Review the safety notices in the multilingual translations section (page 8), the safety information section (page 20), and the laser compliance statement (page 26) before any service work.
Test each FRU individually and replace only the one that changes the symptoms; if a replacement does not fix the problem, reinstall the original FRU before proceeding.
Run a low‑level format first and ensure the correct drive is selected to avoid overwriting data or programs.
