4. Solving Print Quality Problems
4-1-2. Heavy misfiring in printing
（
Checking Cracks inside the Tube
）
The ink may gel when the Tube kinks or twists, which will soon cover the Filter inside the Print Head, which
causes huge numbers of misfiring. With the frozen or expired ink may cause this issue. The gel is floating over
the Filter so the missing nozzles may occur only with the big print. Confirm this issue by the following
instruction steps.
1.
Place a sheet of A3-sized paper in the center of the Platen as shown in the photograph below.
As the paper absorbs ink it will curl up and contact the Print Heads. This should be prevented by
adjusting the Platen height to position “C”.
Use adhesive tape at corners and edges to make the paper flat.
2. Load the solid print pattern to the printer from the Advanced Menu. Display the Advanced Menu from the
left Operation Panel to check the color Tubes, and from the right Operation Panel to check the white
Tubes. Next select “Solid Print”, followed by “Solid_K (black)”, “Solid_M (magenta)”, “Solid_C (cyan)”,
“Solid_Y (yellow)”, or “Solid_W* (white, *: 1 to 4)”. By pressing the OK button, the solid print pattern is
loaded and “Ready” appears on the display. (The example shown below is for a black pattern.)
Example: Solid K (Black pattern)
