After printing the front page, there is an ink drying wait time before starting to print the
back page (Operation stops temporarily). Do not touch the paper during this time. You
can change the ink drying wait time at Custom Settings on the Maintenance tab.
Note
If the back side of the paper becomes smudged during duplex printing, perform
Bottom Plate Cleaning in the Maintenance tab.
Unless head position adjustment is performed after an ink cartridge is loaded or
replaced, the intended print results may not be obtained during automatic duplex
printing. If the print results are not satisfactory, refer to "Aligning the Print Head Position
from Your Computer" and adjust the head position.
