Reprographic Systems

Market Segment Discussion

 Reprographic Systems refers to copiers and printers and covers the range from inexpensive $300 LaserJet printers to million dollar plus sophisticated, high speed color printing systems. 

 Systems utilizing magnetic toner require precision toner roll transfer assemblies. These may be individual rolls with multiple pole magnetic patterns or, in larger systems, rolls comprised of numerous magnets separated by filler material. 

 Magnetic materials utilized in these transfer rolls include: 

•  Injection molded ferrite 
•  Extruded ferrite 
•  Sintered neodymium-iron-boron 
•  Compression bonded neodymium-iron-boron
   

 Magnetic toner copier and printing systems are widely utilized by everyone from the casual PC user to the most sophisticated graphic artist to reproduction of graphics art by professional printing companies. Arnold is a major supplier into this industry, supplying injection molded magnet rolls, magnets used in assemblies and construction of the complete toner assembly modules.

Application Example

 Reprographic Toner Transfer Rolls span the range from single, injection molded components to assemblies of 100 magnets or more. 

 In all cases, the magnetic pattern is complex and must be precisely reproduced. This requires the highest quality magnets coupled with precision assembly. Arnold Magnetic Technologies Corp.has been providing precision assemblies for over 30 years. 

 Magnet materials may be high energy extruded flexible ferrite such as from Flexmag Industries or Injection Molded Neo such as from the injection molded factory of Arnold Magnetics Ltd. near Shenzhen, China.
