I'm using coneColor refillable cartidges and coneColor ink.
My Epson 9900 has been showing the ink level of the VLM cartridge going down rather quickly, while other cartridges were not showing such ink use. I was a bit mystified why more VLM ink was being used but just went with it. When it showed that it needed replacing, I took it out found that it was quite full. I reset the chip and put it back in the printer and it now registers full.
I asked epson and they said to clean the contacts on the chip, which I haven't done, as I had already reinserted it when I talked to them and it was now reading full after the reset.
Any idea why this happened?
