This Is How A Printer Drum Works

[caption id="" align="alignleft" width="200" caption="Xerox Printer Drum"][/caption]

All printer drums are a key and essential part of a printer. The drum works or its job is to be an image holder of documents in the printer. When you write on the computer and make a command to print the words then it (the drum) makes the whole document into one picture as a reverse image of the document. Then a negative charge is created on the drum as the drum continues to roll as it approaches the toner hopper. Then the positive charged toner element strikes or takes on the image created on the drum.  It does this when it becomes close to the paper and when the print cycle is almost complete. Printer drums work differently from laser printers cartridges which is a subject for another post.

ADF Automatic Document Feeders Speed Things Up

For maximizing efficiency when handling documents, an ADF Automatic Document Feeder function in your printer, fax machine, photocopier or scanner is ideal. The ADF Automatic Document Feeder takes multiple pages and feeds these one at a time into the printer or scanner, so that you can process documents with multiple pages without manually feeding every page into the machine. Feeders can range in speed of action and number of pages processed, ranging from 10 sheets to 200. An ADF Automatic Document Feeder will improve your workflow and help you to print, scan and process documents faster, without having to put every page through yourself.

Should You Switch From From DDR2 to DDR3 Memory ?

Many motherboards support using both DDR2 and DDR3 memory, but the only problem is that the processor used can dictate which type of memory is acceptable to install. For example, using an Intel Core i7 or i5 processor means you're going to have to use DDR3 memory, no matter what your motherboard supports. On the other hand, some processors only support DDR2. So be sure to read your motherboards instructions carefully, otherwise you could end up wasting your money.

Now, with that being said, if you find yourself in the position of having to choose between both types of memory - and there are no technical hurdles in the way - then this becomes a question of price versus performance. DDR2 is very economical. Well, to put it bluntly, DDR2 memory is cheap. DDR3, in comparison, is pretty expensive. While you do get a slight performance advantage with DDR3, the real advantage is your ability to upgrade. DDR2 is old technology, and it's slowly being phased out (slowly being the key word here). In the future, almost every computer will use DDR3 memory, and upgrading from DDR2 is going to be a hassle. On the other hand, you can get a lot more memory by buying DDR2 now. In fact, you can get almost double the amount of RAM by buying DDR2 memory instead of DDR3. For those that recall the transition from DDR1 to DDR2, the move from DDR2 to DDR3 will be much the same. It will take years for DDR3 to become main stream.  Lastly, those with a DDR2 motherboard have nothing to worry about as DDR2 production will continue with even improved parts still on the drawing boards.

Parts of a computer

If you use a desktop computer, you might already know that there isn't any single part called the "computer." A computer is really a system of many parts working together. The physical parts, which you can see and touch, are collectively called hardware. (Software, on the other hand, refers to the instructions, or programs, that tell the hardware what to do.)

The illustration below shows the most common hardware in a desktop computer system. Your system may look a little different, but it probably has most of these parts. A laptop computer has similar parts but combines them into a single notebook-sized package.
Picture of a desktop computer systemDesktop computer system

Let's take a look at each of these parts.
System unit

The system unit is the core of a computer system. Usually it's a rectangular box placed on or underneath your desk. Inside this box are many electronic components that process information. The most important of these components is the central processing unit (CPU), or microprocessor, which acts as the "brain" of your computer. Another component is random access memory (RAM), which temporarily stores information that the CPU uses while the computer is on. The information stored in RAM is erased when the computer is turned off.

Almost every other part of your computer connects to the system unit using cables. The cables plug into specific ports (openings), typically on the back of the system unit. Hardware that is not part of the system unit is sometimes called a peripheral device or device.
Picture of a system unitSystem unit

Storage

Your computer has one or more disk drives—devices that store information on a metal or plastic disk. The disk preserves the information even when your computer is turned off.
Hard disk drive

Your computer's hard disk drive stores information on a hard disk, a rigid platter or stack of platters with a magnetic surface. Because hard disks can hold massive amounts of information, they usually serve as your computer's primary means of storage, holding almost all of your programs and files. The hard disk drive is normally located inside the system unit.
Picture of a hard disk driveHard disk drive
CD and DVD drives

Nearly all computers today come equipped with a CD or DVD drive, usually located on the front of the system unit. CD drives use lasers to read (retrieve) data from a CD, and many CD drives can also write (record) data onto CDs. If you have a recordable disk drive, you can store copies of your files on blank CDs. You can also use a CD drive to play music CDs on your computer.
Picture of a CDCD

DVD drives can do everything that CD drives can, plus read DVDs. If you have a DVD drive, you can watch movies on your computer. Many DVD drives can record data onto blank DVDs.
Tip
Tip

If you have a recordable CD or DVD drive, periodically back up (copy) your important files to CDs or DVDs. That way, if your hard disk ever fails, you won't lose your data.
Floppy disk drive

Floppy disk drives store information on floppy disks, also called floppies or diskettes. Compared to CDs and DVDs, floppy disks can store only a small amount of data. They also retrieve information more slowly and are more prone to damage. For these reasons, floppy disk drives are less popular than they used to be, although some computers still include them.
Picture of a floppy diskFloppy disk

Why are floppy disks "floppy"? Even though the outside is made of hard plastic, that's just the sleeve. The disk inside is made of a thin, flexible vinyl material.

