Solution #7UV is the recovery fluid for UV curable print heads: Spectra, Xaar, Konica-Minolta, Hitachi, Toshiba Tec. Works well with Sericol UV inks. This is a very effective fluid that works with a wide range of UV inks. It can unclog and straighten nozzles of your pintheads. Do not leave this solution inside a print head for more than 30 minutes. Flush the head out using the flushing solution that came with the inks that were used on that print head. If you don’t have such flush, use our recovery fluid #1X.
