Safety policy

Stop if a procedure exceeds your experience or your printer’s manual. Power off and unplug the printer before opening service panels. Laser-printer fusers can remain dangerously hot; high-voltage components can retain charge.

Warning levels

Caution

A wrong sequence may damage the printer, erase settings, or affect warranty coverage.

Hazard

Potential heat, electrical, sharp-edge, ink, or moving-part risk. Follow the manufacturer procedure exactly or use a qualified technician.
