Gandi 1224 Vacuum wipe...Seems too good to be true...

[Banners Signs Etc.]

So I recently discovered vacuum wipe whereby the carriage goes over a glorified vacuum cleaner attachment that sucks extra ink from priming down into a hole somewhere. (a waste tank that I do not know how to empty lol)

This seems superior to the wiping with a lint free towel method...what is the catch?

There is no catch.

The waste tank that you don't know how to empty actually drains into the larger waste tank every time you do a vacuum wipe. The catch is that ink does solidify over time in both of these waste tanks. Both of them have 2 pumps which are the same for pumping ink from your bulk tank into your reservoirs.

The main catch is tweaking the speed and suction so that is actually works properly and doesn't wipe each colour ink to the neighboring colours.

I'd be happy to help with more details.
