I have an issue with my recent order SO5921. I have filled the PK and MK carts, and they are recognized by the printer. However, the VLM cart is not recognized by the printer (at least as a VLM cart). I reset the printer x 2 but there was no change — the error was just for the VLM cart. I checked the Epsom OEM chip — it is inserted correctly, the pins of the reset chip are all protruding about at the same amount and appear to contact the OEM chip. So I removed the Epson OEM chip from the IJM cart, and reinstalled it in the OEM Epson VLM cart, which was recognized as a VLM cart by the printer. My conclusion is that the reset chip on my IJM cart is bad. I am certain that the OEM chip is inseted correctly, and that the reset chip is correctly seated in the IJM chip.
If there are other solutions to this problem, please let me know.
