1-2. Operator Call Error (Alarm LED Lit In Orange) Troubleshooting
Errors and warnings are displayed by the following ways:
- Operator call errors are indicated by the Alarm LED lit in orange, and the error and its solution
are displayed on the LCD in text and by icon.
- Messages during printing from a computer are displayed on the printer driver Status Monitor.
- Error codes (the latest 10 error codes at the maximum) are printed in the "operator call/service
call error record" area in EEPROM information print.
Buttons valid when an operator call error occurs:
- ON button: To turn the machine off and on again.
- OK button: To clear and recover from an error. In some operator call errors, the error will
automatically be cleared when the cause of the error is eliminated, and
pressing the OK button may not be necessary.
- Stop button: To cancel the job at error occurrence, and to clear the error.

1-3. Service Call Error (by Cyclic Blinking of Alarm and Power LEDs)
Troubleshooting
Parts that are
likely to be faulty
- Ink tank
- Spur unit
Service call errors are indicated by the number of cycles the Alarm and Power LEDs blink, and the
corresponding error code with the message, "Printer error has occurred. Turn off power then back on
again. If problem persists, see the manual." is displayed on the LCD.
y Check each point in "Check points & Solution," and perform the solution if it applies.
y When no solution in "Check points & Solution" is effective, then replace the part listed under
"Parts to be replaced" one by one from the one most likely to be faulty. The parts are listed in the
order of likeliness to be faulty.
