thanks for your reply. I believe you are referring to shaking the white inks? Sorry I should have been specific, but I was asking about the shaking of the dampers...

please advise, thank you!

when you print, the movement of the print head will agitate the ink in the dampers a little bit. i just print white blocks of ink until the unmixed ink is gone and pure white is what is printing. if you are printing with white ink every day, then this won't be necessary. it all depends on how much time has passed between white ink prints. overnight won't be a problem. a day or more, and you will have some settling of the white ink.

So the TiO2 slowly settles out of suspension in the ink... I assume that stuff sort of "piles up" like super fine sand in the damper right? If that happens too much, I can only guess the damper must just clog up. Can that TiO2 sludge get beyond the damper and clog the nozzles?

it's possible, but not too likely if you maintain the dampers properly. i wrote a thread in the NeoFlex section regarding damper maintenance. i change out my 4 white ink dampers every 3-4 weeks.

Interesting, do you just toss the old ones even if they are still functioning?

my understanding is that yes you do.... they are what is considered a consumable and should be replaced... just like the tip in the viper one and the wiper blade....

no, no, no! i have written a thread in the NeoFlex section that details how i clean my dampers. i've had the same 4 backup dampers for white ink for about 2 years, and i rotate them out every 3-4 weeks. they are cleaned with Windex w/ammonia, then flushed with distilled water before they are put back into the printer. i will leave them soaking in Windex for a couple of weeks before flushing them out with water.

it is correct that the wiper blade and dampers are consumables, but you don't need to throw them away. they can both be cleaned. i have one extra wiper blade that i swap out while i'm cleaning the dirty blade.

also, my understanding is that the Viper One tip can also be cleaned. i do not have a Viper One, so you might check with Brian Walker on that.

The wiper blade will eventually need to be replaced regardless of how much you clean it. Kinda like the wipers on your car, they will degrade with use. For $10 it's worth having an extra one laying around. The ViperOne tips will wear out with use also, I usually keep a couple extra tips around just in case.

Having an extra set of dampers to swap out every so often is good insurance. Following Sean's guide on cleaning out the dampers is good way to save them and keep your consumable costs down. That said, sometimes the plastic valving inside the damper can fail regardless of how it's cleaned. This is more prominent with chinese dampers and not OEM Epson versions as the Epson dampers are built much much better.

Lost a white channel the other day. Tossed that damper into Windex+ammonia, pulled an old damper out of the mix, ran distilled through it a few times, and off we went. No big deal. Excellent post by @23spiderman that we now use as part of our "why is this channel dead" maintenance.

We still do an F4 about every 2 weeks, though. Just seems to help keep nozzles clean.

Haven't waterfalled yet -- with our old Easy T we had to waterfall every week.
