The fuser unit.

  1. The fuser ✔
  2. The photosensitive drum
  3. The toner cartridge

Why: Laser printing projects the image onto a photosensitive drum, toner sticks to the charged areas, the drum transfers toner to paper, and the fuser applies heat and pressure to bond it permanently.

Huh, didn't know that: Ricoh says users may need to occasionally replace the drum or the fuser.

Did you hear about the octopus who stopped printing? It ran out of ink!
