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

Location of P/J Connectors
Use the P/J table (Table 1) and the P/J Map
connector within the Base Engine.
• Locate the P/J connector number in the first column of the table.
• Locate the corresponding coordinates in the second column, such as I7 or J7.
• Go to the map.
• Cross-reference the letter and number of the P/J coordinates with the letters and numbers
on the map.
• The P/J connector is located within the area where the coordinates cross.
