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.

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.

Have you carried out Media Gap Adjustment?

If you are performing bidirectional printing, it is recommended to carry out Media Gap Adjustment when you change the media type. The optimal adjustment value may vary depending mainly on the thickness of the media.

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 media heating system at a suitable temperature?

If the ink forms lumps or smudges, set the heater to a higher temperature.

Note, however, that a heater temperature that is too high may degrade the media or cause it to wrinkle.

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

Never install in a location exposed to direct sunlight.

Is the media loaded and set up correctly?

If the media is not loaded correctly, printing may be adversely affected. Make sure the media is loaded and set up correctly.
