OMR read head In the manufacture and printing of mark documents a particular dimensional field must be exactly adhered to Besides this the clock mark track and the marking area must run exactly parallel to the edge of the document that is transported along the document stopper during the read process On documents that are printed or cut askew the clock mark track and the marking area are spread across the entire document outside of the dimensional field These deviations in dimension can be compensated within a certain tolerance range by means of a lateral shifting of the OMR scanning strip 4 1 1 Basic setting standard document The mark scanning is set at the factory to correspond to a standard document The table below shows the distances in mm based on a sample of 40 track scanning with mark spacing of 1 5 The dimensions A and H are decisive for the correct lateral setting of the OMR read head When these dimensions due to inaccurate printing or cutting of the documents are smaller or larger deviations max 1 to 3 mm compensation can be achieved by corresponding adjustment Document stopper min norm max The read head must be adjusted when marks even quite solid marks that do not fill out the entire width of the mark field are not scanned at all or are only Axiome Alpha SA 4 1 E OXIOIII scanned in an inaccurate manner It is also typical that marks are recognized although they are actually t
