I've used an HP authorized service provider to repair my printer when, because of a defect, the cartridge lock broke. After the tech replaced it, black will not print. She took the printer apart again and re-did her work to make sure she didn't miss any steps. Again, no black when printing. We've tried several different cartridges so we've rules that out. She called HP and they said they're "not sure what else to do".
Any one have any experience with this and/or a solution? Also, what do you do with a $750.00 faulty printer when HP won't acknowledge they've sold me a printer with a defect?
