Is Media Reflective Intensity set to Low?

If Media Reflective Intensity is set to Low, change it to High. Changing this setting to High will increase the number of cleaning operations, preventing dot drop-out and dot displacement.
MEMO

Setting Media Reflective Intensity to Low decreases the number of cleaning operations, reducing ink consumption.

However, the risk of dot drop-out and dot displacement will be higher than when High is selected. Change this setting as needed only when setting up a print object with a thickness of 2 mm (0.07 in.) or less.

Default setting: High
