27. Maintenance Maintenance concept The maintenance policy for the Oc 7050 is according to other low and mid volume machines to execute some Preventive Maintenance PM during a cor rective Maintenance CM visit We expect that the machine needs very little PM Therefore the PM which has to be done during every CM visit is very lim ited Besides this the operator will be stimulated to do operator maintenance PM executed during a CM visit includes 1 CHECK on wear and deviations During the lifetime of the machine parts will wear and adjustments will change due to use of the machine and the circumstances at the customers site To en sure proper functioning the machine must be checked every visit by means of the PM checklist 2 CLEANING of vital sections Certain areas of the machine are sensitive to dust and toner pollution The Oc 7050 has an air box inside which perfectly controls the air flow inside the ma chine and together with the seals this results in very little pollution This makes PM cleaning during every CM visit almost superfluous 3 REPLACEMENT of almost worn parts When almost worn parts are not replaced in time it can result in damaged or earlier replacement of more expensive parts in the machine before their expect ed lifetime and in additional service visits ed 6 Maintenance 3 2 Preventive Maintenance Programmes PM programme every visit original glass see Cleaning the original glass
