Description

The coupling of HP IIISi series toner cartridge assembly

Technical field

The present invention relates to a kind of HP of being applicable to LJIIISi/4Si/4SIMX/IIISi-P/II/III/IID/IIID series printer coupling between organic light guide drum, magnetic roller, corona wire, powder delivery cutter, cleaning doctor and the ink powder in the cartridge.

Background technology

At present, compare with other models, the charging unit of this model is a corona wire, and its mode that photosensitive drums is implemented charging is different with the charging roller in other models.Though coupling that should the series toner cartridge assembly in the tradition exists, but coupling is not effectively considered organic light guide drum comprehensively, the magnetic roller, corona wire, the powder delivery cutter, the mutual performance impact of cleaning doctor and ink powder causes quality uneven: effective usage ratio of ink powder is on the low side, the whole life-span can produce the useless powder of the not transfer printing of the surplus powder that does not use of 15g～30g and 10g～30g, produces waste and pollutes; The print quality discreteness is bigger and unstable, especially in the middle and later periods in cartridge life-span, and because of each accessory depletion occurs often owing to mismate, the phenomenon of function diminuendo, the print defect showed increased can't satisfy the printing demand; The single page powder consumption is more than 0.04g, and can 400g～450g amount of toner can only print 7000～8000 pages, causes overall cost too high.

Summary of the invention

In order to prolong the serviceable life of cartridge, reduce and print cost, economize on resources, the fixing coupling of producing of a kind of cartridge provided by the invention, by matching specific organic light guide drum, magnetic roller, corona wire, one-component negative polarity magnetic ink powder, powder delivery cutter and cleaning doctor, make each assembly property reach optimum matching, can overcome the deficiency that present factory formula brings.

The present invention realizes by the following assembly of coupling:
