Question #21
A user reports that a printer pulls multiple sheets of paper from the paper tray instead of a single sheet.
Which of the following should a technician investigate to resolve this issue? (Select two).
- A . Toner cartridge
- B . Tractor feed
- C . Pickup roller
- D . Separation pad
- E . Duplexer
- F . Fuser
Correct Answer: CD
CD
Explanation:
The correct answers are C. Pickup roller and D. Separation pad.
A pickup roller is a rubber wheel that grabs the paper from the paper tray and feeds it into the printer. A separation pad is a small piece of cork or rubber that prevents more than one sheet of paper from being fed at a time. If the pickup roller or the separation pad is worn out, dirty, or damaged, it can cause the printer to pull multiple sheets of paper instead of a single sheet. This can lead to paper jams, misprints, or wasted paper.
To resolve this issue, a technician should investigate the condition of the pickup roller and the separation pad and replace them if necessary. The technician should also clean the paper tray and make sure the paper is loaded correctly and not stuck together.
A toner cartridge is a component that contains the toner powder used to create the printout on a laser printer. A tractor feed is a mechanism that uses sprockets to move continuous paper through a dot matrix printer. A duplexer is a device that allows a printer to print on both sides of the paper automatically. A fuser is a part of a laser printer that melts the toner onto the paper using heat and pressure. None of these components are related to the issue of pulling multiple sheets of paper from the paper tray.

Question #23
A user connects a laptop to a conference room audiovisual system using a VGA cable. The TV displays the image correctly, but the audio is not working.
Which of the following will most likely resolve the issue?
- A . Replacing the VGA cable
- B . Switching inputs
- C . Using HDMI to connect
- D . Restarting the audiovisual system
Correct Answer: C
C
Explanation:
VGA (Video Graphics Array) cables transmit analog video signals only and do not carry audio signals. When a user connects a laptop to an audiovisual system using a VGA cable, the lack of audio is due to VGA’s inability to transmit sound. Switching to an HDMI (High-Definition Multimedia Interface) cable, which supports both audio and video signals, will most likely resolve the issue by enabling the transmission of sound to the audiovisual system alongside the video.

Question #24
A customer reports that, after a technician replaced a laptop screen, the laptop is only able to connect to a Wi-Fi network if it is positioned very close to a wireless access point.
Which of the following should the technician verify first?
- A . The internal antennas are connected.
- B . The device has the latest OS updates.
- C . The wireless device drivers are the latest version
- D . Airplane mode is disabled.
- E . The battery is charging.
Correct Answer: A
A
Explanation:
The internal antennas are the components that allow the laptop to receive and transmit wireless signals from and to the wireless access point. The internal antennas are usually located inside or around the laptop screen, and they are connected to the wireless network card or adapter by thin wires or cables. If the internal antennas are disconnected, damaged, or misaligned, the laptop may experience wireless connectivity issues, such as low signal strength, limited range, or intermittent connection.
In this scenario, a customer reports that, after a technician replaced a laptop screen, the laptop is only able to connect to a Wi-Fi network if it is positioned very close to a wireless access point. This could indicate that the technician accidentally disconnected or damaged the internal antennas during the screen replacement process, and that the laptop is not receiving enough wireless signals from the wireless access point. Therefore, the first thing that the technician should verify is that the internal antennas are properly connected and positioned inside or around the laptop screen. To verify and reconnect the internal antennas, the technician should follow these steps:
Turn off the laptop and disconnect it from any power source or external device.
Remove the battery and any screws that secure the laptop screen bezel.
Carefully pry off the laptop screen bezel and expose the internal antennas.
Check if the internal antennas are intact and securely connected to the wireless network card or adapter. The internal antennas may have different colors or labels, such as black, white, gray, main, aux, or 1, 2.
If the internal antennas are disconnected or loose, reconnect them to the corresponding connectors on the wireless network card or adapter. Make sure that they snap into place and that there is no gap or bend in the wires or cables.
If the internal antennas are damaged or broken, replace them with compatible ones. Make sure that they have the same length and shape as the original ones.
Realign and reposition the internal antennas inside or around the laptop screen. Make sure that they do not interfere with any other component or cable, and that they follow the original path and direction.
Reattach the laptop screen bezel and secure it with screws.
Reinsert the battery and turn on the laptop.

When a user tries to print a document on a laser printer, vertical lines appear on the printout.
Which of the following should the technician replace?
- A . Mirror
- B . Fuser
- C . Drum
- D . Toner
Correct Answer: C
C
Explanation:
Vertical lines on a laser printer printout are most commonly associated with issues in the drum unit.
The drum is a crucial component in the laser printing process, where it receives an electrostatic image of the document to be printed and transfers toner to the paper. If there are defects or damage to the drum’s surface, it can result in vertical lines appearing on the printed output as the drum fails to evenly distribute toner across the page.

Question #30
A user reports that a computer has been randomly shutting down without warning.
Which of the following is the most likely cause of the issue?
- A . Corrupted OS
- B . Incompatible memory modules
- C . Overheated CPU
- D . Low system resources
Correct Answer: C
C
Explanation:
An overheated CPU is the most likely cause of a computer that has been randomly shutting down without warning. A CPU generates heat when it performs calculations, and if the heat is not dissipated properly, it can damage the CPU or cause it to malfunction. A computer that shuts down randomly is a common symptom of an overheated CPU, as the system tries to protect itself from further damage by shutting down or restarting.
The other options are not as likely to cause this issue. A corrupted OS may cause the computer to crash, display errors, or fail to boot, but it does not affect the CPU temperature or the system fan. Incompatible memory modules may cause the computer to beep, display a blue screen, or fail to recognize the installed RAM, but they do not cause the CPU to overheat or the system to shut down randomly. Low system resources may cause the computer to slow down, freeze, or display a low memory warning, but they do not affect the CPU temperature or the system fan.
To troubleshoot and resolve an overheated CPU issue, the user should check and clean the air vents, provide proper ventilation, apply thermal paste, replace the fan or the heat sink, or upgrade the CPU if necessary. The user should also update the BIOS and the device drivers, adjust the power settings, and monitor the system temperature using diagnostic tools.
