ReTIMe MARKs

Retime Marks are necessary for reliable reading of the code, due to the paper speed varying as it
feeds. With Basic OMR only the first Retiming mark is needed, if one or both of the other groups are
used the Retime Mark associated with that group(s) must also be printed. Retime Marks must be
print on every sheet with in the prime set.
NOTes:
The beginning sheet of a set is defined as the first to be picked up and fed. This
is always the last logical page of a document, whether reverse-collated in Sheet Feeder 1 or
forward-collated but face down in Sheet Feeder 2. Similarly, the end sheet of a set is defined
as the last to be picked up and will always be the address sheet.
After clearing the deck and before continuing the run, the user has only to complete the cur-
rent set manually and to ensure that the top sheet in the OMR sheet feeder is the last one of
the next set to be processed.
