The waste bottle assembly spare part has been modified in order to increase the longevity of the ink tap. Over time UV inks may affect the current existing tap. Furthermore, strong environmental light may block the tap as well.
The new spare part assembly has a black tube with the tap on the outer end. The tap can then properly be positioned mounted vertically and light-tight in a small box in order to avoid to get in contact with environmental light and as well decrease the chance of leaking ink on the floor.
Therefore new part numbers have been introduced.
The modification is already implemented on the following VJ-1638UH & VJ-1638UR units with these serial numbers
| VJ-1638UH | ID6U001021 or higher |
| VJ-1638UH MKII | JV6U091021 or higher |
| VJ-1638UR | IU6U000180 or higher |
| VJ-1638UR MKII | JU6U090180 or higher |
... use the DG-49081 - "Waste Ink Bottle B Kit" as spare part.
The box to store the tap should already be pre-mounted on these units.
