Patch Reading | Patch reading allows you to change image address (IA) information |
| for a document on the fly, without any host PC or Operator Control |
| Panel intervention. All documents with patch codes are imaged and |
| cannot be automatically deleted by the scanner. |
Types of Patch Codes | A patch code can change the IA level of the document that the patch |
| code occurs on (or the following document in the case of a Transfer |
| patch). These changes then override the IA calculated using the Level |
| to Follow Level rules. |
| Type 3 Patch Code |
| The image header reflects when a Type 3 patch code is detected |
| on a document. A Type 3 patch code is considered to be a Level |
| 3 document. The IA for that document is recalculated by |
| incrementing the Level 3 field and setting the Level 2 and Level 1 |
| fields to 0 (if the Level 2 and 1 fields are defined as having a field |
| width greater than 0). In the image header, document level and |
| patch type will be returned as a 3. |
| Type 2 Patch Code |
| The image header reflects when a Type 2 patch code is detected |
| on a document. A Type 2 patch code is considered to be a Level |
| 2 document. The IA for that document is recalculated by |
| incrementing the Level 2 field and setting the Level 1 field to 0 (if |
| the Level 1 field is defined as having a field width greater than 0). |
| In the image header for this document, document level and patch |
| type will be returned as a 2. |
