Hardware Overview -
Software Functionality - &
There is no required hardware maintenance for the laptop. The end user should never remove the bottom panel of the laptop for maintenance. The bottom panel is sealed by VotingWorks. Additionally, the BIOS is configured to enable "Cover Removal Detection" which means that removing the bottom panel will trigger a sensor and will prevent the computer from booting up without a VotingWorks managed password. As a result, any end user attempt to service their own laptop will result in making the laptop unusable until it is fixed by VotingWorks. Instead of servicing the laptop themselves, end users should report hardware issues directly to VotingWorks to resolve. Hardware issues may include, for example, a screen with defects, a battery that does not charge, or an undetected smart card reader.
VotingWorks recommends cleaning the screen and keyboard as needed. The screen can be cleaned by gently wiping with cleaning wipes such as ULINE S-12236 or equivalent. The keyboard can be cleaned by blowing the keyboard with air in a can, such as ULINE S-6771 or equivalent, from a distance of at least one foot. Read all manufacturer safety instructions before using air in a can.
There are no required steps for maintaining the software or firmware. The software is installed by VotingWorks and cannot be modified. The underlying databases for all applications are self-maintaining and do not need to be tuned by end users.
As VxAdmin and VxCentralScan are used for an election, they will gradually store more and more data. VxCentralScan stores ballot images and interpretations for all scanned ballots and VxAdmin stores imported cast vote records, which often include images as well. It is the responsibility of the election manager using VxAdmin and VxCentralScan to monitor data usage.
The free disk space available on VxAdmin and VxCentralScan is visible to system administrators and election managers by selecting Diagnostics from the side menu. When free disk space hits 0%, the application is no longer able to add data, whether that's in the form of a scanned ballot or imported CVRs. As long as users remain within the specified they should not hit 0%.
When the machine is unconfigured or ballot data is cleared, disk space will be recovered. The free disk space may not appear to return to 100% but old files will eventually be replaced by new files and the disk space will be re-used.
VotingWorks recommends that all scanned ballot data is backed up from VxCentralScan to a USB drive before being cleared from the application. The application forces the user to perform the backup. VotingWorks recommends a 64GB SanDisk Ultra Flair USB 3.0 Drive (PN: SDCZ73-064G-G46) for most operations and the faster 128GB SanDisk Extreme PRO USB 3.2 Drive (PN: SDCZ880-128G-G46) for very large backups. See Retaining and Removing Files - VxCentralScanfor details.

For higher quality reports, VotingWorks recommends paper on the thicker end of that scale such as HP Premium 32lb paper (PN: HPU1132) or equivalent. All report paper should be letter-sized. Using paper outside of the manufacturer specified weight range may result in jams and incorrect operation.
