The author outlined a model to examine unexpected breakdowns in modern printing machines. He was analyzing the different downtimes for years. The results of the researches help to organize the pro-active maintenance at the graphic arts industry.

During the study, the operation of characteristic printing machines was monitored in two steps, primarily to analyze unexpected breakdowns. From 1988 until 2004, i.e. for 17 years a database of unexpected breakdowns was structured with respect to 65 modern printing machines. The associated theoretical and practical conclusions drawn from the study were presented in 2008, in Valencia (Spain) at the 35th IARIGAI (International Association of Research Organizations for the Information) Conference. This publication is a summary of the observations of an additional period of 10 years (2005-2014). In this latter period, 71 mechanical printing equipment units were studied; some of them were identical to the machines investigated earlier, but a significant part of them were newly commissioned machines. Resulting from the study, the database of unexpected breakdowns was compared to the earlier results to highlight similarities, changes and development. One of the major conclusions of the study that is reflected from the results of the full-scale (27-year) monitoring effort is that in the world of printing machines a large proportion of unexpected breakdown, failures are technical or technological errors that can be quickly tackled.
