Purchased Dell 2155cdn color printer with automatic document feeder. Sales person at Dell to whom I spoke (and my reading of the web Dell site) seemed to indicate that one could:
1. print multi-page 2-sided
2. copy multi-page, 2-sided original
3. scan multi-page, 2-sided original
Task (1) works great.
Tasks (2) and (3) do not work. One can copy/scan the first side of a multi-page original using the automatic document feeder (ADF), but the printer never prompts you to turn the originals over to capture the second side. That makes copying/scanning multi-page, 2-sided originals impossible with the ADF.
I understand that the ADF is not duplexing, i.e., it does not turn each sheet over for you. I was prepared upon purchase to manually flip a stack of originals over to capture the second side and then have the copies come out, or the scans sent to the computer. However, the printer firmware is not allowing this.
Has anyone solved this problem?
