Cleaning fluid can be used in case of exchanging ink on other kind of it.
Setup printed must be washed very carefully with the aid of cleaning fluid adequate to the old solvent ink. For instance, when you change OEM company original ink on compatible ink, first setup printed of plotter has to be washed by appropriate OEM company cleaning fluid. Then, setup printed of plotter has to be washed again by our company cleanig fluid adequate to the type of plotter and type of our compatible ink.
After these activities, you can print by compatible ink (there is a certainty, that there won't appear any chemical reaction of ink with the remains of inappropriate cleaning fluid). When the print will be finished, print head must be washed.
Sponge and head parking should be wetted by cleaning fluid all the time.
