Question about HP LaserJet 2820 Printer
Could be a bad laser, or the laser shutter may not be opening. If the Laser shutter is not opening. it can be because the printer cover has a broken notch. The notch pushes a button under the cover to open the shutter.

Tips for a great answer:
Isolate to a wall outlet and not a strip.
Remove the cartridges.
Remove the power plug and then reconnect.
Reinstal the cartridges.
Try to do a copy direct from the unit.
Print a self test page and check for Yellow or Magenta to rule out a partially empty cartridge.
