   Vertical streaks are appearing on the output of a laser printer. Which of the following items is the MOST likely cause?

   • ARoller
   • BDrum
   • CTransfer belt
   • DRibbon

   Show answer

   Answer: B

   Explanation

   The drum is the most likely cause of vertical streaks appearing on the output of a laser printer. A laser printer uses a complex process to produce high-quality printed documents. The printer's drum is a critical component in this process, as it is responsible for transferring the image onto the paper. The drum is coated with a thin layer of electrically charged toner, which is attracted to the areas of the drum that have been exposed to the laser beam. When the drum rotates, it transfers the toner onto the paper, which is then fused to the paper by the printer's fuser. If the drum is damaged or worn, it can cause various issues with the print quality, including vertical streaks on the output. Other possible causes of vertical streaks include problems with the printer's roller or transfer belt, or issues with the toner itself.

   A company has a dot matrix printer that uses carbon paper. The company reports that the first page is printing too light, although the following pages are still legible. Which of the following MOST likely needs to be fixed?

   • AThe print drum is worn and loose, causing the printing to be light in places.
   • BThe ribbon is low on ink or missing and must be replaced to get proper output.
   • CThe heating element has failed, and a new one needs to be installed for proper transfer.
   • DThe wrong type of filament is loaded, preventing it from sticking correctly.
   • EThe fuser assembly is not calibrated properly, causing it to impact the paper too hard.

   Show answer

   Answer: B

   Explanation

   B is the only logical explanation! A is a laser printer C is Thermal printer D is 3D printer E I think is also a laser printer All of which do not have a ribbon other than the dot matrix printer. Therefore B is the only correct answer. Also I think that dot matrix is the only printer to use tractor feeders and carbon paper. Correct me if I'm wrong please :)

   A user added a heater underneath a desk, and now an external monitor is not working. A technician verified the monitor gets power. Which of the following should the technician do next?

   • AHave the user unplug the heater.
   • BReplace the monitor.
   • COpen the display settings on the computer.
   • DEnsure a VGA cable is connected properly.

   Show answer

   Answer: D

   Explanation

   Who the hell uses VGA anymore? But yeah, I guess A or D could be valid... Frankly, I would undo the last change first, the user installed the heater, then the monitor stopped working, my first recommendation would be to unplug the heater and see what happens, then check cable if that doesn't work. It's also very likely he knocked out the cable, now that I think about it, checking that first probably makes more sense than a heater interfering with a monitor somehow.
