The printer can also connect through a network share.



12. What is the main problem occurs in the printer?

When you try to print paper nothing happens, This may be due to some connectivity issues, This problem is most commonly observed in the network printer, verify if there is an error in the LCD display, network cable plugin, In-network printer first verify the actual IP address

Streaks problem. This problem is due to the ink. You can use the printer software tools and manually cloth to clean the print head

Blank or Faded print problem is also due to dirt or low ink

Ghosting is the laser printer issue, There is a faint image print this issue is due to the Drum, after replacing Drum if same problems occur, there may be a fuser problem

Paper Jam is due to waste and dirt inside the printer or faulty pickup rollers

Paper creases are also due to waste inside the printer

Not correctly color printing this is due to the shortage of ink or faulty color cartridge

Printing is too slow Solution is to, Go to printer properties and select fast / economy under print quality

16. What is the type of LCD monitor?

TN(Twisted Nematic) in this type of monitor, when the light comes through it gets twisted by liquid crystals. This is a traditional technology with a poor viewing angle and color.

Twisted Nematic is cheaper than modern technology. The main applications are Digital watches, calculators.



IPS(In-plane Switching)

Unlike TN, In IPS, Liquid crystals remain in place instead of twist, They are aligned in parallel with glass. More transistors are used in IPS and it also consumes heavy power.

They are introduced to overcome the limitations of TN and thus result in the best color and viewing angle.

This is the basic question asked in IT support interview questions to analyze student. To troubleshoot monitor. Verify power switched on, power cable connections, disconnected or disordered data cable, disconnected or malfunctioning video card.

How to check it:

For the "No display problem" on your monitor, open your CPU and remove the Ram and clean it and fix it again.

Disconnect the other entire device except for the mouse, keyboard, and monitor. If you hear the voice of the fan spinning and light on the monitor then there is definitely a problem in the video card. Unscrew video card fan, CPU slot, and clean it with a brush.

We can plug the device back.

46. What is BSOD?

Blue Screen of Death is the most common error asked in remote desktop support interview questions. This message comes from the kernel of the operating system when it notices any problems with hardware, software, and applications, driver's conflicts, and viruses present in our operating system.

For example, if we have a 32-bit computer and we are trying to install that software which requires 64 bit. That software is not compatible with OS then we will face this blue screen error. To troubleshoot this verify all hardware and update all the drivers or run the computer in safe mode.

The following are some error message that comes on the blue screen.

The UNEXPECTED_KERNAL_MODE_TRAP error message is due to the failure of the hard drive, ram, or motherboard.
