When the printed output shows lines with missing colours followed by a large spot, a droplet of ink blocks a number of printhead nozzles on the nozzle surface. The droplet increases until it falls off the printhead onto the media, causing a large spot.
The cause of this problem can be inadequate printhead maintenance, or the presence of paper fibres that block the printhead nozzles.
