Hi ehbowen,
Thank you for using the Support Forum. As far as i know the WorkCentre 6515DNI is still in production. Please take a look at the product page for locations to purchase the printer.
We're about to specify a printer for a remote office and I was planning to recommend the WorkCentre 6515DNI as it meets our projected needs and I have experience with it elsewhere. But in checking availability I saw it was out of stock everywhere I checked. Is this a supply chain glitch which will be resolved presently, or is the printer out of production and I need to look for an equivalent?
