How to Start Self-Diagnosis
How to Start Self-Diagnosis
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 diag-
nostic 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.
1. Power supply to the printer is off
2. Switch on the power with the [Head Cleaning] + [Menu Display] + [Shift] keys
held down.
3. The panel LCD will display “DIAG: EXAM”. X and Y excitation remains off.
Note 1:
The system will not revert to normal mode even if there is no key entry for
three minutes.
Note 2:
Roll media mode is set automatically.
Note 3:
Panel keys that can be operated are [CANCEL] and the keys for menu
display (Menu Up and Down, Back, Value + and –, ENTER)
Note 4:
To terminate self-diagnostics, switch off the power.
Note 5:
To feed media, press [MENU] while holding down the [Shift] key when the
Diagnostics Menu is displayed.
