SUGGESTIONS
Clean the print head. (See Cleaning the print head on page 13-12.) If
you clean the print heads five times and the print has not improved, call
Brother or your dealer for service.
Make sure the Brother TWAIN driver is selected as the primary source.
In PaperPort, click Scan in the File menu and select the Brother TWAIN
driver.
Check that the paper size setting in the application and in the printer
driver are the same.
Try setting the Display setting to '256 colours'.
Try to reduce the print resolution.
1. Open the 'Basic' tab in the printer driver.
2. Click 'Setting' in the Basic tab of the printer driver.
3. Turn OFF 'Bi-Directional Printing' by un-checking it.
