Solutions

Diagnóstico rápido

The I-01 error is straightforward: the printer internal counters have determined that ink levels are low. Check the visible ink level windows at the front of your printer to confirm the reported status.

Solución paso a paso

  1. Check ink tanks to identify the low color.
  2. Refill the tank using T522 genuine ink until it reaches the upper line.
  3. Close the tank cover and secure the bottle filler area.
  4. Reset the counter in the printer panel menu to notify the system of the refill.

Prevención y mantenimiento

Always maintain ink levels between the bottom and top lines. Never let the ink levels drop completely, as this risks air entering the print heads, which can be difficult and costly to fix.

Cuándo llamar a un técnico

If the reset does not clear the I-01 error, there may be a fault with the ink level sensor module, and you should contact technical support.
