I am having problems with my LC chip in my Epson SP 4900 printer. The cart chip is throwing an “Ink Cartridge Error Please Install the Correct ink Cartridge.” The chip first gave this error after about twenty prints and progressively became worse and is now throwing the error every one to five prints.
I requested, and was quickly sent , replacement chips (the LLK chip was independently throwing errors in the exact same way but the replacement chip now seems to be functioning just fine) and the new chip gives the exact same error EVERY single reset, I can not get one single print from the replacement chip.
I also tried a battery powered chip from an older ink cartridge set that I use exclusively for cleaning and it works perfectly without ever giving any errors. The Epson OEM cart also works perfectly. I browsed the technical website and FAQ’s sections and did not see my problem listed. I did, however, check the pins inside the printer and found none of the pins bent or misaligned, I also cleaned the pins and chip contacts with alcohol to no avail. I also tried to wedge the cart one way or the other but this did not cure the error messages.
Since beginning this customer service request I am now also getting periodic errors with the Orange and LK carts, these were usually in conjunction with the LC error and may be related.
