If this is really true why other types of CIS won't have the same issue because of the property of pigment based ink? This is quite technical, not just plain English. All CIS systems have problems. It may be true the pigment based ink makes it ever harder to work. The Mariotte principle seems to be a better way to build CIS on. I believe All Epson ink cartridges are designed based on principles similar to Marriotte's Bottle. The goal is to deliver a constant ink flow.The Hat said:In plain English so it is easy to understand and no technical stuff.aaa said:Hat, can you explain why pigment ink clogs Mariotte CISS?
Pigment ink is tiny solid colour particles that are kept suspended in its own solution when in constant use
but if left idle for long periods these same particles will separate then sink to the bottom and settle there.
If used in a CISS like your Mariotte system then the outlet and tubing on this system will eventually fill with this solid material
which in time will prevent the proper flow of ink to the print head, if left unchecked will lead to total head failure (Canon printer).
Now if you have the time and patience to constantly and regularly stir or shake both the bottles and the tubing
even the printer itself then this type of CISS system will probably work but for how long who knows..
