I am getting a constant error message on my V505 printer that there is an alignment problem. It tells me to remove the tape from the cartridge. I have checked the cartridges repeatedly and there is no tape on either one. I click the check mark on the printer and it prints out an alignment page and then proceeds to give the same error message. I have unplugged it. Rebooted it. I have installed firmware and driver updates. What else can I do? Thanks.
