Wiring Diagrams and Signal Information
This section of the manual contains a Block Diagram for the N2125 Envelope Feeder. The
Block Diagram shows the interconnections of the major subsystems within the printer. The
remainder of this section divides the Block Diagram into individual block diagrams to better
illustrate the electrical relationships between components and assemblies within the Envelope
Feeder. Each wire in the block diagram is tagged with a signal name, and each wire is termi-
nated at both ends with a pin number.
