Description
Technical field
The utility model relates to publish machine field, more specifically to a kind of publication machine developer roll auxiliary locator.
Background technique
Publication machine i.e. printer are one of output equipments of computer, for computer disposal result to be printed upon
On associated media.The index for measuring printer quality has three: print resolution, print speed and noise.The type of printer
Very much, whether there is stroke to paper by type element, divide impact printer and non-impact printer.
Developer roll is building block important in printer, and when developer roll works, surface is with (the effect of charge adsorption carbon dust
Be equivalent to magnetic roller), when input print data after treatment, be converted into corresponding laser signal, pass through one group of refraction by prism
To the surface toner cartridge (OPC), to form charge latent image (specific " image " or " text " information of charge composition).When OPC rotates
When by developer roll, corresponding carbon dust is adsorbed from developing roller surface in latent image part, forms carbon dust reality, when OPC carries carbon dust reality
Paper corresponding position is turned to, carbon dust can be adsorbed onto paper surface again by the paper by electrostatic treatment.In this way, piece image is
Through appearing in paper.
The positioning method of developer roll is fixed by developer roll positioning shaft sleeve, so that the center of photosensitive drums and developer roll is away from being
Fixed, and since dimensional accuracy of the glue part in injection moulding process is relatively difficult to guarantee, the dimensional accuracy of the colloidal materials of developer roll
Also it is relatively difficult to guarantee, so that photosensitive drums cannot come into full contact with developer roll, whitens so as to cause printing when printing test, thus shadow
The usage experience of user is rung.
