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.
