Basically what that means is that it is cheaper for us to replace a printer than to send somebody out to fix it. So unless we can get it running over the phone with the end user, we ship the new printers out to them with a return label. The older printers come back and we either fix them in-house and put them on the shelf (to send to somebody else)) or we trash them.
Things have come a long ways from the old days when a technician was scheduled to service the copy machine that cost half as much as a new car every month, or in some cases every week...
My wife remembers working as a department head at several places where she thought that the outside copy machine technician was part of the staff and he came to the Christmas parties etc... She said she was always surprised when someone would tell her, "No, he is not an employee, he is just here all the time keeping the copying machine working." Times have changed.
