3.5 Block Diagram
Most of the circuitry in the Printer is on the CPU PCBA. Since the CPU PCBA is not a
serviceable unit, circuit analysis to the component level is pointless.
Below is a block diagram of the functional circuits of the Printer; the block diagram also
shows how signals are passed to and from the CPU PCBA to the rest of the Printer.
