I checked with K.Bancha, he said Fuji can fix the problems we had and it works, but we tested with the metal net tray and sterilizing tray, the metal net tray is better, so we want to ask Fuji to replace the metal net tray instead of sterilizing tray in the standard set we order.
This is in the part of the unit that no need to make the CFS.
Even Fuji informed that, we cannot put all instrument full in the tray, but in reality customers always do like that, so if we change to metal tray net is better.
