Compatible and OEM Ink Cartridges – Is there a difference?
Choosing between OEM and compatible ink cartridges can be a confusing process, as manufacturers and other consumers often give conflicting advice about which is the best choice. Manufacturers claim that using non-OEM cartridges could result in reduced print quality, but what is there really a difference? Let us look at some of the major factors involved.
For the majority of buyers, the reason they consider compatible ink cartridges instead of OEM is to save money. In almost every case, buying compatible cartridges will save a significant amount over OEM prices, sometimes up to 75% savings. This gives compatible cartridges a big advantage for buyers who are looking to reduce costs.
OEM manufacturers often claim that their products will provide sharper quality and better color output than compatible cartridges. In most cases, compatible ink gives the same quality output for a lower price. The cartridges are designed to meet or exceed the specifications of the originals, so there is no reason they should not. However, it is important to buy compatible cartridges from a seller with a reputation for quality. Many good sellers offer a satisfaction guarantee so that the product can be returned if it does not meet your expectations.
Lastly, many users tend to perpetuate a myth that using compatible cartridges will void the warranty on their printer. This is not true. In fact, there are many laws against manufacturers who do not honor a warranty for this reason.
While there are no significant differences between OEM and compatible ink cartridges, many buyers only buy OEM cartridges, despite the potential cost savings. Often this is based on poor experiences with low-quality compatible cartridges that led buyers to believe that all compatible products are made this way. If you decide to go with compatible ink cartridges, it is important to find a reputable seller who stands behind their products with a satisfaction guarantee.

Top 5 Desktop PCI-E Graphics Cards
When looking at desktop PCI-E graphics cards, there are a number of criteria that a buyer might use to determine the best card for their needs. Some buyers may look for the fastest performance, while others want the best value for the money. Using as many of these different criteria as possible, here is our list of the Top 5 Desktop PCI-E Graphics Cards.
1. AMD Radeon HD 6990
Although its release has been postponed to the first quarter of 2011, the Radeon HD 6990 looks poised to be one of fastest graphics cards on the market at release. With two Cayman cores, it may meet or exceed the performance of two cards running in CrossFire, making it the fastest card yet.
2. Nvidia GeForce GTX 580
The GeForce GTX 580 is one of their top-performing single-GPU cards, with great performance and still a relatively affordable price. Its 512 shader cores make it a force to be reckoned with, and its fairly compact size won’t take up as much space as a two-card array.
3. Nvidia GeForce GTX 570 As a less expensive option from the 580, the GTX 570 has fewer shader cores at 480, as well as fewer texture units, but its performance is still very fast. For gamers who want great performance and sharp graphics without paying too much for it, the GTX 570 is a good value.
4. AMD Radeon HD 6970 As AMD’s fastest single-GPU card, the Radeon HD 6970 offers solid performance for those who don’t want the added hassle and expense of dual cards. It sits at a good middle-ground between price and performance, though it is still expensive for all but the most serious gamers.
5. AMD Radeon HD 6950 Calling the Radeon HD 6950 a paired down version of the 6970 would not be doing it justice, as this card offers most of the performance of its more expensive brother at a bit lower price. It is a good choice for gamers who want to save a bit more money for a single-GPU solution.
Common Issues With Xerox Phaser Solid Ink Printers And Solutions
Solid ink printers have recently become more popular, especially in office environments, as a replacement for traditional laser printers. Part of the appeal of solid ink printers is that they produce less waste and are often less expensive to run and maintain than laser models. However, they are not immune to occasional problems. Here are a few common issues of Xerox Phaser solid ink printers, and some possible solutions.
Light Stripes
Some printouts may exhibit light vertical lines that often run the length of the paper. Most printers have a menu option called “Eliminate Light Stripes” for this very issue. It is usually located under Troubleshooting – Print Quality Problems in the menu. Run this feature a few times then print a test page to see if the problem is solved.
Printing Is Slow to Start
If you find that your Phaser printer is slow to start printing, adjust the power saving settings for quicker starts. Turning Fast Resume on will make printing start faster, though it uses more power throughout the day. You can also adjust the amount of time before the printer enters standby mode.
Problems After Moving Printer
One of the most common problems is bad print output after the printer has been moved. This is often the result of moving the printer before it has properly cooled down. Consult the manual for the proper cool down procedure before moving a solid ink printer. Unfortunately, once this problem exists, it generally requires a repair technician to fix.
Printer Using Too Much Ink
Many users may find that a solid ink printer seems to be using too much ink, specifically that it is dumping a large amount of ink in the waste reservoir of the printer. The printer will generally dump excess ink to remove air from the printhead. This problem is especially present when the printer loses power. To remedy this issue, make sure the printer is not losing power during the day, and keep the printer in sleep mode to ensure that it isn’t shut off unnecessarily.
The Different Methods of Data Backup on a Desktop PC
Finding a reliable and easy way to backup important data has been a problem that software and hardware engineers have been working on since the early days of computing. There are many different methods available to users, and here we will look at a few of them, as well as the pros and cons of each.
Physical Media
Perhaps the most popular method of backing up important data is using physical media for backing up files, mainly thumb drives, external hard drives, or optical discs such as CD-Rs or DVD-Rs. While this is a very good way to quickly and easily back up important files, the user must remember to do it often for it to work, and sometimes important files can be missed in the process. The other problem with this solution is that the physical media is often stored in the same building or the same room as the user’s computer, meaning that a fire or other disaster could wipe out both copies of the file. Many programs are available to help automate this process, but usually still require input from the user.
