The first man came into my mind is Clark Kent. It is said that he is the only guy who regards glasses as tools. His appearances change with him wearing glasses or not. He can be the famous journalist in the Planet Times and Lois’s husband with cool a pair of men’s glasses. Without them, he can be the guy saves the whole earth for us, the great superman. Maybe we have the worry for me that he may have difficulty in finding his glasses after frequently change his characters. However, after 20 years, he saves this tool that can help him mask himself very well. It seems that he never forgets them.

After watching for the series Super Heroes for two seasons, I still can not figure out the character Noah Bennet cast is a good or bad one. The glasses’ lenses look like a septum in his heart which he uses to hide his feelings. Besides, the glasses can prevent him from the injure coming from the outside world as well as reject others’ warm care. For all the audience, we want to see more clearly about this good father who likes to keep himself busy in office.

In fact, the glasses these great movie stars wear can be found in our daily life. If we are not wealthy enough to buy in those big brands, some cheap and good one can also be a not bad choice. I know a website: www.prescriptionglassesonline.net. I found several pairs of glasses in the same style as Clark’s. I hope you can have the same good luck.

Though compatible cartridges don’t meet OEM standards, they are able to print the document clearly without any problem. Compatible cartridge cannot be used to print photography. You have to use OEM ink cartridge if you want to print film quality prints. Compatible cartridge is cheap and can help you to save up to eighty percents of the original purchase price. This kind of cartridge can be used for occasional printing purposes.

Besides, you will find a larger variety of ink cartridges at the online stores. The online store has a search feature which enables you to search for any type of ink cartridge. You must buy ink cartridge that is compatible with the printer otherwise it won’t function. You need to refer to the compatibility chart if you are buying a third party ink cartridge. If you have a larger budget, you can buy OEM ink cartridge.
It is important to buy third party ink cartridge made by a reputable manufacturer. Before shopping for ink cartridge, make sure you have verified the model name of the printer. Each model of printer has a different number series and name. The best way to check the model name of the printer is to refer to the user manual.

Ink cartridges 10a to 10d have different patterns from each other in positional relationship between projections 12a to 12d and insertion parts 16a to 16d, respectively, and cartridge holders 20a to 20d have different patterns from each other in positional relationship between slits 22a to 22d and ink introducing tubes 21a to 21d, as seen from the direction on which the ink cartridges 10a to 10d are mounted on the cartridge holders 20a to 20d, respectively. At the same time, the respective patterns of the positional relationships in the ink cartridges and the cartridge holders coincide with each other per each of the four colors of black, cyan, yellow and magenta. Thus, any one of ink cartridges is prevented from inadvertently joined to any one of the cartridge holders to which the ink cartridge does not correspond to.

The original manufacturer is familiar with the structure of the printer it made so it is able to produce ink cartridge that is fully compatible. You won’t find any fault with the OEM (Original Equipment Manufacturer) ink cartridge. There is a slight chance of failure if you use OEM ink cartridge. Third party ink cartridge can also work with your printer but it has a lower quality than OEM ink cartridge. As its name indicated, it is made by a third party manufacturer. Third party manufacturer is compatible with several branded printers whereas OEM ink cartridge is only compatible with the specific printer. Therefore, it doesn’t guarantee that it will work with your printer. Many people complain about third party ink cartridges damaging their printers. Your printer is worth much more than the cartridge so it is recommended that you buy the OEM ink cartridge.
Ink cartridge usually has an expiration date. The expiration date is usually 1 – 2 years from the present date. You should avoid buying cartridges that are going to be expired.

The present invention relates to a set of ink cartridges which are filled with a plurality of kinds of inks, ink cartridges included in the set, a method for producing the set of ink cartridges, and an ink jet printer which forms an image with the inks contained in these ink cartridges.

BACKGROUND OF THE INVENTION

In general, an ink jet printer (ink jet recording apparatus) has a construction in which an ink cartridge filled with an ink are adopted to be installed to or mounted on a cartridge case. In such a printer, the ink contained in the ink cartridge mounted on the cartridge case is supplied to a recording head main body through an ink supply needle. (See, for example, Japanese Patent Application Laid-open No. 2000-218813.)

Japanese Patent Application Laid-open No. 2000-218813 discloses an ink jet printer having a cartridge case divided into a larger compartment and a smaller compartment. The larger compartment of the ink cartridge case are provided with three projections in the periphery of respective ink supply needles in an upstanding manner, and the height of the projections is greater than that of ink supply needles. A ink cartridge has three recesses formed in the lower surface thereof for engaging with the three projections of the ink cartridges cases. Accordingly, when the ink cartridges are mounted on the ink cartridge case, it is necessary that the positions of three projections and the positions of three recesses coincide with each other. Otherwise, the ink cartridge cannot be mounted on the ink cartridge case.

Accordingly, by changing the positions in which the projections and recesses are formed or the shape of the projections and recesses per each model of printer, it is possible to ensure that an ink cartridge is mountable only to a cartridge case included in the model of printer to which the ink cartridge corresponds. As a result, it is possible to prevent the ink cartridge from being mounted by mistake on a model of printer to which the ink cartridge does not correspond to.

