摘要： A determining unit determines whether the printer is in the predictive failure state based on the internal information of the printer acquired by the information acquiring unit. A failure risk computing unit performs a failure risk determination process for determining the size of failure risk of the printer when the printer is in the predictive failure state. The determination result is reported to a maintenance person or a user. In this way, the maintenance person or the user who receives the report can definitely grasp a degree of urgency of maintenance at that point.

摘要： An extension piece portion is provided at a lower end portion of a screen plate so as to extend from the lower end portion, beyond a gas-passing through hole, to an oil pocket portion. An oil guide portion is provided at respective gas-hitting-side face portions of the screen plate and the extension piece portion so as to guide oil trapped at the above-described face portions into the oil pocket portion. Accordingly, it can be prevented that part of the oil in the middle of dropping down into the oil pocket portion from the screen plate is carried away by the gas flow passing through the gas-passing through hole, so that the efficiency of oil trap can be improved.
