How does an ink cartridge work ?

Saturday, July 12th, 2008
by Andrew James

An inkjet cartridge is the replaceable component of an inkjet printer that contains the ink used when printing. The ink cartridge can also contain the print head itself. Every ink cartridge is made up from one or more partitioned ink reservoirs and some producers also insert electronic contacts and a chip that transmits information to the printer.

Before printing anything, the ink level must be checked. If it is too low, ink may dry on the print head and lead to low quality prints. The ink must have a smooth flow in order to produce high quality prints. To clean the dried ink from the print head, it is strongly advised to gently rub the head with isopropyl alcohol on a swab or paper towel.

In most cases, ink cartridges are very expensive. Many people prefer to use compatible ink cartridges, made by a company other than the printer manufacturer. These cartridges can sometimes match the quality, but with possible savings. Another alternative involves some modifications to allow the use of continuous ink systems that use external ink tanks. Some people even choose to use aftermarket inks. They can refill their own ink cartridge, buy aftermarket remanufactured brands, or even take them to a local refiller to refill them.

The costs of replacing ink cartridges, compared to the price of a brand new printer, amaze many of the customers. Leading printer manufacturers like Hewlett Packard, Lexmark, Dell, Canon, Epson and Brother often loose money by selling cheap printers. They must recover these losses and make a profit by selling very expensive cartridges over the life span of the printer. Because companies producing aftermarket ink cartridges take away a part of their profit, major printer manufacturers have taken action against them. Some manufacturers even took legal action.

Many printer owners choose to refill their cartridges or buy remanufactured cartridges from third parties over buying new cartridges. This saves them a lot of money (they only have to buy the ink and a few other small raw materials) and gets them almost the same quality. A whole industry has grown up around ink cartridge refilling. Customers can find several qualities and types of refilling. However, some are safe and successful while other types can destroy the printer or produce low quality prints. Some of the options are to take the empty cartridges to refillers or remanufacturers, or buy store branded ink.

There is one more thing the consumer can do: refill their own cartridges. Most cartridges have instructions on how to use and refill on the Internet. Bulk ink sellers can also be found on the Internet. They offer pints, quarts, and even gallons of ink. One single pint (473 ml) can refill between 15 and 17 large cartridges (of 27 ml capacity).

Brother, Canon, Dell, HP, and Lexmark cartridges ink cartridges are very easy to refill manually. By using a simple syringe, you can fill some of them. All you need is ink. However, Epson cartridges are usually hard to refill and need a chip resetter. This tool resets the counter chip inside the cartridge. Refilling process can be messy as it involves handling ink directly. Some experience is needed to make the process as clean as possible.

Laser/toner cartridges labeled as “compatible” are often refilled cartridges. Many third parties offer newly manufactured cartridges. Ink cartridges labeled as “compatible” are all newly produced. “Remanufactured” inkjet cartridges have been used previously and refilled by a third party so caution is advised when buying them. These cartridges may not work like new ones.

Benefits of Computer Training

In today’s modern world, computer training is considered to be of vital importance to almost everyone. Whether you are entering the workforce, are on a senior management team, or you are a recent retiree, computer skills are a must. Around the world over, it’s not just about basic word processing and balancing your check book anymore, either. The computer has invaded almost every facet of our modern lives, and thus it has become a necessity to be able to use and understand the computer.

Technology is a fast moving industry and is therefore, always changing. Whether you are a novice, an intermediate or a professional there are computer training options available to enable you to get the most from your computer.

Traditionally, computer training has taken place in a classroom. In high schools across the country, many young people are being trained in computer use. In fact, it starts much earlier today in developed countries like the United Stated, Australia and the United Kingdom. Colleges also offer courses on computer use, and some of these are geared towards the adult who has never been on a computer before.

Correspondence courses are gaining in popularity. Distance learning offer the student the advantage of learning at their own pace within their own home. The only drawback is the lack of a hands on approach gained from a classroom environment. You can’t just raise your hand and have your query answered immediately.

Online computer training is emerging today as a force to be reckoned within educational circles. Not only is computer training taking place online, training for just about anything else can be done online as well! Online classes are available for many colleges, and some offer complete course loads online, so you can get a college degree completely from home, through training conducted on the Internet.

One final method of computer training that is worth noting is that of software tutorials using video and/or software. This arena was unknown in the beginning of the quest for computer knowledge (as was the online training), largely because the computers of the past did not possess enough power to run such programs. However, today you can purchase specialized software or videos that will provide you training at your own pace, hands-on, without having to be online.

In conclusion, it goes without saying that computer training is an invaluable service that needs to be on the ‘to do list’ of anyone who is serious about communicating or being productive in our modern society. There are an endless variety of ways to get this training, and some people even prefer to teach themselves based on specific subjects of interest and their ability to conduct research.

