Professional grade Epson print heads are actually extremely durable. Many industrial printers printing with solvent oil based printers pretty much all use electric piezo print heads exclusively. Clogging does occur no doubt about it. I have seen one such printer in development phase designed for...

Another important aspect of formulating thermal bubblejet ink is in adjusting the ink's boiling point temperature. It has to be higher than a threshold point or the ink will simply clog the print head. Home brewing ink trying to adjust colors can be harmful to the print head if the boiling point...

My 2 cents... If the sponge were fully saturated with ink it would be like a piece of kitchen sponge fully soaked with water. A fully soaked sponge will drip water until a significant portion of it is emptied. You don't want that to happen to the sponge in a Canon cartridge. You will have ink...

Well said, Roy. Thanks.

I totally agree that Pro-100 is a better printer in most printing applications. If Canon's claim wasn't a hype that it used unique red and green color dyes to formulate the red and green inks for the Pro9000 then Pro-100 apparently lacks such feature. Not I really care about that but it is real...

I like that. Yes, they all eat the same thing, despite the terminology changes such as Chromalife, Chromalife100 and Chromalife100+.

Ink cartridges need a vent so that ink can flow downward for the print head to print. The vent at the top needs to be as small as possible to keep ink from drying up. A serpentine (a non engineering term but OK) is one huge step to achieve better prevention of ink drying. HP ink cartridges all...

What are the technology advances? If you can put CLI-42 chips on CLI-8 carts and use them on Pro-100 it proves by itself that the printers are essentially brothers and have a same set of genes despite they were born in different time. OK, I agree there are definitely some firmware advances...

Many of us here and many more who are not here today were there 10 years ago. All contributed to build up the knowledge base of this forum. At one point we were all beginners. You were one too... The fact is a Pro-100 with CLI-42s is not really different from pro9000 with CLI-8s. All being...

I know I did something wrong. I should have flushed with distiled drink or 100% alcohol wine. Still if I were to store a print head I would not go that way. I learned a hard lesson. Who did not back in the i960 era? I now store my print heads in the printers accompanied by all their cartridges...

I am a HP retiree. I can confirm all that... Try to look at it this way. The chip is a serial EEPROM. It can be read and written. There is nothing else there. Can't fantasize anything fancy from there. It is where the nozzle firing count is stored. The printer reads it to determine how much...

I lost two print heads by storing them, flushed, in Ziploc bags. Those print heads were clogged solid with no amount of soaking with Windex or Ammonia solution that could revive them. They were in the bag no longer than 6 months. It's not the way for storing print heads for me ever again. On...

Rite Aid Pharmacy sells a 100% Ammonia liquid in something like a quart (maybe 16 oz) bottle. It costs around $5 a bottle. They might have smaller packages.

What a resetter does to reset a chip is by writing into the chip with data that resembles empty. If the data is identical to what was in it by Canon then it does reset it to true empty. But if the data is only close to empty (to avoid a potential copyright issue) then it is only close to be...

Thanks for the info and suggestion. I do use Hobbicolors. I guess it is not long enough to conclude. I do watch every print coming out of my Pro-100. It is easy to look for the yellow on the print. Will keep watching. It's been 10 months though.
