When The Dot Drop-Out Cannot Be Cleared - Roland VersaUV LEJ-640 User Manual

The Concentration and Dot Drop-Out of the White Ink

When the Dot Drop-Out Cannot be Cleared

White ink may sometimes cause abnormal discharges including the dot drop-out even when the cleaning
features (such as the normal, medium, and powerful cleaning) and the manual cleaning are performed. This
can occur because the ingredients in white ink tend to settle, and may harden if allowed to stand for a lengthy
time. If this happens, carry out the operations described below. This operation requires two cleaning cartridges.
A large amount of ink will be discharged during this operation. Perform this operation only when dot
drop-out cannot be cleared up even after performing cleaning using the cleaning function (normal,
medium, or powerful) or manual cleaning.
