The fuser could be dirty. For example it could be contaminated with toner.

15 pins. 3 rows with 5 pins each.

Tractor feed is the paper transport technology most commonly associated with dot matrix printers. Tractor feed uses a set of sprockets or tractors to pull the paper through the printer, ensuring accurate alignment and preventing paper jams. This method is particularly effective for continuous forms or multipart documents. It allows for reliable and precise paper movement, making it the preferred choice for dot matrix printers.

Bluetooth is used for personal area networking devices like keyboards and headphones.

PCMCIA stands for Personal Computer Memory Card International Association. It is a standard for connecting various devices, such as network cards or modems, to a computer. PnP (Plug and Play) means that the device can be connected to the computer without requiring manual configuration or installation of drivers. Hot Swappable means that the device can be connected or disconnected from the computer while it is still powered on. In Windows operating system, PCMCIA cards are designed to be both PnP and Hot Swappable, allowing for easy and convenient use of these devices. Therefore, the statement "PCMCIA is PnP and Hot Swappable in Windows" is true.

The smaller the dot pitch, the smaller the distance between the elements. This results in a clearer sharper image.

The PCI-E bus is a faster replacement for the standard PCI bus. It is capable of speeds from 1X (250 MB/s) to 16X (4GB/s). It is ideal for video but it can be used by any device currently supported by PCI.

SATA specifications and hardware permit only one device on each SATA cable. Multiple cable connections are available on the SATA controller for expansion.

MBR stands for Master Boot Record and is placed only on hard drives to enable reading it's file allocation table for the placement of files on it.

The Windows 2000 Backup Utility is capable of backing up data to tapes, zip drives, and recordable CD Roms. This means that users have the flexibility to choose the storage medium that best suits their needs and preferences. Whether they prefer the traditional tape backups, the convenience of zip drives, or the versatility of recordable CD Roms, the Windows 2000 Backup Utility can accommodate their choices.

There is no XP upgrade path for Windows 95 Operating System. Microsoft provides a free Upgrade Advisor. The Upgrade Advisor is the same tool that is used to scan your system for compatibility issues before you install Windows XP. You can also use the HCL.

A standard FireWire connection will support 100,200 and 400 Mbps. A faster standard IEEE 1394b is capable of supporting up to 800 Mbps.

Classic versions of the MAC OS are based on a proprietary core. OS X marked the move to UNIX.

A 168-pin RAM chip is a DIMM (Dual Inline Memory Module). DIMMs are a type of memory module that have a 168-pin connector and are commonly used in desktop computers. They provide a higher data transfer rate compared to SIMMs (Single Inline Memory Modules) and are more commonly used in modern computer systems. The term "parity" refers to a type of error checking mechanism in RAM modules, but it is not applicable to the given 168-pin RAM chip. Therefore, the correct answer is DIMM.

To set a printer as the default printer in Windows 2000, you would go to the printers folder, right-click on the desired printer, and select "set as default printer." This action will make the selected printer the default option for all print jobs unless specified otherwise.

The nozzle gate, which is closed when the printer is idle, prevents the ink from leaking out of the cartridge.

The most probable fault for a smeared page from a laser printer is a bad fuser unit. The fuser unit is responsible for heating and pressing the toner onto the paper, and if it is not functioning properly, it can cause the toner to smear on the page. Low toner, dirty corona wires, and poor quality paper may affect print quality, but they are less likely to cause smearing.

Chip creep refers to the problem of chips that, over time, would work their way out of the socket. Chip creep occurs due to thermal expansion; the contracting and expanding during system heat up and cool down.

In order to extend battery life and reduce heat the mobile processor scales its clock speed to match the demands of the system. At top speed this processor runs at 1.6 GHz.

The Sony/Phillips Digital Interface is designed to transfer digital signals between devices without degrading the signal by converting it to analog. This preserves the quality of the signal delivered to digital recording and playback devices.

When upgrading a System BIOS, it is important to write down all the settings before proceeding. This is because upgrading the BIOS can sometimes reset the settings to their default values, which may cause issues or conflicts with the hardware or software. By writing down the settings, the user can easily restore them after the upgrade, ensuring that the system functions properly. Shutting down peripherals, saving upgrade files, and unplugging connectors are also important steps, but they are not as crucial as preserving the settings.

This computer needs to be replaced, check to see if it’s still under warranty.

The print driver could be incorrect or the print cable might be loose.

The capacity of a DVD-R DL disk is 8.5.

BIOS is run 1st (Code found in the CMOS chip on the motherboard). Bios code starts up the computer with POST (Power on Self Test) and then loads the OS.

Never overlook the obvious. Perform problem determination by checking all connections first, and that includes power connections. If the PC is plugged in, a faulty AC outlet would cause a dead computer.
