Diagram 104A, above, illustrates HP IIISi. The HP IIISi and 4Si differ from the Canon-NX (Diagram 104) in that the formatter is housed in a pan assembly on the right side of the printer. This difference forces the connections to the DC power supply and DC controller to be different, which is why there are different DC controller and different DC power supplies.

Item 9 was revised and slightly improved with some additional high-voltage capacitance in the AC line filtering circuit. All newer NX printers came with the newer part (higher numbered assemblies) and all older printers came with the older assemblies (lower numbered). In applications where the AC power isn't very clean and has switching spikes the newer version may be a bit more fault tolerant. For most people who have clean AC power in their buildings, there will not be any performance difference.
