When Dot Drop-Out Cannot Be Cleared Up

In this operation, all white and gloss inks within the printer are discharged, and the interior is cleaned. Ink is
refilled after cleaning. This operation requires two SOL INK cleaning cartridges.
" If you want to perform maintenance on inks other than white or gloss ink, see "Cleaning All Print Heads"
(p. 44).
MEMO
White ink tends to settle, and may harden if allowed to stand for a lengthy time. Therefore, abnormal ink
emission including dot drop-out tends to occur more frequently than with other inks, even when using the
cleaning function (Normal, Medium, or Powerful) or manual cleaning.
NOTE
Be sure to hold the handle of the front cover, open and close it gently.
Important Notes on This Procedure
• A large amount of ink will be discharged during this operation. Perform this operation when all procedures
such as "Normal, " "Medium, " "Powerful, " and "Manual" cleaning, and measures to improve ink emission flaws
(such as dot drop-out) do not improve the symptoms.

" "Medium and Powerful Cleaning" (p. 33)
" "Manual Cleaning" (p. 35)
• Be sure to use SOL INK cleaning cartridges. Use of any other type may result in breakdown.
• According to the procedure, fill with ink as soon as possible. Allowing the machine to stand without ink
may damage the print heads.
