To choose a variant, scan one of the following bar codes. Selecting the following OCR-B variants automatically sets
the appropriate OCR Lines on page 13-12. These five variants invoke extensive special algorithms and checking
for that particular document type:
Variant OCR Lines Setting
Passport 2
TD1 ID Cards 3
TD2 ID Cards 2
Visa Type A 2
Visa Type B 2
Selecting one of the ISBN Book Numbers automatically applies the appropriate ISBN checksum, so you do not
need to set this.
For the best performance in passport reading, fix the target passport and the imaging engine in place (6.5 - 7.5”).
NOTE Enable OCR-B before setting this parameter. If disabling OCR-B, set the variant to its default
(OCR-B Full ASCII).
