Oh no, that’s frustrating! It sounds like your printer is detecting that the cover isn’t properly closed, which is why it’s throwing that error. I’d recommend checking with the manufacturer’s website first they often sell replacement parts like ink cartridge covers. If you can’t find it there, you might want to try looking on eBay or Amazon, where people sometimes sell used or refurbished parts. You could also reach out to the manufacturer’s customer service to see if they can point you in the right direction or even provide the part directly. Good luck, and I hope you can get your printer up and running again soon!
