As of January 2001 a DIN 33870 standard lays down criteria for the composition, storage, packaging and labeling of toner cartridges and toner. All toner modules supplied by K+U meet this standard. Before toner modules can satisfy DIN 33870 requirements, however, they are subjected to extensive tests and must fulfill stringent conditions. The tests begin with examinations for genetically harmful effects, toner adhesion, yield, test in climate chambers, obligatory declaration of contents and appropriate safety instructions. Each cartridge bears an identification label, so that even months later it is possible to tell when the cartridge was produced, which toner batch it is filled with and who filled it. Each cartridge has to undergo exhaustive tests. The basis for comparing test values is the results per type of five original cartridges made by the printer manufacturers. All K+U Printware cartridges comply stringently with the requirements of DIN 33870. In fact they go even further: The standards by which freecolor products are manufactured are even stricter than those of DIN 33870. freecolor products not only meet DIN 33870 quality requirements, they even exceed them. As standard practise, we refit freecolor laser cartridges with a new OPC drum and new electric contacts. These are just two examples of ways in which freecolor products go even beyond the standard requirements.Contents of DIN 33870

What does DIN 33870 regulate?
DIN 33870: Material Safety data sheet In addition to printing quality and yield, DIN 33870 also makes the environmental and health factors of remanufactured laser printer cartridges transparent to the consumer. For this reason every product produced according to the standard has a safety data sheet. This provides the consumer with important information on the safe use of the product in accordance with EU Directive 91/155/EEC. These safety data sheets can be downloaded in our download zone.ISO 19752 Since about 2004, several major OEM manufacturers such as Hewlett-Packard, Canon, Lexmark, Epson etc. have supported a new international standard: the ISO / IEC 19752 (LSA page). This testing procedure defines the page yield for toner cartridges in monochrome (b/w) laser printers. Its robust testing criteria demand high standards of cartridge quality. The following are the key provisions of the ISO/IEC 19752: • Use of a standard page (LSA page) printed in a controlled environment with printer default settings. • A minimum of nine of each cartridge are tested until the printer registers them as empty ("toner low" message). ? This permits a reliable estimate of the average predicted yield (sample size) • Cartridges and printers used represent those available to customers on the open market and are not special test cartridges • Measurements of printing quality which establish an end-of-life criterion • A minimum of three cartridges are tested on three different printers to avoid bias due to printer variability?. • The printing environment is controlled and consistent as temperature and humidity variations affect cartridge yield • Due to worldwide and industry-wide participation, the test criteria reflect objectivity in developing a single consistent standard. K+U Printware GmbH naturally also meets this standard and can therefore assure you of TOP quality. |
