D. 15 meters
146 A technician has just installed a duplexer on a laser printer. The duplexer was sold by the manufacturer and is compatible with the printer. However, the printer properties will not let anyone choose to print on both sides of the paper. What might resolve the issue?
A. Removing and reinstalling the duplexer
B. Turning the printer off and back on
C. Upgrading the printer’s firmware

147 You have a desktop computer with three PCI expansion slots. What will happen when you mix cards of different speeds on the same motherboard?
A. The cards will operate at their original speeds.
B. None of the cards will function.
C. The cards will all operate at the faster speed.
D. The cards will all operate at the slower speed.
148 Which of the following statements accurately explains what happens during the exposing step in the laser printer printing process?
A. A laser reduces areas of the drum from a strong negative charge to a slight positive charge.
B. A laser reduces areas of the drum from a strong negative charge to a slight negative charge.
C. A laser increases areas of the drum from a slight negative charge to a strong negative charge.
D. A laser increases areas of the drum from a slight positive charge to a strong positive charge.
149 Which of the following is the defining characteristic of a passive cooling system for a CPU?
A. It uses water.
B. It uses heat pipes.
C. It uses liquid nitrogen or helium.
D. It does not require a fan or power.
150 You have an older laptop with a CD burner in it. What is the approximate capacity of the CDs you will be able to create with this device?
A. 350MB
B. 700MB
C. 1.4GB
D. 4.7GB
151 Which of the following system settings are configurable in the BIOS? (Choose two.)
A. Date and time
B.
A, D. USB flash drives and SD cards are hot swappable. (In the case of USB, be sure that the flash drive does not contain key file system files needed for the computer to run!) Hybrid SSDs might or might not be hot swappable and are larger than USB and SD drives. PATA devices are generally not hot swappable.
C. This SLI-ready motherboard has three PCIe x16 slots (every other slot, starting with the top one), one PCIe x1 slot (second slot from the top), and two PCI slots (first and third slots from the bottom). Notice the latch and tab that secures the x16 adapters in place by their hooks.
B, D. Dual-channel motherboards have two banks of two RAM slots. They are color coded such that the two slots of the same color belong to the same channel. Sometimes the like-colored slots are adjacent to each other, but other times they alternate. For optimal performance, fill one channel completely.
C. Install an application that provides support for printing to .pdf. Then, when the user opens the print window, they can choose the .pdf option.
A. The boot sequence of a computer is changed in the BIOS settings.
C, D. Typical front- or top-panel connectors include USB, audio, power button, power light, drive activity lights, and the reset button. Hard drives and optical disk players generally connect to the motherboard.
A. USB 3.0 has a cable length limitation of 3 meters. USB 2.0 cables can be up to 5 meters in length.
C. Printer firmware upgrades can offer newer features that are not available on previous versions.
D. PCI is a shared-bus topology, so mixing 33MHz and 66MHz adapters in a 66MHz system will slow all adapters to 33MHz.
B. In the exposing step, the image is written to the photosensitive imaging drum. Wherever the laser beam touches, the photosensitive drum’s charge is severely reduced from –600VDC to a slight negative charge (around –100VDC). As the drum rotates, a pattern of exposed areas is formed, representing the image to be printed.
D. Passive cooling systems come in a variety of models, and some are very effective. The defining characteristic is that they do not use a fan or require a power source.
B. Compact discs have a capacity of approximately 700MB. Other CD standards support capacities of 650MB, 800MB, and 900MB.
A, C. The BIOS configures many hardware components and settings, such as system date and time, boot sequence, enabling and disabling devices, clock speeds, virtualization support, and BIOS security.