Third party ink cartridge is compatible with several printer models. The advantage of third party ink cartridge is that it is cheap. However, you must keep in mind that there is always a chance that it won’t work with your printer. If you buy third party ink cartridge, you are risking of wasting money on a cartridge that probably won’t work in your printer. If possible, you should buy the OEM ink cartridge because it is durable and won’t get damaged within a few days.

Remanufactured ink cartridges are made from used or malfunctioned cartridges. Thousands of empty and malfunctioned cartridges are sent to the factories of remanufacturers every year. The remanufacturer will check the condition of the cartridges before reconditioning them to meet the standards of OEM cartridges. Majority of remanufactured cartridges are made from empty cartridges. Empty cartridges are refilled with new inks. The inks are not produced by original manufacturer so they have more inferior qualities. If it is discovered that the cartridge has damaged part, the damaged part will be replaced with a new part that is functional.

If you want to buy cheap ink cartridges, you should shop on the internet. On the internet, you will come across many online stores that are offering discounts on ink cartridges. You get to save money when you use coupon code. Coupon code can deduct the price of the ink cartridge so that you pay lesser and save more money. You should visit several online stores so that you have more selections. Shopping with several stores allow you to compare prices and find out the store that is offering the ink cartridge you need at the cheapest price.

==========================
Most users of inkjet printers prefer to refill and reuse ink cartridges rather than use new ink cartridges because the new ink cartridges are expensive. In an effort to satisfy the above-mentioned preference of the users of inkjet printers, some ink cartridge manufacturers have proposed and marketed ink cartridges that are provided with refill nozzles to allow users to refill ink cartridges through the refill nozzles.

Korean Patent Laid-open Publication No. 10-2003-69596, which was published on Aug. 27, 2003, discloses a conventional ink cartridge refill system that is configured as a refill system to be used by someone in the business of refilling customers’ ink cartridges. The above-mentioned refill system is constructed such that an ink cartridge is loaded in a cartridge loading unit and is refilled with ink simply by manipulating a control switch of the cartridge loading unit.

Herein below, the conventional ink cartridge refill system 100, disclosed in the above-mentioned Korean Patent Laid-open Publication Gazette, will be described with reference to FIGS. 1 through 4.

As shown in FIG. 1, the conventional ink cartridge refill system 100 includes a plurality of cartridge loading units 110 in each of which an ink cartridge (not shown) to be refilled with ink is loaded. The refill system 100 also includes a plurality of ink reservoirs 120 to inject ink, temporarily contained therein, into ink cartridges loaded in the cartridge loading unit 110 through a plurality of ink injection hoses 101, and an ink tank 140 which stores ink therein and supplies ink to the ink reservoirs 120 through a plurality of ink supply hoses 102. Furthermore, a plurality of pressure cylinders 130 is connected to an air compression pump 150 through a plurality of air hoses.

OEM ink cartridges can be more expensive than the printer itself. If your printer is cheap, you should get a third party ink cartridge instead of OEM ink cartridge. Third party ink cartridge can perform as efficiently as OEM ink cartridge but you must make sure it is made by reputable third party manufacturer. Many third party manufacturers are certified by a licensed authority to ensure the minimum industry standard is met. You must be careful when shopping for a third party ink cartridge as many manufacturers use lousy parts to produce them. To avoid this problem, you should read reviews on different third party ink cartridges. By reading reviews, you will know which ink cartridge can function properly. People who get cheated after buying an inferior cartridge will post their reviews on the internet so that other people know.

If you prefer OEM cartridge, you can get a refurbished ink cartridge for your printer. Refurbished ink cartridge is made according t the OEM standards so it will work perfectly with your printer. However, refurbished ink cartridge is made from used parts. It is made from cartridges that are previously recycled customers. The cartridges are recycled because of some flaws. After the cartridges arrived at the factory, they are being reconditioned according to the type of defects they have. Empty cartridges are refilled so that they can be resold as refilled cartridges. Cartridges with malfunction parts are repaired by using third party parts so that they can be sold as remanufactured cartridges.

=====================
Disclosed herein is an ink cartridge refill system for inkjet printers and a method of refilling ink cartridges using the system. The refill system includes a vacuum pump to supply ink from an ink tank into a cylinder and to forcibly draw ink from an ink cartridge, as well as an air compression pump to generate a compression force to inject ink from the cylinder into the ink cartridge through the nozzle of the cartridge. The cylinder is connected at the inlet end thereof to both the air compression pump and the vacuum pump, and is connected at the outlet end to both the ink tank and the ink cartridge. Both a compression pump line and a first vacuum pump line which pass through the cylinder are connected to the nozzle of the cartridge through an ink supply hose. The vacuum pump includes a second vacuum pump line directly connected to the ink cartridge, as is the first vacuum pump line passing through the cylinder. Both the ink supply hose and the second vacuum pump line are connected to the nozzle of the cartridge through a connection unit. The refill system can regulate the inner pressure of a refilled cartridge by removing predetermined small amounts of air and ink from the refilled cartridge, and can completely remove waste ink from the cartridge at the initial stage of a cartridge refill process when necessary.
