Like your camera, there are a few common reasons why microphones don't work. 

  • It's not plugged in or turned on
  • The batteries are not charged
    • Put it on the charging stand. If you need new batteries, or your stand isn't working, we will provide you with replacements. 
  • There is another microphone somewhere that is plugged in (rare)
    • Occasionally there could be an audio input device that was left inside a teacher's cart or is integrated with an existing webcam. This can be solved by removing this device and restarting your PC.

Too loud/quiet or creating feedback

If your mic is too loud, or producing static feedback, you can lower the output volume on either the microphone or on the switcher. 

Conversely, a quiet microphone can be remedied by raising the volume, however this can make it produce feedback, so it is up to your discretion what sound level is appropriate.

My Loom video recording is stuck uploading

Email us the video link and we will forward the link to Loom support

My webcam doesn't appear in Loom

If you want to use Loom and use your webcam, I highly recommend turning your doc cam off prior to opening Loom. Once you have opened Loom and begun the recording, you can then turn on the doc cam. If your doc cam isn't turned off, it seems that Loom will continuously try to access the doc cam and will not allow you to select the webcam.

Loom will not open

Loom is crashing my Chrome browser

Restart chrome or your computer.

Loom has its own troubleshooting page if you'd like to check it out.



First, please make sure that "Doc Cam" is selected on X panel or that "PC 2" is selected on the switcher, and that your projector is turned on.

Projecting computer screen

If you want to be able to extend your computer screen, like having two different monitors, hold down the windows button and P at the same time, then select extend. 

Alternatively, if you'd like to duplicate your display to the projector exactly. Do the same thing but hit duplicate.

Projecting Document camera

Hold down the USB/VGA/ESC button for about 5 seconds or until you hear a click. If this doesn't work try restarting your PC and try it again.


If you're phone isn't working, just try to unplug the cable and plug it back in.

Don't try to be a hero.

If it doesn't work, we'll come and replace either the handset, the cable, or more.


There are a few reasons why your camera may not be working

  • It's not plugged in
    • That would be an extremely embarrassing tech ticket.
  • There's a program open that's already using your camera
    • Besides making sure everything is plugged in, make sure there is nothing open that is accessing the camera. For instance, if you have Google Meets open and it's using your camera, you wouldn't be able to join a Zoom call and use that same camera.
  • Your computer cannot find or recognize it
    • If this is the case, we would suggest restarting your computer, as it might be having problems updating devices such as cameras.


If you're trying to use your document camera, make sure "Doc Cam" is selected on X Panel, or "PC 2" is selected on the switcher scalar. Then, hold down the USB/VGA ESC button for 5 seconds, or until you hear a click. Then it should switch to the document camera. You can test this by opening the Camera app on windows by simply typing in "camera" in the search box at the bottom-left of the screen.

Google Meets

If you want to be able to switch from your normal camera to the document camera or vice versa, click on the three dots in the bottom-right corner of Google Meets, click on settings, video, and then select your video input. If the desired one isn't coming up, please refer to the steps above.


Printers, we all hate em.

Try the following steps, and if there are still issues, we'll look into the issue further. 

  • Restart both your computer and the printer
  • Check to see that the printer has ink and paper
  • Make sure the paper isn't jammed inside the printer
  • Make sure you're printing to the right printer

This is by no means an exhaustive list, however it should fix the majority of faulty printer cases.
