An Idea On Inkjet Printers

Inkjet printers are usually used by computers to print commands by impacting droplets of ink onto paper for printing. It is the most popular printer and is available in various sizes for a wide range of prices whether you need one for consumer use or for commercial use. This printer can be said to have been in use for a long time and due to this its performance over the years has been made better increasing the range in which a buyer can choose from.

It uses two types of technologies. There is the continuous inkjet which basically uses charged droplets of high velocity on an electrostatic field. A small amount of the ink is actually used in printing while the rest is recycled. This method results in printing at great speed. This therefore means that printing speed is not a problem.

There is also the drop on demand technology which is further divide into two, thermal and piezoelectric. Thermal inkjet printers technology employs passing of a current pulse through a heating element which results in quick vaporization of ink to a bubble, increasing pressure and thereby propelling an ink droplet on the paper. Its ink is normally aqueous as it easily forms vapor bubbles. It is worth noting that the technology behind this printer is different from thermal printers.

Piezoelectric inkjet uses piezoelectric material unlike the other which uses a heating element. It is flexible for a variety of ink as it does not require volatile component.

Ink used on these printers is water soluble and not expensive to manufacture the problem with it though is that it is not easy to control it on media surfaces. This type of ink is used on thermal heads since they require water to work. There are several ink types available, soluble, hard soluble, mild soluble, inks curable by UV and those that sublime with dye. The print outcome of these inks varies by different standards in quality and duration.

There are two main types of inkjet head. First is the fixed type which comes built into the printer and is expected to last the life of the printer replacement is expensive and for some it might require replacement of the printer itself. Second type is a disposable head which is part of replaceable cartridge. This means if a print head gets damaged replacing it will not be difficult in fact it is just like refilling an exhausted ink cartridge.

When ink dries up it may clog the nozzles and this calls for cleaning. Some come with a manual cleaning mode which the operator can clean it manually. A clogged nozzle may be soaked in water so as to unclog.

In comparison to other printers, inkjet printers have several advantages they are less noisy compared to earlier printers and also print finer and smoother details. In comparison to more expensive technology they have dont take a long time to warm up and printing costs per page are less, except as compared to laser printers. Disadvantages such as expensive ink and cartridges have been taken care of by third party manufacturers of the same.
