOR PANELS
This chapter describes the function of the operator panels. It is useful to 
describe the Status Monitor software at this point as it provides the B4100 
and B4250 status information and the equivalent of the menu control 
panel on the B4350 and B4350n. (See “Printer Drivers” for installation of 
the Status Monitor.)