Trading Media
Many users have devised a method of backing up to physical media and then taking one copy off the premises, to protect against disasters. In many cases, the user will use two external hard drives, swapping them after every backup with a friend or co-worker, to be stored at an off-site location. This helps eliminate the problem of disasters, but still relies on the user to remember to backup frequently.
Online Backup
The newest and perhaps most effective backup method involves using an online backup solution. These are generally programs designed to automatically backup important files over the internet when the user is away from the computer and store the files in a server or number of servers off-site. The files can then be retrieved when needed from any computer with the proper login information. This eliminates most of the problems mentioned above, as the user doesn’t have to remember to backup, but instead it all happens automatically in the background. The most popular services for online backup include DropBox, Carbonite, and Mozy.
With so many different backup methods available, it should be possible to find a solution that is simple and easy for your needs. With a little research, you can rest assured that your data is protected.
How is Printer Ink or Toner page yield determined?
Page yield can be a somewhat confusing term. At its simplest, the page yield of a printer ink cartridge or toner cartridge is the number of pages the cartridge is expected to print before it will be empty. Since the type of printing and print quality can play a major factor in the amount of ink or toner used, the predicted page yield can be a very subjective and sometimes inaccurate number, but let us take a look at how the page yield is determined.
Most manufacturers calculate the estimated page yield for a cartridge by calculating based on 5% coverage. That is to say that when an average page of text and graphics is printed, approximately 5% of the page will be covered in ink. This is only an estimate, however, as many pages will use more and less than 5% coverage, which will affect the overall page yield of the cartridge.
In more recent years, the ISO (International Organization for Standards) has released a set of standards for determining page yield. This process involves printing a test page or series of test pages until the cartridge reaches its end-of-life. Testing a monochrome cartridge involves a single test page which contains a combination of text and graphics, while testing color cartridges involves printing a series of 5 pages that use a variety of different images and patterns. In both cases, they are printed repeatedly until the cartridge is empty.
The great benefit of these ISO standard tests is that is provides a much better comparison between different models. Previous to this standard test, one manufacturer’s test procedures might have used very different page coverage than another’s. Today, any manufacturer who conforms to the ISO/IED 19752 or 19798 standards can be accurately compared with each other. This helps consumers make an informed decision by comparing the page yields of different models and cartridges in an accurate way.
5 Simple Things You Can Do To Speed Up Your Desktop PC
Many computer users experience slowdowns over time with any desktop PC. Unfortunately, as a computer gets slower, many of these users decide that it is time to purchase a new PC, but with just a few simple steps, it may be possible to regain much of this lost performance and speed, making your PC more enjoyable to use. Here are a few steps you can try to speed up your desktop PC.
The main cause of a computer slowing down over time is the amount of software installed on it. Many of the programs in your computer may be running in the background, consuming resources. Go to Control Panel, then Add/Remove Programs to see if there are any unused programs that can be uninstalled.
Viruses, spyware, and other malware can often cause a computer to run much slower. If you have antivirus installed, make sure it is up-to-date and then do a full scan of your PC, removing any malware it finds. There are many good free antivirus programs such as AVG antivirus available if you do not already have one installed. Many programs start automatically whether they need to or not. Check the Startup folder in your Start menu and remove any unnecessary programs. Also, you can right-click any programs in your taskbar and look for a setting to disable automatic startup. Remember that you can always open these programs manually when you actually need them.
If your desktop PC can support more RAM than it currently has installed, it is a good idea to upgrade the RAM to the maximum amount. This can have a significant impact on performance, as it allows more programs to be run at once with less slowdown. Defragging a hard drive will often not have a significant impact on performance, but a computer that has been in operation for a long time can sometimes have a very fragmented hard drive, which can hinder performance. Use the Windows defrag tool every few months or set it to run automatically for a little better disk performance.
If you try all of the steps above you should notice increased performance from your desktop PC. It may just be enough to save you from a costly upgrade or new computer purchase.
Common Symptoms of Defective Laptop Memory
Defective laptop memory can have a number of symptoms, but bad memory can be difficult to diagnose as it often shares symptoms with other defective components. In addition to the steps below, you can try a memory testing program such as Memtest86+ to check the health of your laptop memory. Let us look at a few of the most common symptoms of defective laptop memory and some of the troubleshooting steps and remedies available.
1. Crashes and Blue Screens
If you are experiencing crashing or blue screens while using your laptop normally, this could be a sign of defective memory. When the system tries to read from or write to a bad sector of the memory stick, it can often crash, causing the system to freeze up or display a blue screen error message. Try replacing the memory or running the system with only one memory stick at a time and see if the problem improves.
2. Crashes during Windows Installation
When installing Windows on a laptop, the system memory is utilized to a high degree. If you are continually experiencing crashes during installation of the operating system, you may have defective memory. Replace the memory to see if the problem is resolved.
3. System Won’t Boot
If your laptop will not boot correctly, it could be caused by defective memory, but this problem is trickier to diagnose as the symptom could also be caused by other faulty components, such as the mainboard. Try replacing the memory to see if the problem improves, as running a memory testing program may be impossible if the system will not boot.
4. Distorted Graphics
Faulty memory can sometimes cause flickering, discoloration, or other graphics problems, but this is also difficult to diagnose as a problem with the video card can also cause these problems. Rum a memory diagnostic tool or replace the memory to see if the situation improves.
Problems caused by defective laptop memory are certainly annoying, but replacing the memory is usually a very simple process for most laptops. Be sure to find memory that is specific to your model, and you may also consider upgrading the amount of memory in your laptop while you are doing the replacement.
