Solutions

Diagnóstico rápido

This is a warning, not a hard stop. Check your print quality: if vertical lines or repetitive spots appear, the drum is physically damaged and should be replaced immediately.

Solución paso a paso

  1. Check the status page in the LCD menu to confirm the remaining drum life percentage.
  2. Clean the corona wire by sliding the green tab on the drum unit from left to right several times.
  3. Order a replacement (DR-3400) so it is available before print quality degrades significantly.
  4. Replace the unit following screen instructions once the error changes to 'Replace Drum'.

Prevención y mantenimiento

  • Corona Wire Cleaning: Perform this every time you change the toner to prevent lines in prints.
  • Avoid Touching: Never touch the metal drum roller; skin oils can permanently degrade image quality.
  • Handling: When removing the drum unit, place it on a sheet of paper to avoid residual toner staining your workspace.
