Make sure that driver witha name corresponding to your machine's name is listed in the window.Ensure the port is not busy. Since functional components of machine (printer and scanner) sharethe same I/O interface (port), the situation of simultaneous access of different user applicationsto the same port is possible. To avoid possible conflicts, only one of them at a time is allowed togain control over the device. The other user will encounter “device busy” response. This usuallyhappens when starting a scan procedure. An appropriate message box appears.To identify the source of the problem, open the Ports configuration and select the port assignedto your scanner, port's symbol /dev/mfp0 corresponds to LP:0 designation displayed in thescanners’ options, /dev/mfp1 relates to LP:1, and so on. USB ports start at /dev/mfp4, soscanner on USB:0 relates to /dev/mfp4 respectively and so forth sequentially. In the Selectedport pane, you can see if the port is occupied by another application. If this is the case, youshould either wait for completion of the current job or press the Release port button, if you aresure that the present port application is not functioning properly.Themachinedoes notscan.Ensure a document is loaded into the machine, ensure your machine is connected to thecomputer.If there is an I/O error while scanning.Refer to Linux User’s Guide that came with your computer for further information on Linux error messages.Common Macintosh problemscondition Suggested solutionsThe machine does not print PDF files correctly.Some parts of graphics, text, or illustrations aremissing.Printing the PDF file as an image may enable the file to print.Turn on Print As Image from the Acrobat printing options.It will take longer to print when you print a PDF file as animage.The document has printed, but the print job hasnot disappeared from the spooler in Mac OS X10.3.2.Update your Mac OS to Mac OS X 10.3.3. or higher.Some letters are not displayed normally duringthe cover page printing.Mac OS cannot create the font during the cover page printing.The English alphabet and numbers are displayed normally on thecover page.When printing a document in Mac OS withAcrobat Reader 6.0 or higher, colors printincorrectly.Make sure that the resolution setting in your machine drivermatches the one in Acrobat® Reader®.Refer to Macintosh User’s Guide that came with your computer for further information on Macintosh errormessages.
