Background technology
Modern print cartridge generally refers to be used for storing marking ink, and be finally completed the component of printing in ink-jet printer.
From the composition structure of print cartridge currently on the market, generally speaking, it can be divided into：Split type ink box and integral type print cartridge.One
Formula print cartridge：Nozzle is exactly integrated on print cartridge by integral type print cartridge, as soon as after ink is finished replacement new print cartridge, is also anticipated
Taste while has replaced a new print head.Higher printing precision can be realized using this print cartridge, and can be protected
Print quality is demonstrate,proved, since nozzle is with replacing ink cartridge, will not decline print quality because of the abrasion of ink gun.But
This cartridge designs structure increases cost, and the price of such print cartridge is all relatively high.HP, Lexmark product use this
Class print cartridge.But currently in order to save printing cost, for this kind of print cartridge, user in print cartridge after having used up, often voluntarily
Fill ink again into empty cartridge, as long as in general operation is correct, the ink after charging will not cause nozzle much injuries.I.e.
Make the print cartridge that also only a script should just be scrapped for not succeeding, scrapping, printer will not generally be caused
Injury.Certainly, this kind of print cartridge is also impossible to limit the number of filling ink to user, in general, is being finished original-pack ink
Later, it can also fill 3~4 times.If it find that if print quality is decreased obviously, a new print cartridge is needed replacing with regard to explanation

Print cartridge from cost for, it is more lower than integrated print cartridge, but this kind of print cartridge is user not to be allowed at will to charge ink.
In Split type ink box, single-color ink box and polychrome print cartridge can be divided into according to the situation of color again.Single-color ink box refers to each face
Color individual packages are finished any color and change any, will not cause to waste.And polychrome print cartridge then refers to multiple color
It is encapsulated in a print cartridge, if a kind of color has been used up, even if other several colors have, it is also necessary to entire print cartridge whole
It changes.It will be apparent that single-color ink box is more economical.
Either Split type ink box or integral type print cartridge, current most print cartridge is in order to ensure print cartridge in print procedure
Ink supply is smooth, and the ink-jet of print head uniformly sprays, and sponge is all added in the inside of print cartridge, the size of entire sponge almost fills out
The cavity of entire print cartridge.For most of print cartridges all using sponge etc. as sorbing material, this print cartridge is arrived in work cannot be normal
