Theory of operation

POR sequence

As the printer turns on, the engine code goes through a series of tests to verify hardware integrity. If a hardware
failure is detected, then it is reported to the printer. If the POR sequence cannot be completed successfully,
then the printer may post an error message. The message states that service may be needed.
