I have a HP Officejet Pro 8500 Wireless. The error message: Carriage Jam will not clear even after opening the print-carriage access door, seeing there is no jam and then pressing OK to continue. It tries to reset and then reissues the same error message
If the error persists, I'm afraid the printer hardware has gone bad. It could be the sensors. Please reach out to the HP Support in your region regarding the service options for your printer.
If the printer is out of warranty, I suggest you upgrade the printer. You may visit Hp Store to check the available printers.
Keep me posted for any other assistance.
