PROBLEM TO BE SOLVED: To automate all processes including a test printing process with simple constitution.SOLUTION: A cleaning unit comprises: a first roller which delivers and takes up cleaning paper; a second roller which takes up the cleaning paper as much as the cleaning paper is delivered when delivered by the first roller; and delivers the cleaning paper as much as the cleaning paper is taken up when taken up by the first roller; and a nozzle which is provided between the first roller and second roller. Test printing is carried out by: moving the cleaning unit to a metal mask side; making the nozzle abut on a squeeze with the cleaning paper and metal mask interposed; then interlocking the cleaning unit with the squeeze moving on the metal mask so as to hold the nozzle and squeeze in the abutting state; and delivering and taking up the cleaning paper by driving and rotating the first roller and second roller such that the cleaning paper is stationary relative to the metal mask.SELECTED DRAWING: Figure 1 |
