This set of 6-pages of hand-written notes is included for the sake of WLC/MRC Engineering archival completeness, more than other reasons. The topics are related to OMR reading issues, such as inks, pencils, printing, and other critical parameters, such as student 'doodles', humidity factors, controlling the incidence level of paper jams, etc. All worthy topics to present to initiates to the world of OMR, but not presented in a very legible format