Mouse

A mouse is a small device used to point to and select items on your computer screen. Although mice come in many shapes, the typical mouse does look a bit like an actual mouse. It's small, oblong, and connected to the system unit by a long wire that resembles a tail. Some newer mice are wireless.
Picture of a computer mouseMouse

A mouse usually has two buttons: a primary button (usually the left button) and a secondary button. Many mice also have a wheel between the two buttons, which allows you to scroll smoothly through screens of information.
Picture of mouse pointers

When you move the mouse with your hand, a pointer on your screen moves in the same direction. (The pointer's appearance might change depending on where it's positioned on your screen.) When you want to select an item, you point to the item and then click (press and release) the primary button. Pointing and clicking with your mouse is the main way to interact with your computer. For more information, see Using your mouse.
Top of page
Keyboard

A keyboard is used mainly for typing text into your computer. Like the keyboard on a typewriter, it has keys for letters and numbers, but it also has special keys:

The function keys, found on the top row, perform different functions depending on where they are used.

The numeric keypad, located on the right side of most keyboards, allows you to enter numbers quickly.

The navigation keys, such as the arrow keys, allow you to move your position within a document or webpage.

Picture of a keyboardKeyboard

You can also use your keyboard to perform many of the same tasks you can perform with a mouse. For more information, see Using your keyboard.
Top of page
Monitor

A monitor displays information in visual form, using text and graphics. The portion of the monitor that displays the information is called the screen. Like a television screen, a computer screen can show still or moving pictures.

There are two basic types of monitors: CRT (cathode ray tube) monitors and LCD (liquid crystal display) monitors. Both types produce sharp images, but LCD monitors have the advantage of being much thinner and lighter. CRT monitors, however, are generally more affordable.

Printer

A printer transfers data from a computer onto paper. You don't need a printer to use your computer, but having one allows you to print e‑mail, cards, invitations, announcements, and other materials. Many people also like being able to print their own photos at home.

The two main types of printers are inkjet printers and laser printers. Inkjet printers are the most popular printers for the home. They can print in black and white or in full color and can produce high-quality photographs when used with special paper. Laser printers are faster and generally better able to handle heavy use.

Speakers

Speakers are used to play sound. They may be built into the system unit or connected with cables. Speakers allow you to listen to music and hear sound effects from your computer.
Picture of computer speakersComputer speakers
Top of page
Modem

To connect your computer to the Internet, you need a modem. A modem is a device that sends and receives computer information over a telephone line or high-speed cable. Modems are sometimes built into the system unit, but higher-speed modems are usually separate components.

Junk Well Written (DK) Shopping for Quality Platens and Other Office Equipment

It must be of the utmost priority that obtaining these types of equipment be given much time and consideration. Another thing to have in mind before coming to a decision is the price of any equipment. It is, therefore, highly recommended to canvass and scrutinize the quality of the office equipment to acquire.

Junk (DK) Drums not to rock

We are all familiar with those rocking drums, associated with music. But have you heard off a laser printer drum. Firstly, let me introduce you to a laser printer, just like a computer printer it also prints texts and graphics on plain piece of paper. Therefore, drum is the inseparable part of the laser printer, like every copier. Both these laser printer and copiers have drums that help in producing an image, while transferring it to a paper. But there lies a difference between these two; the image is transcribed differently in case of laser printers. Above all the print image needs to be inscribed necessarily in the drum.

Tempted To Buy A LCD TV?

LCD (Liquid crystal display) TVs are especially tempting for people these days versus an older style tube based TV. LCD TV's futuristic look and its more vibrant colors can tempt a TV addict to spend money or spend more money they should even in the midst of the recent economic downturn.

Like old fashioned TVs an LCD television screen consists of pixels each of which can show a viewer thousands of colors. The high near photo quality on an LCD TV screen is due to the really high number of pixels on the screen. The pixels are counted from one side to the other and from top to bottom. The higher the number of pixels then the better, sharper and clearer the picture will be. It is the composition of these pixels that forms the picture displayed on a TV screen or computer monitor.  Color...
