There are three major reasons for using scan codes on documents.
Process Variable Sheet Collations
Before the introduction of scan codes, customers needed to print all of their
single page, 2-page, 3-page, 4-page, statements etc. as separate print jobs.
Then they would run them through their inserter as separate jobs. Scan marks
greatly reduced this time-consuming process by allowing variable sheet col-
lations sets to be run through an inserter from one print job. Use of a scan
mark to indicate the last page of a collation allows users to specify a different
number of pages in each outgoing collation. This requires an End-of-Collation
(EOC) mark, and this mark is required for all scanning applications.
Assure Mail Piece Integrity
The second reason is collation integrity. While all document feeders have dou-
ble detection sensors to detect double feeds, the combination of paper skew,
and other variables could result in the system occasionally missing a single
End-of-Collation (EOC) mark, allowing two full collations to be mailed as one.
The addition of bench mark (BM), beginning-of-collation (BOC), parity, and
safety marks provide additional integrity on both the scanning operation, and
on the overall collation integrity. Consequently, a combination of various scan
marks (with their associated functionality) creates a high integrity level, mak-
ing it practically impossible to have two statements inserted in one envelope.
Handle Complex Jobs Reliably
For some applications, collation integrity implies much more than just handling
variable sheet collations.
There are scan code functions that provide the ability to personalize inserts
added to a mailing by dynamically select feeding them from any downstream
feeders in the system. The application can be as simple as adding an overdue
notice to all customers whose bill is late, or as complex as customizing up to
five inserts.
Other scan code functions provide the ability to run matched mail applications
where two or more print streams are merged with assurance that the right
items are matched with the correct mail piece. This feature compares codes
printed on each document to verify the match. You can also print sequential
codes (wrap-around sequence or WAS) or page numbers to provide additional
integrity.
