This mode can be entered from the Hidden Service Menu. All diagnostics are
available in this mode.
The printer reboots after entering or exiting all diagnostic modes. The printer
will keep the printer thermals hot during diagnostics to avoid unnecessary
cleaning cycles. If a diagnostic test runs into a problem while initializing the
heaters a message will display, "Test Fault, can't warm up - press any button",
you can still continue to run diagnostics under this condition.
Note
If the heaters are On while entering diagnostics, they will remain On while
diagnostics are being run. If the heaters are Off while entering
diagnostics, they will remain Off. Utilize the Exercise Heaters function if it
is necessary to turn On/Off the heaters.
