Basic Knowledge On Inkjet Printers

Computers use inkjet printers to create printed work executed by command by contact of tiny ink droplets on paper. It is the most widely use printer and comes in a variation of sizes with a range of prices for whichever work its intended for. It has been around for a long time and its performing ability has been made better making the purchasers range even wider.

There are two forms of technology employed on this printer. There is continuous inkjet which use the idea of droplets that a charged being introduced to an electrostatic field at high velocity most amount is recycled thereby using a small amount in printing. It is quite fast in printing hence getting rid of slow printing.

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 on the other hand uses a piezoelectric material different from the other one which employs use of a heating element. This makes open to different types of ink since it does not need volatile substance.

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.

Inkjet head are in two main designs. There is the fixed head which is an in built head and should last as long as the printer does. Obtaining a replacement head if it gets damaged can be expensive though some cannot be replaced and this means replacing the printer itself. There is also a disposable head which comes as part of ink cartridge that is replaceable. When this ink is exhausted the entire print head and cartridge will be replaced this deals with the issue of damaged print head.

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.

As compared to earlier types of printers, inkjet printers do not make as much noise and they print better detail. In comparison to more expensive types of printers, they take short warm up time, its printing costs as per page are cheaper in comparison other than with laser printers. It disadvantages that is expensive ink and cartridge has been sorted out by third party manufacturers.
