10 Authentication unit (biometric type)
This chapter describes the authentication unit (biometric type).
1. Authentication unit (biometric type) AU-101
2. Authentication unit (biometric type) AU-102
10.1 Using an authentication unit (biometric type)
The authentication unit (biometric type) is a biometrics (biometric authentication) system that scans a finger 
vein pattern to perform personal authentication. Using the biometric authentication, you can log in to this 
machine where user authentication settings are configured in order to execute a print job.
Place your forefinger straight so that your forefinger cushion slightly touches the hollow and protuberance 
part of the scanning section. Secure your middle finger and thumb on the both sides of the authentication 
unit to prevent your forefinger to be used for authentication from rotating.
For details on how to place your forefinger on the authentication unit, refer to page 10-17.
NOTICE
If you change the authentication unit from AU-101 to AU-102, the users you registered with AU-101 cannot 
use AU-102. Connect AU-102 to this machine, and then register the users again.
Do not place anything other than your finger on the scanning section during scanning operation. Doing so 
may cause a malfunction.
Do not disconnect the USB cable from the authentication unit or computer during a scanning operation. 
Doing so may cause the system to become unstable.
The status indicator LED and notice sound indicate the status of the authentication unit.
