When Uneven Color Issues Occur with White Ink

Damper Cleaning Method

If uneven color issues with white ink are not resolved even after shaking the pouch trays to mix the ink, perform
"damper cleaning." Uneven colors refers to the symptom of printed colors being uneven (such as the color density
being inconsistent) even when the same data is printed with the same settings.
Damper cleaning can be used to stabilize the printed colors by agitating the ink.
IMPORTANT
• Damper cleaning consumes a lot of ink, and overly frequent use may damage the print heads themselves. Avoid performing this
operation more than necessary.
• When you perform damper cleaning, replace the Lc, Lm, Lk, Or, Gr, and Wh inks with new ink pouches. If the ink runs out during
cleaning, a "CLEANING ERROR" will occur and cleaning will stop.
P. 194 ""CLEANING ERROR""
• The ink pouch that you have removed can still be used in operations other than damper cleaning (such as printing).
