Printed results are coarse or contain horizontal stripes

Do the Print Heads Show Nozzle Drop-Out?

Carry out a printing test and make sure no nozzle drop-out occurs. If nozzle drop-out is present, perform head cleaning according to the following procedure. Because there are cleaning procedures that use a lot of ink, perform a Nozzle Drop-out Test after each procedure to check whether the situation has improved.
  1. Perform Normal Cleaning.
  2. Perform Medium Cleaning.
  3. Perform Powerful Cleaning.
  4. Perform Start-up cleaning.
MEMO If severe dot drop-out—such as dot drop-out in multiple locations within a row—occurs, see Handling Severe Dot Drop-out.

Have you carried out Feed Correction?

Large misalignment in the amount of feed of the media may result in printing that seems coarse or contains horizontal bands. It is recommended to carry out Feed Correction when you change the media type.

Is the temperature of the room too low?

The heater may not warm up sufficiently when the ambient temperature is less than 20°C (68°F). Also, even when the heater warms up, adequate effectiveness may not be apparent if the media is thoroughly chilled. Before printing, allow the media to come to room temperature.

Is the printer installed in a level and stable location?

Never install the machine in a location where it is tilted or where it may wobble or experience vibration. Also make sure that the print heads are not exposed to moving air. These factors may lead to nozzle drop-out or reduced printing quality.

Is the printer installed in a location out of direct sunlight?

Never install in a location exposed to direct sunlight.
