![]() ![]() If you are lucky, gravity and the cleaner will help dissolve the old ink. Pour a small amount of cleaner in the barrel and let it sit for a couple of days. Worst case, if you don't have an untrasonic cleaner, the piston-filler mechanism can be removed, stand the pen in a tall narrow container (I use a juice glass) with a bit of cleaner in the bottom. The cleaning solution is Rapid-o-eze, and is often available at art supply and hobby stores (Michael's used to carry it, not sure if they still do). Many of these were used with an ink that is not water soluble and may need a special solution, and possibly an ultrasonic cleaner, to clean. ![]() If the pen was not cleaned before being put away, the piston may not move or, the tip may be plugged with old ink and fail to draw. When the fill knob stops, in either direction, do not force it. Remove the blind cap to expose a knurled knob the knob turns counter-clockwise to evacuate the barrel, emerse the tip in ink or water and turn the knob clockwise to fill. If it is like the few that have come into my hands over the years, it is a piston filler. So what do I need to do? Would appreciate help getting this thing on the road. It doesn't seem to pull out and I don't want to force anything. But then I can't see what is supposed to happen. Removing the end of the pen (opposite the point), there is knurled nob that screws out. It looks more like a fountain pen than some pictures I have seen here. Using the Koh-I-Noor Cleaner frequently on your drawing points will keep them in top working condition. It can also be used as an in-flow starter for plotter points. This cleaner uses only squeeze-pressure, and no aerosol propellants. #KOH I NOOR RAPID SKETCH INK PENS HOW TO#We are extremely proud to have participated in the reunification of this prestigious brand.Hi-I am having some trouble figuring out how to use a Rapidograph technical fountain pen that just arrived today. The Koh-I-Noor Pen Cleaner is an extremely effective device for cleaning all Koh-I-Noor drawing points. The Koh-I-Noor line of drawing pencils has expanded from the classic graphite pencil to over 20 degrees of graphite, colored and aquarelle pencils, pastels, blocks, watercolors, and a plethora of drawing accessories. #KOH I NOOR RAPID SKETCH INK PENS PROFESSIONAL#Roth, president of Chartpak Inc., acquired Koh-I-Noor North America - famous for its world-renowned Rapidograph® Technical pens which are made in our plants in the United States, and partnered once again with Koh-I-Noor Europe and the Breeza family to bring a cohesive line of professional drawing materials to the USA, Canada and South America. Meanwhile, Koh-I-Noor USA had developed some of the finest technical drawing supplies on the market. Over time, the two companies developed different art materials - Koh-I-Noor Europe manufactured fine art materials such as pencils and paints, along with office and school supplies. However, with World War II came the division of Koh-I-Noor North America and Koh-I-Noor Europe. The company expanded in 1890 and established a branch in Bloomsbury, New Jersey. The monarch's inspiration was the Koh-I-Noor diamond, a gift from India to add to the royal collection. In fact, one hundred years later, Hardtmuth writing instruments caught the attention of HRH Queen Victoria, who gave the Koh-I-Noor pencil its official name. A true innovator and entrepreneur, Joseph Hardtmuth invented and patented his process for blending clay, graphite powder, soot and an organic binder to produce writing and drawing instruments of the highest quality. Developed in 1790, the Hardtmuth drawing pencil was the very first of its kind. ![]()
