5. SELF-DIAGNOSIS FUNCTION
5.1 INTRODUCTION
These pages deal with the hidden diagnostic functions of the Inkjet Printer. These hidden diagnostics are
mainly intended for examining boards and determining mechanical and firmware adjustment parameters.
These functions are incorporated into the printer firmware but they are not disclosed to end users. They are
enabled by applying power to the printer while holding down several special panel keys. It is not possible to
access the hidden diagnostic functions from the normal printer mode. Updated firmware adjustment
parameters can be registered by exiting diagnostic mode or by switching off the power. Firmware adjustment
parameters are also registered when there is a serious MOE failure error on adjustment. The printer will be
reset on exiting diagnostic mode. Diagnostic functions are as follows.
