Solutions

Diagnóstico rápido

The OXC4EB827F manifests immediately after a cartridge replacement or after long periods of inactivity. You will know it is this error because the screen displays an 'Ink System Failure' message. If cartridges are properly seated but the error persists, the issue lies within the ink pump pressure sensor.

Solución paso a paso

  1. Cartridge removal: Open the access door and remove all four (CMYK) ink cartridges completely.
  2. Contact inspection: Verify that the gold chips on the back of the cartridges are clean and free of dried ink or debris.
  3. Firm reseating: Reinsert cartridges one by one, ensuring you hear a 'click' confirming the spring-loaded lock has engaged.
  4. System reset: With the printer on, disconnect the power cord for 60 seconds and reconnect it to force a new consumption detection cycle.

Prevención y mantenimiento

Avoid leaving the printer unused for periods exceeding two weeks to prevent injector clogging due to dried ink. Use only original consumables to ensure chips have the compatible firmware version. Run printhead cleaning whenever the maintenance assistant suggests it.

Cuándo llamar a un técnico

If the error code returns after reseating the cartridges and running a reset, there is likely a mechanical failure in the ink pump or pressure regulator, requiring expert technician intervention.
