Solutions

Diagnóstico rápido

This message typically appears after printing roughly 30,000 pages. If print quality is still acceptable, you may keep working, but it is wise to order a replacement drum unit (DR-421CL) before defects appear on your documents.

Solución paso a paso

  1. Check quality: Print a test page; if you see lines or smudges, the drum needs immediate replacement.
  2. Drum cleaning: Remove the drum unit and rotate the side gear to check for toner buildup on the photosensitive cylinder.
  3. Corona wire cleaning: Slide the green tab on top of the drum several times to clean the internal wire.
  4. Replacement: If replacing, install the new unit and reset the counter from the machine's menu.

Prevención y mantenimiento

  • Avoid touching the cylinder: Never touch the shiny surface of the drum, as skin oils can cause permanent marks.
  • Dust-free environment: Keep the printer in a clean area to prevent particles from scratching the cylinder.
  • Don't force prints: Once the definitive 'Replace Drum' error appears, print quality will drop significantly; avoid using the machine in this state.

Cuándo llamar a un técnico

Call a technician if, after replacing the drum, print quality remains poor or if you hear loud mechanical noises inside the chassis when the drum unit rotates.