Getting The Most Out Of The Latest Technology In Mobile Phones

Thursday, July 10th, 2008

There has been much development in recent years when considering the mobile phone industry. Mobile phones are becoming vastly popular- often replacing landline phones because of their better features and mobility. And with newer technologies coming out each day, the mobile phone is starting to become a technological powerhouse.

For those who are a photographer at heart, the mobile phone is a great way to take pictures on the go. Mobile phones are commonly about the same size as a digital camera, and recent technologies have enabled them to be on par in terms of resolution and picture quality. It isn’t uncommon to see a 6 mega-pixel camera on today’s market- something that was unheard of just 10 years ago!

It’s hard to imagine using a mobile phone without also considering the prospect of being networked with friends and family members. But networking on today’s standards is much different. We now have Bluetooth and infrared technologies that can connect devices without a thought of a wire. Wireless technologies are also becoming popular in business-class phones, where actual Internet access can even be obtained from wireless Internet spots.

Today’s society is absolutely riddled with video games. It isn’t hard to estimate that the mobile phone would succumb to this fact sooner or later. Indeed it has, as some mobile phones such as the Nokia N-Gage have already dedicated most of mobile hardware technologies in making a mobile gaming platform. This obscures the line between game console and mobile phone, but rest assured, the mobile phone won’t be overtaking the home console market anytime soon.

A big topic in mobile phone industries today is the usage of the 3G network. The 3G network stands for “third generation,” in which the previous two were slower, less functional, and less appeasing to customers. The next generation, 4G, is likewise slated to be faster, better, and stronger than that of previous mobile networks. It’s an exciting race coming up to see who can build the best network- either way, consumers win.

Lastly, mobile phone companies are now starting to input innovative features such as the global positioning system as an everyday feature for consumers. Already, mobile phones are able to send emergency hotlines location data for those who are on their mobile phone at the time of the call. This functionality is being extended to the consumer range for applications such as finding a certain location, getting driving instructions, and even estimated times of arrival. There is still room for expansion, but already the GPS is proving to be a vital consumer application in mobile phones.

In Conclusion

It’s tough to tell where the mobile industry is going, but it’s easy to say where it’s been. The mobile phone industry has made considerable progress over the years, and there is no signs in showing that this progress is slowing down any. Mobile users get the benefit of this upstart in technological advances, although it doesn’t always come cheap. It won’t be long until mobile phones become multi-use consumer electronics, but many would attest that they have already become so with their vast features and options.

The Truth To Effective Use Of Adware Spyware Blocker Software

Wednesday, July 9th, 2008
by James Redder

Coming up with online sources for her law school thesis on money laundering was a task that was made simpler for a certain student with the help of Google. This easy tool was extremely useful to the student in her writing process. A couple months after beginning her project, the student became distressed to discover that her trusty search engine began leading her to a web page unrelated to money laundering.

Though she originally believed it was a glitch in the internet search systems, the persistence of the annoyances led her to believe that she had been bugged. As far as irritations go, human beings that bug us are the most easy to fend off. The law student, however, had been infected with a far more persistence predator to fend off: adware and spyware programs. As her computer was primarily for personal school-related use, the student’s technology skills were constricted to the most basic of online research and writing.

Seemingly complex computer problems that boggle the minds of most computer uses, like the law student, can typically be summed up with the words spyware and adware. In 2000, the word ’spyware,’ which had been around since 1995, became a fixture in most people’s computer dialogue. Personal information is infiltrated in this method, using either a software or script that allows another person access to the computer.

This is done by studying logging keystrokes, web browsing history and even scanning a user’s hard drive. Though spyware employs the kind of methodology that sounds like it came out of a James Bond movie, anyone can be a victim. It is not an exaggeration to call the people affected by spyware victims because nobody wants their internet activities to be monitored without their consent. Admittedly spyware has beneficial uses such as allowing the tracking of criminals, but those potential uses are frequently ignored as crooks use the program for their own criminal activities, such as stealing credit card information. Because of the hostile nature of these potential infiltrations, every computer should have an updated anti-spyware program.

While blocking spyware, you should also block adware and malware to fully protect your system. Online adware and spyware blocker programs are easily available to help in this endeavor. Preventing any additional downloads of malignant programs, blockers also help get rid of any current malicious programs or scripts downloaded onto your computer.

Conclusion

By preventing typical computer usage, spyware, adware, and malware can be just as troublesome for the average computer user as the self replicating viruses and worms. Both the individual programs and the computer itself can experience a drastic decline in speed after the computer has been infected with these programs. Along with the trouble they cause, occasionally spyware is sneaky enough to hide from detection, which allows the crime to continue unpunished. Being proactive with a good blocker is the way that a computer owner should protect his system from allowing these programs to cause his computer harm.
