							Print Results Are Unsatisfactory
If the print results are unsatisfactory due to white streaks, misaligned lines, or uneven colors, check thepaper and print quality settings first.

If these settings do not match, it is not possible to obtain the proper result. If you are printing a photograph or an illustration, an incorrect paper type setting may reduce the quality of the
printout color.
Also, if you print with an incorrect paper type setting, the printed surface may be scratched.
In borderless printing, uneven coloring may occur depending on the combination of the paper type setting and
the loaded paper.
The method for checking the paper and print quality settings differs depending on what you are using your machine for.
