Greetings ,
This issue is typically caused by a clogged printhead or nozzles. Misaligned printhead can also cause blank lines or streaks in printed text.
Sometimes it can take several cleanings to resolve this issue, and depending on the clog you can waste a lot of money on inks trying to solve the problem.
