Printing Issues

• 1). Pull any jammed paper out of the output tray and press “Ok” if you receive a “Clear Paper Jam” message. If the jam is inside the machine, pull and hold the scanning unit lever and raise the scanning unit. Open the first inner cover, then the second inner cover and pull out any jammed paper. Close the covers and the scanning unit and press “Ok.”
  
  
• 2). Close any applications you aren’t using in case there isn’t enough memory.
  
  
• 3). Delete any files you don’t need to free up space in case the hard drive does not have enough space.
  
  
• 4). Uninstall the printer driver and reinstall it if your printer still won’t print. Close any open software applications, including virus checkers, click “Start” in the bottom left corner of your window, select “All Programs,” “Canon,” and “ScanGearStarter,” then click “Uninstall ScanGearStarter” and “Ok.” Click “Start” again, select “All Programs,” “Canon,” and “MP Drivers 6.0,” then click “Uninstall Drivers.” Select “MP780 Series” in the device to delete the box and click “Perform.” Restart your computer if prompted but remove the USB cable first.

Press “Fax,” “Image Quality” and use the left or right arrows to set a different resolution, then click “Ok.” Press “Fax,” “Exposure” and use the left arrow to decrease the contrast or the right arrow to increase the contrast, then click “Ok.”
