Abstract
The invention relates to a matched toner cartridge assembly for HP Color LaserJet 4500 and Canon EP-83 series printers. Through specifying the range of the geometry parameters and the physical parameters of a magnetic roller, ink powder, a powder feeding cutter, and the like, various assembled parts reach the best performance and mutual matched effect, thereby decreasing the generation of waste powder, prolonging the printing service life of the toner cartridge, greatly decreasing the printing cost, lessening the environmental pollution and saving resources while ensuring the comprehensive printing quality.
Description
Technical field
The present invention relates to a kind of HP of being applicable to Color LaserJet 4500/8500, Canon EP-83/EP-82 series printer coupling between magnetic roller, powder delivery cutter, the ink powder in the black carbon powder box.
Background technology
At present, the production coupling of this cartridge is only carried out simple proportioning, influencing each other between consideration magnetic roller not yet in effect, powder delivery cutter and the ink powder, cause product quality uneven: the effective rate of utilization of ink powder is on the low side, after the end-of-life, there is the surplus powder participation printing of 40～50g to cause bigger waste in the powder storehouse, and environment is had than severe contamination; And the print quality instability, especially in the middle and later periods in cartridge life-span, because the mismate between each accessory causes a lot of parts the phenomenon of major injury to occur, the print defect showed increased can't satisfy the printing demand; The single page powder consumption of printing 5% coverage rate is more than 0.04g, and can 450g～500g ink powder could print 10000 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, select specific magnetic roller, one-component negative polarity magnetic ink powder, powder delivery cutter for use by calculating, make each component capabilities reach optimum matching, overcome the deficiency that present factory formula brings.
The present invention realizes by the following assembly of coupling:
1, magnetic roller: magnetic field homogeneity is good, and ink powder can evenly be adsorbed; The conductive coating roughness increases to roughness with 180 order white fused aluminas down by the air pressure with 0.1mpa and keeps Ra=1.5 μ m～1.9 μ m, makes toner particles obtain uniform electrostatic charge by the friction of powder delivery cutter and magnetic roller.The developer roll surface coating must be evenly, and the linearity of developer roll can produce harmful effect to printing with beat in addition, linearity is not enough produce bad may to appear at straight line inhomogeneous, beat caused badly can the formation level prints badly, the circular runout requirement is little.
2, one-component negative polarity magnetic ink powder: constituent is a carbon black, magnetic oxide, resin, the ratio of lubricant and adjuvant is respectively carbon black 1%, magnetic oxide 41%, resin 55%, lubricant 2%, adjuvant 1%, make greasy property, flowing property, the colourity of ink powder reach optimum condition, the charged ability of unit volume ink powder reaches carried charge and equals-16uc/g～-17uc/g; Toner particle diameter evenly, distribution range is controlled at and accounts for 1.5% below the diameter 5 μ m, account for 1.5% more than the diameter 8 μ m, diameter 6.5 μ m～7.5 μ m are more than 90%, and the toner particles of participating in development and final transfer printing is reached more than 98%; Softening point is 130 ± 3 ℃; But flowing property degree of scatter＞40% between the toner particle under rated condition, the nominal value limit deviation is 20%; Apparent density is 0.48g ± 0.02g/cm
3
3, powder delivery cutter: make by metal frame and the stickup of PU adhesive tape, the PU adhesive tape is a workplace, require PU adhesive tape thickness even, flatness is good, hardness=HD71 ° ± 3 ° A, and the pressure between maintenance and developer roll is evenly constant, produces suitable static charge to guarantee toner particles friction owing to powder delivery cutter and magnetic roller under this pressure, and the magnetic roller rotates 300,000 circles or places 5 years powder delivery cuttves and elastic force depletion can not occur.
Embodiment
20 ℃ ± 4 ℃ of temperature, in dustless, the no static environment of relative humidity 35%～60%, in cartridge, assemble above-mentioned accessory by following requirement:
At first, left magnetic roller conducting end bias contact is coated an amount of conductive paste; Secondly, powder delivery cutter front cutting edge is kept 30 ° of parallel assemblings in angle with the horizontal axis of magnetic roller, after fixing, rotate the 2-3 circle, guarantee that the running of magnetic roller is smooth and easy; At last, powder delivery cutter, magnetic roller are required parallel being seated, the one-component negative polarity of packing in cartridge powder storehouse magnetic ink powder according to the cartridge shell mechanism.
The whole print quality of cartridge is improved significantly, and concrete advantage is as follows: 1. the ink powder transfer efficiency can improve 5～10 percentage points, totally is controlled at more than 95%, and the useless powder of cartridge can reduce more than 85%; 2. density uniformity can improve 3～5 percentage points, can be controlled between the 1.0-1.5, guarantees that print image is evenly clear; 3. the firm degree of photographic fixing can improve more than 5%; 4. be used for HP Color LaserJet 4500, Canon EP-83 series cartridge, powder filling 400g ± 5g, just printable 10000 pages (A45% coverage rate) saved cost greatly; 5. be used for HP Color LaserJet 8500, Canon EP-82 series cartridge, powder filling 500g, just printable 11000 pages (A45% coverage rate) saved cost greatly; 6. the whole life performance of cartridge is stable, and print quality is good, and print cost per page can be from 0.15 yuan of 0.24～0.3 yuan/Zhang Jiangzhi/open.
Claims (1)
1. one kind is applicable to HP Color LaserJet 4500/8500, the Canon EP-83/EP-82 series printer coupling of toner cartridge assembly, magnetic roller, one-component negative polarity magnetic ink powder, the powder delivery cutter of apolegamy particular characteristic is characterized in that making assembly property to reach optimum matching:
The magnetic roller: surface roughness Ra=1.5 μ m～1.9 μ m,
One-component negative polarity magnetic ink powder: 1. the carried charge of unit volume ink powder be-16uc/g～-17uc/g, 2. softening point=130 ± 3 ℃, 3. carbon powder particle 90% above diameter is between 6.5 μ m～7.5 μ m, but 4. degree of scatter＞40% between the toner particle, 5. apparent density 0.48g ± 0.02g/cm
3,
The powder delivery cutter: metal frame and PU adhesive tape are pasted and are made, and the PU adhesive tape is a workplace, and PU adhesive tape thickness is even, and flatness is good, hardness=HD71 ° ± 3 ° A.
