Therefore, re-use these components to consider their life issues, can not follow the previous experience, past the magnetic roller can be used PX 2-3 cycles, but in recent years out of the printer in the magnetic roller and then a cycle may have a dangerous. But from the compact structure and performance of certain components, original products has continued to improve with, in order to make the print product more uniform and improved in a number of drum machines on the drive, such as from 97 years to the 2001 launch of the HP4000 printer launch of the HP1200, the photosensitive drum from the previous gear drive into the side of the spline drive, this improvement makes the process of transmission of vibrations caused by the greatly reduced drum, print materials more evenly. This kind ofgreen laser pointerhas the function of browsing the document.
To improve the reliability of sealing in the HP4000, HP2100, HP5000 in magnetic hard-metal seals to replace the blankets, blankets to avoid leakage, separation, curling and other failures occurred; some type of scraper two alternative sealing materials with felt a sponge, reducing the leakage of powder from happening. Charge roller by a hard rubber foam structure into a structure, not only reduces wear and tear on the photosensitive drum, while making the noise is greatly reduced. In fact, the original product has been doing this or that change, which requires us to work in a careful and detailed observation and analysis, only the original product with full understanding, in order to effectively use the original old pieces, so that refurbished products more reliable, more energy save, renovation is more valuable. The document browsing function of green laser pointer can be added for this kind ofgreen laser pointer.
Three-layer structure by the charge roller general form, the middle is a good rigidity of the conductive metal material, the outside is wrapped in conductive rubber, the outermost layer is the protective layer, and its role within the one hand, to prevent the conductive rubber plasticizer overflow (will corrode drum coating), and to stop the moisture; the other hand, from the charge blocking effect, to prevent charge leakage, the higher resistance than the inner layer of rubber, it is also known as resistive layer. In the toner box, leaning against the drum charge roller is dependent on the friction with the drum rotating together with the drum, drum and charging roller is only an air angle between the charging roller is the angle of the air through ionization and the photosensitive drum charged. The design of document browsing ofgreen laser pointeris specially determined yesterday.
Therefore, to charge the photosensitive drum to drum but also brings wear, the more rigid materials, the greater the wear on the drum, and with the rotation speed increases, the noise will produce more and more, HP and CANON in low-speed machine uses a hard rubber type material, because the rotational speed of the lower friction of the drum is smaller, the noise is small, with a high speed continuous introduction of new models, charging hard rubber roller is no longer fit new requirements, if used in high-speed machine, the drum will not only cause greater wear and tear, and will have ear-piercing noise, so CANON developed a soft foam-type charge roller, not only made more uniform charging performance, and reduced wear and tear on the photosensitive drum, which reduces the noise. The customer is very interested in the document browsing function ofgreen laser pointer.
But the foam roller charging more complex production process, the foam in the hole to the size of strict control in order to ensure a uniform charge, so production costs are higher; in our renovation work needs to note that the soft charge roll more than the hard charging roll deformation, and this deformation is irreversible, in the store when we must pay special attention. When opening an old cartridge, you will find almost all of the components are Nianman toner, before re-assembling them how to clean it? Our aim is to re-use these parts, so cleaning these parts to avoid causing damage, so the compressed air to become the preferred method of cleaning parts.
