Pre-Election Maintenance
In order to keep the scanner in working order, perform routine maintenance before each
election. Before performing the following maintenance steps, ES&S recommends that
the unit be fully powered off using the proper shutdown procedures. Maintenance to
any component inside the scanner requires that the power plug be unplugged from the
scanner. Such maintenance should be done only by trained technicians.
Clean the Rollers
Required Tools:
Dry cotton cloth, isopropyl alcohol
Required Staff:
Personnel trained by ES&S
Required Time:
30 minutes
The rollers move each ballot, picked from the input tray, over the transport path,
through the scan area (upper and lower camera housing), and into one of the three
output bins (the top, middle, or bottom bin). If the surfaces of the rollers are dirty or
discolored, clean them.
To clean the rollers, apply isopropyl alcohol to a cotton cloth and clean the visible
surfaces of the rollers, turning them as you clean to expose most of the surface area of
the rollers.
Clean the Cameras
Required Tools:
Dry cotton cloth, pressurized air can
Required Staff:
Personnel trained by ES&S
Required Time:
5 minutes
To clean the cameras, wipe them with a dry, cotton cloth, or use a pressurized air can to
clean out any debris or paper dust collected during scanner operation. It is important to
hold the can upright so that you do not expel propellant onto the sensors.
Warning:
Make sure you power the scanner down completely and power off and
unplug the UPS before connecting or disconnecting the power cable. Remove the
power cord before moving the scanner. Place the power cord near an easily accessible
unobstructed power outlet.
Caution:
Keep fingers, hands, and loose clothing clear of the rollers.
