ブローオフ装置での測定条件の最適化

抄録

The　electro-photographic　recording　system　is　widely　used　in　copy　machines,printers　and　facsimiles.　There　are　two　important　quality　characteristics　in　the system　:　the　amount　of　toner　particle　charge　and　toner　concentration.　In　this study,　the　condition　of　the　blow-off　measurement　that　measures　these characteristics　was　optimized. The　sample　weight　is　considered　as　the　signal,　but　the　true　values　of　toner weight　and　toner　particle　charge　are　unknown.　Therefore,　the　amount　of　samples are　varied　in　such　a　way　that　the　ratios　between　samples　are　accurately　set.　The SN　ratio　is　calculated　using　the　case　when　the　signal　factor　level　ratio　intervals are　known. From　the　study,　a　significant　improvement　in　the　measuring　accuracy　for　toner charge　and　toner　weight　is　achieved.
