Diagnostics
Three types of built-in diagnostics support are available.
•
Power-up diagnostics run automatically each time the
NCR 7800 is powered up or reset; they check RAM
motor speed, laser operation, and stepper motor operation
(if equipped).
•
Real-time diagnostics continuously check specific
components during operation.
•
Extended diagnostics may only be run by the user at
power-up.
A built-in demonstration mode may also be useful for
operation testing. Refer to the Demonstration Mode section at
the end of this chapter.
