Toner cartouche

toner cartouches contain a so-called single component toner and usually also the developer unit, which is renewed with an exchange equal with.

Toner is an extremely fine powder, which should not arrive uncontrolled into the environment. For this reason the toner is supplied with small and middle copiers or laser printers in a locked unit.

The advantage of very simple and clean changing opposes contrary to the toner in loose bundles a higher price.

One differentiates between original, alternative, Rebuild and Refilltonerkartu. Original ones come from the respective printer manufacturer, so-called oem and are usually completely again manufactured. The original manufacturers fall back however also to components, which were already once used. Those are z. B. Housing components, which wear resistant or - are free. Alternative offerers produce similarly as the original manufacturers, however also these fall back to Gehäuseteile, the z. T. from original cartouches come. Also new Gehäuse-teile are blocked. With Rebuildtonerkartu the wearing parts are replaced by new parts, or using parts, which have a good condition. The quality is acceptable and about 10-30 per cent more inexpensive than the OEM products. Refilltoner are only refilled and therefore qualitatively inferior. One risks a strong contamination of the equipment. However the price is often more favorable up to 60% than the OEM product. But the risk its printer to get dirty much more highly.

In the DIN 33870 for Rebuild and Refillkartu (recycling cartouches) minimum requirements are specified. However expressed few recycling cartouche offerers produce standard-conformal products. Only standard-conformal recycling products can be compared objectively. With all other products one must rely on the statements of the offerers.

Since approximately 2004 some large oem manufacturers, like Hewlett-Packard , support Canon, Lexmark, Epson etc., a new international standard: the ISO/International Electronical Commission 19752 (LSA letter). This testing method determines the pressure achievement of toner cartouches in mono chrome (s/w) laser printers. This testing method places high quality requirements against the expendable material. This is a summary of the test criteria to the ISO/CInternational Electronical Commission 19752:

• Use of a standard side (LSA letter), printed in a controlled environment with standard printering positions.

• Min. become. nine pieces of each cartridge tested, until they are recognized by the printer as empty (toner Low message). Thus an average value of the pressure achievement which can be expected is determined.

• The used cartridges and printer come from the free market and are no special test cartouches.

• Measurements of the pressure quality, which set up a use end criterion.

• At least three cartridges on three different devices are tested, in order to exclude influences by hardware differences.

• The pressure environment is kept controlled constant, since temperature and humidity fluctuations affect the pressure achievement.

• The test criteria represent an objective standard by the world-wide and industry-far participation.
