• Position of the code on the document

     And B OMR Mark specification diagram

    Minimum line thickness of a mark: 0.2 mm (0.008 inch).

    Default the first mark from the top is set to: 100 mm (3.9 inch). This parameter is set in the job settings. 

    The code must have a consistent number of marks on every page.

    The white area in the picture shows the limits where the code can be printed.

  • OMR license types

    There are two OMR license types:

    • Basic
    • Advanced
  • OMR basic license

    For the OMR basic license the following functions are available:

    • Start mark: indicates the start of the code.
    • Insert/Accumulate: defines when a document set is complete and must be inserted into an envelope.
    • Parity check: by adding a parity mark the reading code can be checked. The sum of the marks must be even.¬
    • Safety Mark: is used as an extra security (only 1-track OMR). With skewed paper the reading head can miss part of the reading code. In these situations the safety mark is not read, and the system will give an error. The safety mark also indicates the end of the reading code. This mark must always be present on the document if it is part of the code definition.

    The minimum code is one mark in one line (insert). However for reliability it is advised to use at least 2 marks. The first line is the start mark. A mark printed on the second line means insert. No mark on the second line means accumulate.

  • OMR advanced license

    For the OMR advanced license the following functions are available:

    • The basic functions (Start, Insert, Parity, Safety).
    • Divert (Divert & Continue) - The set will be diverted and the system continues.
    • Stop (Divert & Stop) - The set will be diverted and the system stops indicating error (FT1-RE1-000 Reading stop - Stop mark read).
    • Selective Feed (feeder 1-6 and the versaFeeder) - If the system reads the command, an enclosure from the enclosure feeder is added to the set. This function is printed on the last sheet of a set. 
    • Exit control - Determines if the envelope is transported to stacker or to the side exit.
    • Present on deck - The set leaves the system from the upper unit. The system does not stop processing. The envelope is not sealed.
    • Present on deck and stop - The set leaves the system from the upper unit. The system stops. The envelope is not sealed.
    • Sealing control - Determines if envelopes are sealed or not. If a mark is printed, the envelope is not sealed.
    • Sequence Check - Sheets in a stack can accidentally get out of sequence or can be missing. This can be detected by the sequence check. Each sheet has a binary code that is a part of the reading code. Depending on the application one, two or three marks are used by sequence check.
  • OMR general remarks

    General remarks:

    • In case of OMR the marks must always be used in the sequence as shown in the figure.

      OMR mark order DS-90
    • If a function is suppressed the following function will move upwards one line.
    • The mark definition is a service setting.¬
  • An Example of OMR Code

    In the figure the legend for the following example is shown. In this example, a set of 8 sheets with one selective feed and three sequence check marks is shown.

    • The first position is used for the start mark which must be printed on every sheet.
    • The second mark position is used for the insert/accumulate command.¬†A printed mark means insert, no mark means accumulate. Therefore the mark is printed on the last sheet of the set.
    • Position 3 is reserved for selective feed from the enclosure feeder. Print a mark on position 3 when a selective feed from the enclosure¬†feeder¬†is required. The marks are printed on the last sheet of the set.
    • Position 4,¬†5 and¬†6 are used for the sequence check marks. In this case a three mark sequence check is used.
