I installed the VM and Cyan carts for the first time in my 3880 today and the VM cart is not being recognized. I have tried all the troubleshooting steps I can find on your website and forum with no change. I can’t see any issues with the chip, plastic lugs ok, cleaned contacts, checked retractable pins, reset printer, etc. No problems when I revert to the OEM cart, so I can only assume the chip is faulty. I look fwd to your response, Cheers - Steve Winter
Followup - I have managed to get it working by binding sellotape around the cartridge and over the end of the reset chip where the contact pins are located…I can only assume that the pins are now all making contact with the OEM chip. Not ideal but it’s allowing me to print. What do you recommend?
