Canon PIXMA iP2820 error P07: Waste Counter

Canon PIXMA iP2820 error P07 is another identifier for the ink waste counter reaching its manufacturer limit. The printer identifies that internal pads have absorbed their maximum capacity and subsequently locks down to prevent leakage. This is a common software-based limitation designed to protect your physical printer from spilling ink. Resetting the EEPROM memory can bypass this.

Common causes

  • 1EEPROM Counter: The cleaning cycle counter has reached its max capacity.
  • 2Logic overflow: The system calculates the absorber cannot hold more ink.
  • 3Maintenance cycle usage: Frequent cleaning depletes the waste ink capacity faster.
  • 4Factory settings: Rigid limit on total print volume set by Canon.

Solutions

Diagnóstico rápido

The P07 code appears on your PC screen when attempting to print or via a blinking LED pattern on the printer. It signals that your page count, including maintenance cleans, has maxed out.

Solución paso a paso

  1. Enter service mode: Hold the Stop button and press the power button until light states change.
  2. Run reset: Press the Stop button multiple times to reset the EEPROM memory according to the waste counter.
  3. Completion: Power off and restart to check if P07 error is cleared.
  4. Validation: Print a test document to ensure the logic was reset successfully.

Prevención y mantenimiento

Avoid repetitive manual head cleaning if not absolutely necessary. Each cycle adds to the waste ink counter, causing the error P07 to appear much sooner.

Cuándo llamar a un técnico

If you cannot enter service mode despite following the timing precisely, the printer's main logic board might have suffered a software failure.
