I have an Epson 4900 and this is my first time to use ConeColor inks. I purchased 4 sets last week - the Cyan, LVM, VM and LK. Yesterday I installed all four carts and three of them were fine, went in easily, no error messages. However, when I did the nozzle check, after installing all four, I got the error message “Ink Cartridge Error. Replace ink cartridge(s)”. The red “x” indicated it was on the LK cartridge. I also noticed that particular cart was a little “snug” when inserted, and doesn’t pop out when pushed quite as easily as the others, though this may be unrelated
After reading all related posts here, I went through the procedures suggested by your techs, including resetting the chip, “wiggling” the cart slightly, waiting and trying again, etc. Decided that maybe it was the battery behind the chip, so I went and purchased the 377 battery and installed as shown in the link on your website. No luck here either. I can put the old almost empty Epson cartridge back in and the error goes away, and the “Ink low” message reappears. It seems to me that it must be a problem with the chip, but if there is something else I should try, please advise.
Thanks for your help,
