Step-by-Step Solution

  1. Power Off: Disconnect the device immediately.
  2. Cooling: Leave the unit off for 20 minutes to dissipate heat.
  3. Inspection: Open the rear cover to check for paper scraps blocking the fuser.
  4. Restart: Reconnect and observe if the system status is cleared.

Prevention and Maintenance

Avoid back-to-back high-volume printing in non-ventilated rooms. Use only genuine consumables to ensure proper toner fusing temperatures.
