Ask any technician that has been in the addressing industry for over 10 years and they will tell you. The Rena Imager I is the most durable and dependable desk to address printer on the market! We’ve seen Rena Imager I’s / Neopost SA50 that have printed over 12 million addresses, and still going strong. For course you will need to change feed rollers and separator tips every so often. But an experienced technician can replace both in under an hour. And have your Rena Imager I back up and running like new in no time flat!
