My M20i somehow started ignoring the ADF. The printer detects when I insert the originals into he ADF (beeps and powers on), but then scans from empty glass when copying. Note: It also happens when faxing, so it seems not to be a copy setting which disables the feeder as described in the FAQs of another printer type.
How does the printer decide which to use? Is this a known problem?
Thanks in advance
