8.5 SHUTDOWN INPUT
The shutdown input (J3, pin 5) is designed to be used with an Active Low input such as the ignition
connection in a vehicle. The user shutdown function is disabled as standard, the printer defaults to
awake at power on.
To allow the user shutdown feature, the position of the jumper at site JP4 must first be altered,
following this applying a voltage of +2V to +36V on the shutdown pin will keep the printer awake
otherwise the printer will enter the sleep state. The supply current drawn from the V+ rail is
approximately 600uA (at 12V) while the printer is shutdown.
To enable the user shutdown feature, please follow the steps below.
1. Unscrew the bottom PCB from the printer and pull the 2 PCB’s apart:
2. Move the jumper at site JP4 away from the position marked “W” as shown:
3. Push the two PCB’s back together and screw them back in to the printer, making sure not
