OCR font type
OCR font type is only enabled when the Machine print checkbox is selected. This setting
allows you to identify specific Machine Print fonts that you are expecting your forms to be
returned in. The default setting of Auto will work for the majority of cases.
Context Checking helps TeleForm recognise characters that are easily confused by using
information from surrounding characters. Generally, if you know that words will be written in a
supported language, or will consist of common names, context checking can help eliminate
confusable characters by checking for improbable character combinations.
Context Checking can be turned off by selecting None. If Context Checking is set to Low,
then any changes made due to Context Checking will be marked for review and held for
approval in TeleForm Verifier. If you are using Context Checking High, then the system will
make the changes required and mark the fields in question as OK and they will not be
marked for review.
As TeleForm evaluates data, it assigns a "confidence" level to indicate its certainty that the
character it selected was correct. Numbers close to "0" indicate low confidence while
numbers close to "100" indicate high confidence. The System level confidence of 80 is
applied by default to all fields.
Generally the higher the confidence threshold is set, the smaller the number of errors passed
through to the database but the more characters will be held for review in the Verifier. The
lower the confidence threshold, the smaller the number of characters held for review but the
greater the chances of incorrect characters being passed through to your database.
The confidence threshold can be set at the system level, the form level or the field level. The
lowest level setting will always supersede the higher level settings, e.g. a field setting will
supersede the form setting. These settings only apply to Hand Print and Machine Print
fields, i.e. Constrained Print and other character recognition type fields. The confidence
threshold does NOT apply to any Choice Fields.
The default confidence level for individual fields of 80% can be changed by:
clicking on the Confidence level drop down box,
selecting Field level, and
changing the percentage to the desired level.

This is where you can set a default value, i.e. the value that’s stored in the database instead
of a missing value. This could be a missing code, e.g. 9, 99, 999, -1.
NOTE: If you want “-1” to be the missing code, you will need to allow for the special
character “–“ (minus sign).
NOTE: The missing code should be a value that cannot be a possible answer for that field.
