I. STANDARDS AND ADJUSTMENTS
A.
Overview
When a breakdown or jam occurs in the unit, the condition of the unit can be checked
by the user LED (LED1: green and orange 2-color light) on the LED PCB and the service
LED (LED201: red light) in the paper deck driver PCB. In combination with the DIP switch-
es (SW201) on the paper deck driver PCB you can check the details of breakdowns and
errors.

Operational Checks to be Performed by the User
The condition of the user LED (LED1) in the unit enables you to check operational
conditions.

mally.
2) Flashing orange light: a paper jam has occurred, a door is open or other condition
requiring operator intervention has occurred.
3) Continuous orange light: breakdown
The user LEDs operate only when the DIP switches are in the following state: SW201-
