UDATE: My hands are stained red from Piezoflush, and I look like I am either a butcher or a mass murderer. Basically I overflowed my maintenance tank doing "Power Cleans." The 7800 has been stored with Piezoflush, and now the carts are half empty after the initial fill and all the cleaning. I printed 5 perfect nozzle checks in a row to make mucho sure I have a like new printer that is fresh.
Although the printer only cost me $100.00, the set of carts set me back about $300.00, and the gallon of Piezoflush is now half gone which also cost about $300.00. Had a bit of an emergency with the overflow from the printer. It was like the 7800 was hemorrhaging. Then the setback was I had no spare maintenance cart, and with today being Saturday B&H is closed. I also ran out of rubber gloves.
I ended up dissembling the maintenance cart and washing out the absorbent material. Because it was soaked with Piezoflush I was able to get the media really clean. Piezoflush dissolved the dried ink. What a mess in my kitchen sink. Glad that Maggie didn't see what I was doing. LOL.
So now I'm downloaded paper profiles that I have to zip-install into my "Print-Tool." If everything goes right I'll load the carts I filled last night. 700 ml bottles of ink cost about $200.00 each. Multiply $200.00 times 7 shades of black, and in two more shades of black because I blend inks in shades 3&4, and then add in three bottles of Gloss Overcoat and I have $2400.00 worth of ink and I used about half of it to fill the carts. I expect loosing about a third of the ink just doing the initial fill and perhaps a few more cleaning cycles.
Last night I grew cross-eyed loading the carts. What is really scary is that I no longer use a syringe to load my carts: I use a funnel and pour from a bottle. What made things tedious is that I have the supply of ink leftover from my 3880, so I had to be thoughtful not to screw anything up. Pretty easy to do when you are tired. I wanted the air bubbles to settle overnight as not to introduce problems because at this level mistakes are very costly. I had so many empty plastic bottles that it seemed like I was cleaning up after a beer party. Anyways I condensed some of my warehouse space on the wall.
Anyways I learned of yet more things to try in making a better print. It seems I data mined out that I can lay down more ink by using curves/profiles that are for larger printers that were designed for K-3 ink sets, but I might have to also increase the amount of Gloss Overcoat required to eliminate Bronzing and Gloss Differential. I would expect a more 3-D effect with more ink on the paper. Hmmm.
Anyways, if everything goes well I might be printing later tonight or tomorrow.
