To select the minimum number of OCR characters (not including spaces) per line to decode, scan the following
bar code, then scan a three-digit number between 003 and 100 using the Numeric Keypad from the Advanced
Data Formatting Programmer Guide representing the number of OCR characters to decode. Strings of OCR
characters less than the minimum are ignored. The default is 003.
OCR Maximum Characters
Parameter # 690 (SSI # F1 B2h)
To select the maximum number of OCR characters (including spaces) per line to decode, scan the following
bar code, then scan a three-digit number between 003 and 100 using the Numeric Keypad from the Advanced
Data Formatting Programmer Guide representing the number of OCR characters to decode. Strings of OCR
characters greater than the maximum are ignored. The default is 100.
OCR Security Level
Parameter # 554 (SSI # F1 2Ah)
To select the OCR decoding security/confidence level, scan the following bar code, then scan a two-digit
number from the Numeric Keypad from the Advanced Data Formatting Programmer Guide representing the
level of confidence. Greater numbers minimize OCR decoding errors but reduce performance. Setting a value
that is too high can result in failure to decode. Setting a value that is too low can cause decoding errors. The
range of the security level is 10 - 90 and the default is 80.
