Do you print ink dots on a highly

Also, combine the color multiple pass printing with
the printing. "8-1. Setting the print
direction >>P.229"

Is the platen positioned at too low
level? Adjust the height of the platen corresponding to the
print medium before using it. You can use the platen
height adjustment lever to adjust the height of platen.
As a rough indication, adjust the height so that it is
lowered by one step from the limit height detected by
the obstacle sensor, and check that the platen is not
detected by the sensor. "6-5. Placing print medium
in position >>P.148"
Is the firing timing well-timed? Adjust the ejection timing again. It is likely that the
setup value is incorrectly set after replacing a print
head or the platen with a new one, or after adjusting
the platen height. "7-4-3. Firing adjustment
