For all printing techniques if we want to get a good impression is very important maintain of the machine. Causes of poor impression can be very different, the advantage is that digital machines have a range of options for quality impression, with whom we maintaining regular and analysis to maintain a very high quality prints. One of these options is checking the cleanliness of the machine (Chek Engine cleanness). This is an automatic procedure to print a series of files which allow us to estimate cleanliness of the machine, and this procedure can help us to decide if you need to clean the machine, and specify which parts need to be cleaned. The option allows you to check one or both sides of the paper in all colors or just one. Analysis of cleanliness testing machine will be examined and implemented in a real manufacturing on a digital printing machine for a period of one month. The work will be carried out research in which will be seen how often is necessary to implement the maintenance and cleaning of the machine for better and more efficient execution of each task. It will also be researched how much affecting a factor the time, and how the occurrence of failure depends on the number of prints. This procedure is very essential for providing quality service that allows us a digital machine, and because the possibility of the same very wide spectrum.
