I really need help on this. Long story short is with a Epson Workforce 600 wireless Printer. The problem is with the card reader. The printer and scanner work fine. I mapped the drive to z: first using printer name than had to change to ip address for it to work. Then that stopped working. Spent 2 hours on phone with Epson and they ended up sending me a new one. On the new one I mapped the card to z: and it said drive in use. Changed to y: and it worked one time then it said drives in use. This is on the new printer.Went to disk manager and it did not show any extra drives. I went to my second printer and it does the same thing. It acts like it is grabbing the drives and not letting go of them. Can anybody help?? I have no idea what is wrong and Epson is referring this case to Level 3 tech support. Thanks
