Solutions
Diagnóstico rápido
An E3 error light indicates that the system is not communicating with the toner's chip. This is a common occurrence after a cartridge replacement if the unit was not pushed into its housing firmly enough to connect the electrical pins.Solución paso a paso
- Access: Open the front door and remove the toner unit.
- Clean: Carefully wipe the gold chip contacts on the toner cartridge with a microfiber cloth.
- Reseat: Insert the toner back into the printer with firm pressure until it clicks into the locking position.
- Verify: Close the door and check if the error light turns off.
Prevención y mantenimiento

Regularly vacuum or wipe out the toner compartment to prevent dust from accumulating on the printer's internal pins. Using original HP supplies is the best way to ensure the chip is perfectly compatible.Cuándo llamar a un técnico
