When the printer has been left in power off state for more than one month (31 days) , user unrecoverable error is displayed. When the service clean (for long term storage) is performed before turing the printer off, this error is not displayed. When the head wash (return sequence after service clean) is performed, the printer returns to the ormal error observation state. This error cannot be cleared by normal power ON/OFF.
Turn the printer on by error skip mode (CANCEL +SHIFT + POWER ) , input the passward, and initialize the internal error flag. Clear the error by turning the printer off (not turning the breaker off) and turning the printer on again.
