Hart eSlate DREs & eScan OpScans had a terrible time with the volume test, it seems. Yet the DREs were recommended.
Based on one federal spec alone, a Mean Time Between Failure (MTBF) rate of 163 hours, I don't think the the Hart eSlate qualifies. (As a side note, that spec is woefully inadequate as it is.)

eSlate Volume Test
The Secretary of State staff and technical consultants Steve Freeman and Paul Craft
conducted the volume test of the Hart eScan and the eSlate on February 21st and 22nd,
2006, at the Orange County Registrar of Voters’ warehouse.

(For the test they set up) one hundred eSlates equipped with the VBO AVVPAT.

A total of thirty-four errors were logged during the eSlate volume test. Twenty-four of
those errors were related to the actual performance of the eSlate equipment.
During testing, four eSlate units got stuck in some kind of an error cycle that could not be
exited. Generally this occurred when trying to cast the ballot. At the time of saving the
ballot, the VBO would print "ballot cancelled" repeatedly on the audit record and the
screen controls would freeze. After rebooting the machine, the same symptoms
reappeared on the next attempt to cast a ballot. The vendor initially hypothesized that a
defective power adaptor or connector for the power adaptor caused the problem. After
swapping out the adaptors, two machines were retested and exhibited the same problems.
All four machines were taken out of service and not tested further. It should be noted that
all four of these exhibited these symptoms within the first five ballots, indicating the
possibility that this is a manufacturing problem that can be detected with robust
acceptance testing. We are awaiting further explanation from the vendor as to the cause
of this problem.
There were seventeen incidents of problems with the VBO AVVPAT printer. In one
incident, the eSlate locked and displayed the error message “EVBO-101” The vendor
explained this error code represents a printer battery error. This VBO was opened and
the batteries were disconnected, after which voting resumed normally on the eSlate. In a
second incident, the eSlate locked with the printer error "EVBO-103." The vendor
explained this error code represents a printer communication error. This VBO was
swapped out and taken out of service in accordance with the Use Procedures for this
system.
In the remaining fifteen occasions of VBO errors, the eSlate locked up with the screen
displaying cryptic error message: "Printer error EVBO-102". Per the vendor, this error
code represents an out-of-paper condition in the VBO. In two cases (incidents #32 &
34), this was correct - the VBO was out of paper. In the thirteen remaining instances, this
was a false out-of-paper error. In each case, the vendor was able to correct this by
removing and disassembling the VBO, and then advancing the paper, after which voting
resumed normally on the eSlate without further errors. In all such cases, the error was
triggered within the first ten ballots. It should be noted that the VBO is designed to not
be opened in the polling place, and if any issues arise, to be swapped out and replaced
with a new unit.
Overall, there were seventeen instances out of 100 eSlates that would have required the
replacement of a VBO in a polling place. Should this system be certified, use procedures
should require an appropriate number of VBO replacements to be on hand in each polling
place.
The remaining ten incidents were all attributed to human error:
• In one case, the assigned activation code for a ballot timed out before the voter
could use the code.
• In five cases, the voter was issued an activation code for the wrong ballot style.

• In four cases, the error was attributed to voter confusion on the test process or
operation of the eSlate.
Based on the volume test results for the eSlate, the Office of Voting Systems
recommends that if this system is certified, the Use Procedures should specify:
• robust acceptance testing procedures that will identify any defective units subject
to the error cycle/lockout problem that caused the four units in the volume test to
be taken out of service
• an adequate supply of replacement VBO units on hand at each polling place to
ensure that there is no downtime of eSlates due to VBO failures
Further, as soon as possible the vendor should a) resolve the problem that causes the
VBO to falsely indicate a low paper condition at the start of the role, and b) replace the
cryptic error codes on the eSlate with plain-text, understandable error messages that
communicate to the voter and the poll worker what the problem is, how to resolve the
problem and the status of that voter’s ballot. These must be accomplished as soon as
possible to enhance voter confidence in this system.
