Configure VxScan

Before you can configure VxScan, you will have to setup the machine. You may follow the steps in the Poll Worker VxScan Setup Guide:
VxScan Setup
In order to configure VxScan, you will need to prepare two things:
1.USB Flash Drive with the appropriate ballot package. You may follow the instructions for exporting a ballot package from VxAdmin.
2.Admin Card programmed for the appropriate election. You may follow the instructions for encoding Admin Cards.
Loading The Ballot Package
An unconfigured machine will prompt you to insert a USB drive with the election's ballot package:
After you insert the USB drive,  VxScan will begin loading all ballot styles for the election:
 If the USB drive contains multiple ballot packages, VxScan will use the most recent.
After the ballot package is done loading, you will land on the Polls Closed screen in Live Election Mode:
Setting Precinct
After configuring, VxScan will be setup for All Precincts, which means that it will accept and tabulate ballots from all precincts. If you are using VxScan to service a vote center or otherwise have more than one precinct's voters casting ballots at a single location, then you may want to leave VxScan set to All Precincts. 
In most cases, you will set VxScan to only accept ballots for one precinct. In order to do so, you will need the Admin Card configured for the current election. Insert the Admin Card into the card reader on the back of the VxScan's screen, with the front of the Admin Card facing the opposite direction as the screen. VxScan will then display the admin screen. Tap the precinct button to open a list of all precincts:
Select a precinct in the dropdown list: 
Your chosen precinct will appear on the precinct button and in the lower left-hand corner of the screen:
Setting Mode
Use the toggle button switch between Testing Mode and Live Election Mode. You will want to put the machine in Testing Mode before Logic and Accuracy Testing and return it to Live Election Mode at the very end of Logic and Accuracy Testing. 
Switching to "Testing Mode"
Calibrating the Scanner
Before each election you must calibrate the VxScan's sensors to ensure the scanner accurately identifies marks. It may be easiest to incorporate calibration into Logic and Accuracy Testing. Calibration requires a sheet of blank paper of the same type as your ballots.
To begin, tap the Calibrate Scanner button on the admin screen:
VxScan will prompt you to insert a blank piece of paper before calibration can start:
When you insert a piece of blank paper, the scanner will grip the paper and an option to Calibrate will appear. After tapping that option, VxScan will slowly process the piece of paper.
After calibration is complete, don't forget to retrieve the blank piece of paper from inside the ballot bag! If you are doing calibration during Logic and Accuracy Testing, you may choose to leave the paper in until you retrieve testing ballots and confirm the ballot bag is empty at the end of testing.
