Programmable Keys; Patch Reading - Kodak i1800 Series Image Processing Manual

Programmable keys

Patch reading

Patch code types
2-22
Programmable keys are available for use by the operator when the
scanner is enabled. The touchscreen displays the functions that are
associated with these programmable keys. The programmable keys
can be assigned the following functions:
• No scanner functionality (default)
• End Batch
• Omit Multi-feed
• Omit Printing
• Omit Patch
Patch Reading information, associated with image addressing, only
applies when the scanner is configured with Image Address enabled
via the operator control panel touchscreen.
Patch reading allows you to change image address (IA) information for
a document on the fly, without any host PC or touchscreen intervention.
All documents with patch codes are imaged and cannot be
automatically deleted by the scanner.
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 document containing 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 document containing 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.
