I pushed all the buttons and most of them work as they should. There's one all the way to the right hand side middle row that savs 1/2 s when I push this lever it only retracts partially it may need some oil to make this work properlv. I also noticed via pictures there may be a potential crack on the slide area but I can't tell if it's supposed to be that way or not. This is being sold as parts as I do not know anything about this unit. Please also note that the ink ribbon will also need to be replaced. Please leave your name and number.
