https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/scanner-in-use/m-p/153944#M40645 <P>I use Canon MP258 with Macbook Air (OS X ElCapitan), but sometimes I cannot scan because of this error message: "cannot scan while it is being used &nbsp;by another user or application." I tried to reboot/unplug my printer and restart my computer, but it didn't solve my problem. It also happened before I update my OS. Please help!</P> Wed, 14 Oct 2015 05:45:31 GMT elizabethsandra 2015-10-14T05:45:31Z https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/scanner-in-use/m-p/153944#M40645 <P>I use Canon MP258 with Macbook Air (OS X ElCapitan), but sometimes I cannot scan because of this error message: "cannot scan while it is being used &nbsp;by another user or application."
