Retiming Mark
This mark is mandatory in each group of OMR marks making up the
code (see later in this section for an explanation of OMR mark group-
ing).
It allows the machine to recalibrate for accurate scanning. Retiming
marks count in the parity calculation.
Select Feed (SF1, SF2)
These marks are used to control the feed of material from the feeder
holding the supplementary sheets/inserts on a set-by-set basis.
Therefore you cannot use select feed on a single-station machine.
Use
Select Feed 1 marks are in the primary sheet feeder to select
material from the supplementary sheet feeder. For C- and double
fold, the primary feeder is sheet feeder 1. For Z- and single fold, the
primary feeder is sheet feeder 2.
Use
Select Feed 2 marks in the primary sheet feeder to select mate-
rial from the insert feeder. For C- and double fold, the primary feeder
is sheet feeder 1. For Z- and single fold, the primary feeder is sheet
feeder 2.
Auto Batch
This mark identifies the last set of a batch, when the batch function is
in use. It must appear on all sheets of the OMR set that requests this
function.
Wrap Around Sequence (WAS1, WAS2, WAS3)
This is a numbering system which uses a sequential binary coding. If
a page is missing or the set goes out of sequential order, the system
stops processing and declares an error.
Three wrap around sequence marks are used within the code. The
use of three binary digits allows a decimal count of 0 to 7. Pages are
numbered from 0 up to 7, and then back to 0 on a continuous cycle
throughout the print run.
