Had the printer scanner fax about 2 weeks. When set up initially worked fine. Now when I try to scan from the adf, sometimes it scans 2 sided but I put in 12 pages, it will only scan 8. The last 2 days, it will only scan the first page even on one sided. Sometimes the pdf file is saved on the computer, other times, the scanner looks like it is scanning (feeding the pages through) but the file never gets saved to the computer. The printer is set up totally wirelessly and is able to see the computer through the network.\n\nI am at a loss of what to do, it probably is a setting but I wanted to check with others first before either uninstalling and reinstalling or returning the printer.
