I'm in the market for a mid level office printer/scanner/copier with document feeder. I've been using an HP Officejet 7590 and Canon Pixma MP970. The Canon is a personal photo AIO so I have to scan one sheet at a time. The HP has limited document feeder capacity, is somewhat flaky about which documents it will scan without erroring out (think it might be the HP drivers/scan software). Need some some form of networking - wired or wireless. Any recommendations?
