I have euro version of p5000 and i have refillable cartridges with restable chip…some times it works and some times it doesn’t
I could easly rest the oem chips but when i pull it off in put it in the refelable it dosent work
I check and find 2 springs under it …what they are do and how i use the oems plz check photos
The chip contact is going to an air-gap sensor. I can’t tell you more but it’s probably to-do with the contact on those two wires at the bottom.
