1. Outline
If malfunction or paper jam occurs in the paper deck, the condition of the paper deck can be
checked with the Status LED (LED301: on the LED PCB) and Service LED (LED202: on the paper
deck driver PCB). The service mode can be switched by changing the combination of the test
switches (SW201:DIP switches) on the paper deck driver PCB. Using the stand alone mode
switch in the power supply unit, the paper deck can be operated without the printer.
The Status LED can display the following 3 conditions of the paper deck.
1) Green light ON: The paper deck and printer are communicating normally.
2) Orange light flashing: Operator's intervention is required due to paper jam, door open, etc.
3) Orange light ON: Malfunction has occurred.
Note: The Status LED is effective only when all the test switches are OFF (the condition set at
the time of shipping from the factory).
