This unit powers on, the print engine seems to work fine, and the control panel up above on the applicator works fine. I have not tested it further for a lack of fresh ink ribbon and labels. The lid and the print engine has a broken hinge so it will easily slip loose and cause a Open Cover error message. It?s missing a plastic disc for holding the label roll on the peg. I haven?t hooked it up to compressed air. The covers on the compressed air gauges are missing.
