Do the print heads cause dot drop-out?
Carry out a printing test and make sure no dot drop-out or dot displacement occurs. If dot drop-out or dot
displacement is present, perform head cleaning.

Is the print head height appropriate?
Printing when the "HEAD HEIGHT" menu item is set to "HIGH" is coarser than when set to "LOW". Keep this
set to "LOW" except when changing it is necessary, such as when you are using thick media.

Have you carried out feed correction?
Large misalignment in the amount of feed of the media may result in printing that seems coarse or con-
tains horizontal stripes. Either make the setting in the software RIP to match the type of media you are
using, or make the setting for correction on the printer.

Have you carried out ink landing position correction "MEDIA GAP ADJ."?
The optimal adjustment value varies depending on the thickness of the media. Set an adjustment value
that is suitable for the media. When further correction is required, such as when adjustment made using
"MEDIA GAP ADJ SIMPLE SETTING" does not enhance printing, use "MEDIA GAP ADJ DETAIL SETTING" to make
the correction.

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 dot drop-out
or reduced printing quality.
