Ploymerized Toner

Art Post (Guest)

Just thought that I would touch on the subject of polymerized toner.

I do not believe our 2090's or 2105's use this toner technology (if I am wrong please correct me), and I do believe that our new color machines are using this new technology in toner.

It has been stated that this new toner (polymerized) fuses very hard, and the resulting copies do not mark or smear when customers use "off-line" finishing equipment, such as binders, folders, numbering, scoring machines and booklet makers. I quess this is a big plus for the Konica Minoltas high end system (the 1050).

I would hope that in the new Katana series from Ricoh they will be using thier new PXP toner (ricohs ploymerized toner).

I have added some press releases below from Tomegawa, KonicaMinolt and Ricoh for your reading.

“Konica Minolta is very honored to be a recipient of BERTL’s 2005 Reader’s Choice Awards, especially since they represent the voices of the End User and Reseller communities,” said William H. Brewster, Jr., vice president, marketing, Konica Minolta Business Solutions U.S.A., Inc. “These awards highlight our unwavering commitment to reliability and image quality. Konica Minolta has established itself as an industry leader in image quality with our Simitri® Polymerized Toner. Compared to conventional toner, Simitri Polymerized Toner provides a drastic improvement in image quality — high resolution, and excellent gradation and sharpness.”

Generally, toners are manufactured by mixing materials under heat, and then crushing and classifying them (Crushing method). With the polymerization method, the materials are mixed through a polymerization process to form toner particles.

Reducing Environmental Impact by Manufacturing P x P Toners
Ricoh developed the industry's first polyester polymerization toner (P x P toner)*, which is chemically manufactured using polyester resin materials, coloring agents, and wax to ensure higher copying/printing quality. Compared with traditional toner particles made by crushing materials, the energy (in CO2) required to manufacture P x P toner is reduced approximately 35%.
Also, thanks to the uniform thermal properties obtained by the use of polyester resin, the fixing temperature can be lowered which, in turn, contributes to energy conservation while the toner is used.

* P x P toner was developed using Ricoh's unique polymerization method. P x P stands for polyester x polymerization. Traditional polymerized toner is made from styrene and acrylic resins while P x P toner contains polyester resins.

We are dual-line Ricoh and Konica; so I've heard a lot from Konica about their "Simitri" polyermized toner. I dismissed it as marketing hype.....

...but then last summer I attended the American Printer magazine's Variables conference. This was geared toward printers who do variable data printing, and I went because our dealership wanted to better understand the issues that printers face as we get more into that market (we sell the 1050 and variable data software).

In the middle of the finishing discussion, an objective source, one of the keynote speakers, sang the praises of the Konica Simitri toner to the room. He was referring to jobs he did on a color 8050, and he LOVED the toner because it didn't smear and because he didn't have to apply a UV coating or other finishing layer. It cut down his finishing costs and time.

(Let me tell you, after he got done speaking, all of the hot-shot big iron press vendors gave this one lonely copier dealer rep a pretty chilly cold shoulder the rest of the conference!! But, a couple other attendees told me that they found it very enlightening to have a copier dealer there, and as a result they would start looking at digital copiers as affordable alternatives to smaller press runs. I guess I could stand the chill from the press reps!)
