Print Results Not Satisfactory
If the print result is not satisfactory such as white streaks, misaligned lines, and
uneven colors, confirm the paper and print quality settings first.
z Check 1: Do the page size and media type settings match
the size and type of the loaded paper?
When these settings are incorrect, you cannot obtain a proper print result. If you
are printing a photograph or an illustration, incorrect paper type setting may
reduce the quality of 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.
z Check 2: Did you set the print quality setting appropriately?
Select a print quality option suitable to the paper and image for printing. If you
notice blurs or uneven colors, increase the print quality setting and try printing
again.
* When printing from a PictBridge compliant device, set the print quality setting
by using the Operation Panel on the printer. You cannot make this setting from
a PictBridge compliant device.
* You cannot change the print quality setting when printing from a wireless
communication device.
The method to confirm the paper and print quality settings differs depending on
what you do with your printer.
z Check 3: If the problem is not resolved, there may be other
causes.
