1-2 Before Starting Operations
*If equipped with both Metallic Silver ink and White ink, Lk (Light Black) ink is not used. Ignore
"Lk" in this manual.
Important: Characteristics of Inks and Important Notes
The usage and handling of white ink and metallic silver ink involve some important considerations that do not
apply to ink of other colors. Be sure to familiarize yourself with the characteristics of the inks before you use them.
White Ink and Metallic Silver Ink Precipitate.
If they are allowed to stand, the precipitates in them may solidify and cause clogging of the print heads or
other malfunction. Be sure to observe the cautions in this manual.
Maintenance Must be Performed.
Always keep the main power switched on. If the main power is switched o, the automatic maintenance
function stops working, and it may result in malfunction.
We recommend that you operate the printer at least once a week.
If the printer is left unused for a long period of time, ink precipitation may occur, causing unstable ink
discharge, which may result in dot drop-out, etc. In such cases, the precipitated and solidied ink needs
to be cleared.
P. 62, "When Dot Drop-out Etc. Cannot be Corrected"
Drying Inks
After output, allow the ink to dry suciently. Note that white ink and metallic silver ink in particular require
printing at a high density, and so are more dicult to dry than CMYKLcLMLk inks.
We recommend to use an optional dryer.
P. 7, "Precautions When Using an Optional Dryer"
We Strongly Recommend Lamination.
Depending on conditions, the weatherability of metallic silver ink and white ink may be inferior to that of
CMYKLcLmLk inks. Therefore, laminating is strongly recommended.
